Objective The Atlantic provinces’ science curriculum is guided by the vision that all students will have an opportunity to develop scientific literacy.

Scientific literacy is an evolving combination of the science-related attitudes, skills, and knowledge that students need to develop inquiry, problem-solving, and decision-making abilities, to become lifelong learners, and to maintain a sense of wonder about the world around them. Foundation for the Atlantic Canada Science Curriculum, page 11

The Spotlight on Science Skills series of documents: -­‐ Clusters the existing Atlantic Canada skill outcomes into nine scientific practices

(questioning, predicting/hypothesizing, variables, experimental design, collecting data/observations, organizing/displaying data, analyzing data, making conclusions, applying learning).

-­‐ Provides educators with an elaboration of the scientific practice including explanations of specialized terminology. It indicates what students have learned in previous grades and what the focus is for learning in the current grade.

-­‐ Provides a list of achievement indicators with an accompanying rubric for each scientific practice to further clarify expectations and guide educators in determining whether their students have met the outcome.

GCO: Plan & Perform (PP) Ask questions, make predictions about objects and events and develop fair tests to investigate those questions. Observe and investigate their environment and record the results SCO: PP1 Propose scientific questions Scope and Sequence of Outcomes

Grades K-3 Grades 4-6 Grades 7-9 200-1 Ask questions that lead to the exploration and investigating 204-1 Propose questions to

investigate and practical problems to solve

208-2 Identify questions to investigate arising from practical problems and issues 200-2 Identify problems to be

solved

204-2 Rephrase questions in a testable form

208-1 Rephrase questions in a testable form and clearly define practical problems 208-3 Define and delimit questions and problems to facilitate investigation

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? Before writing a testable question, students will be able to pose an initial scientific question. Scientific questions may have different purposes: for research, leading to an innovation, or designing an experiment. If the question is a yes or no answer or an opinion, students should be encouraged to rewrite the question to be unbiased.

Research Innovation Experiment/Investigation How does a tuning fork make salt jump?

How might we make this better?

What happens if I use another tuning fork?

Will there be a full moon tonight?

What type of fertilizer will make grass grow greener?

What changes can be made to make this work more efficiently?

From an initial scientific question, students are able to alter a scientific problem or question into a testable form. A testable question is one that can be answered by designing and conducting an experiment. In order for a question to be deemed testable, the question must clearly identify the variable to test and the variable to measure. Testable questions are always about changing one thing to see what the effect is on another thing. Testable questions have two parts: Independent and Dependent Variables The independent variable (IV) is the variable that will be changed by the scientist. A good experiment has only one independent variable. The dependent variable (DV) is the variable being measured in the experiment.

• Scaffold 1- Does changing __IV___ affect __DV___? • Scaffold 2 - How does changing __IV___ affect __DV___?

Connection to Communication

• Communicate questions, ideas, and intentions, and listen

• Ask others for advice or opinions

• Scaffold 3 - If I change __IV___, will it affect __DV___? • “If they wash their hands (variable to be tested/IV), will the number of days

students are absent decrease (variable to measure/DV)?

Initial Scientific Question Testable Question

What happens if I use another tuning fork? If we use different types of tuning forks, will the rate of sound vibrations be the same?

What changes can be made to make this work more efficiently?

Does changing the type of light bulb affect energy consumption?

Students should understand that precise language is very important to writing a good testable question. Students should be encouraged to change terms such as “better” and “improve” with the specific measure to be improved. For example:

“If I change the wheels, will it improve how the car rolls?” is a statement approaching expectations, since the variable to be measured is not specific and is open to interpretation.

“If I change the wheels, will it increase the distance travelled?” is a statement meeting expectations because it indicates what will be measured. Achievement Indicators Guiding Questions: • What evidence will I look for to know that learning occurred? • What should students demonstrate to show their understanding of the Scientific Process Skill? Use the following set of indicators as a guide to determine whether students have met the corresponding specific outcome.

i. Write questions using language that suggests an investigation ii. Develop testable questions that indicate the variable to test (independent variable) iii. Develop testable questions that indicate the variable to be measured/observed

(dependent variable) iv. Use language that is precise and relevant to the question

Scientific Skill - Predicting and Hypothesizing

New Brunswick Spotlight on Science Skills: Grade 6 April 2015

GCO: Plan & Perform (PP) Ask questions, make predictions about objects and events and develop fair tests to investigate those questions. Observe and investigate their environment and record the results SCO: PP2 State a prediction and a hypothesis based on an observed pattern of events Scope and Sequence of Outcomes

Grades K-3 Grades 4-6 Grades 7-9

200-3 Make predictions, based on an observed pattern

204-3 State a prediction and a hypothesis based on an observed pattern of events

208-5 State a prediction and a hypothesis based on an observed pattern of events

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? In Grade 6, the term hypothesis is introduced. Hypothesis statements are plausible predictions of a relationship between two variables, supported by information from a student’s current understanding. This understanding could come from a variety of sources such as a previous experiment, a demonstration, research, a television program, or what someone has told them is true. Students will be working during their middle school years with developing hypotheses with the expectation of mastery at high school. A useful hypothesis is a testable statement, which includes a prediction and a supporting reason or explanation. A useful scaffold for writing hypotheses is the “If, then, because” scaffold.

Hypothesis If...then...because

If the (IV) is (describe the change), then the (DV) will (predict the effect), because (state the justification). Independent Variable - (IV) Dependent Variable - (DV) Hypothesis examples:

• If exposure to UV light is increased then more people will get skin cancer, because research shows that people in warmer climates get more skin cancer than people in cold climates. (supported by research)

• If the cones of a tree are pink rather than yellow, then flies will lay more eggs in them, because initial observations seem to show this trend. (supported by observations)

• If salt concentrations in soil are increased then the rate of plant growth will decrease, because plants growing near salt water are smaller. (supported by research or observations)

• If air temperature is reduced, then leaf colour will change, because leaves change colour in the fall when it starts to get cooler. (supported by observations)

Connection to Communication

• Communicate questions, ideas, and intentions, and listen

Students have been using an “If, then, because” scaffold in the elementary grades for writing predictions with a supporting reason. In Grade 6, a hypothesis will be more specific and/or may suggest a more complex investigation than in previous grades. The other change for Grade 6 students is the introduction of the writing of hypotheses in the passive voice. The passive voice reinforces that scientific work is done as objectively as possible. It clearly expresses descriptions and procedures so they can be compared and reproduced. For example:

Grade 3 Grade 4 Grade 5 Grade 6 (passive voice)

If I add fertilizer then the grass will grow bigger, because when my dad added it the flowers they grew big.

If I add fertilizer then the grass will grow taller, because our bean plants with fertilizer grew taller than the others.

If I add fertilizer then the grass will grow taller, because it will give the plants more nutrients that have been shown to support growth.

If the amount of fertilizer is increased then the grass will grow tall faster, because the fertilizer will provide more nutrients that have been shown to support growth.

A hypothesis is a tentative statement, which the results of the investigation will support or not. Students have a tendency to want their hypothesis to be proven correct. Results may be expected or unexpected. The hypothesis is not found to be “wrong”, but rather supported or unsupported. The conclusion will be equally correct whether or not the evidence supports the hypothesis. Furthermore, when the hypothesis is supported, it does not necessarily mean the hypothesis is correct. For example:

Hypothesis

If exposure to UV light is increased then more people will get skin cancer, because research shows that people in warmer climates get more skin cancer than people in cold climates.

-­‐ If supported

One must still consider that factors other than exposure to UV light may be responsible for or contribute to skin cancer.

-­‐ If not supported

There may be more than one factor necessary for skin cancer to occur, such as exposure to skin cancer and genetic predisposition to cancer.

Depending on the context, estimation is a skill that can enhance the ability to make an accurate scientific prediction. Estimation is a strategy for determining approximate values or quantities, usually by referring to benchmarks or using referents, or for determining the reasonableness of calculated values. Based on the grade level standards (cross-curricular with Math), students should use estimation strategies where appropriate.

GCO: Plan & Perform (PP) Ask questions, make predictions about objects and events and develop fair tests to investigate those questions. Observe and investigate their environment and record the results SCO: PP3 Identify major variables to control and test in investigations Scope and Sequence of Outcomes

Grades K-3 Grades 4-6 Grades 7-9

204-4 Define objects and events in their investigations

208-7 Formulate operational definitions of major variables and other aspects of their investigations

204-5 Identify and control major variables in investigations

208-6 Design an experiment and identify major variables

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? Students should understand that variables are predominant in many scientific process skills. The focus of this specific outcome is the identification of variables to ensure a fair test. In practice, a fair test means identical procedures must be performed where only one variable is changed at a time. Students should be able to design a fair test that considers the variables that need to be controlled (kept the same) and the identification of a variable to test (independent) and a variable to measure/observe (dependent). Controlled Variables - the variables that are kept constant or monitored to minimize any effects on the experiment. Independent Variable (IV) - the variable in the experiment that is purposely changed or manipulated, either in quantity or quality, also referred to as the manipulated variable or variable to test. Dependent Variable (DV) - the variable in an experiment that changes in response to the independent variable and, therefore, is also referred to as the responding variable or the variable to measure. The independent and dependent variables are factors in writing a testable question. Example: Initial Scientific Question - “How effective are plant-based insect repellants?”

Independent Variable Possible Dependent Variables

Different brands of plant-based repellents

• total number of insect bites • size of insect bites (mm) • color and/or itchiness of insect bites • length of time they provide protection (min)

Connection to Communication

• Communicate questions, ideas, and intentions, and listen

• Ask others for advice or opinions

• Identify problems as they arise and work cooperatively with others to find solutions

• Same driver • Same pressure is applied to

brake each trial

Achievement Indicators Guiding Questions: • What evidence will I look for to know that learning occurred? • What should students demonstrate to show their understanding of the Scientific Process Skill? Use the following set of indicators as a guide to determine whether students have met the corresponding specific outcome.

i. Distinguish between what is tested, what is measured/observed and what is controlled ii. Identify one independent variable and one dependent variable, with other variables

controlled in investigations iii. Collect evidence relevant to the relationship of the independent and dependent variable

205-8 Identify and use a variety of sources and technologies to gather pertinent information

209-5 Select and integrate information from various print and electronic sources or from several parts of the same source

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? Students should be able to design a plan that they will use to fairly test an initial idea or question in a safe manner. In practice, a fair test means identical procedures must be performed where only one variable is changed at a time. The focus of these outcomes is the planning of steps and experimental design. There are a variety of components that make up experimental design. Requirements of experimental design:

• Identification of needed equipment and materials • Identification of variables (Controls & Independent/Dependent) • Planning a set of steps:

• to test a single question • design minimizes bias • may incorporate multiple trials to increase accuracy • can be repeated by someone else

Connection to Communication

• Communicate procedures and results, using lists, notes in point form, sentences, charts, graphs, drawings, and oral language

• Work with team members to develop and carry out a plan

• Ask others for advice or opinions

• Identify problems as they arise and work cooperatively with others to find solutions

• Ensure safety of self and others

Students are also expected to follow and carry out procedures safely (both teacher-directed and student-designed) using appropriate materials and tools effectively. Bias Holding a scientific bias means to unfairly favour one variable against another. In order for a test to be deemed fair, it must be done in a way that eliminates one variable having an advantage. Identical procedures must be uniformly performed. For example, every time you release your paper airplane, it’s uniformly performed, regardless of the type of paper used. Multiple Trials It is often important to perform multiple trials of an experiment to ensure that the results are accurate, reliable, and reproducible. If the variable was accidentally changed in the first trial, this becomes obvious in the following trials and can be corrected in future trials. The number of trials required depends on the amount of time to conduct the experiment and the nature of the task. Achievement Indicators Guiding Questions: • What evidence will I look for to know that learning occurred? • What should students demonstrate to show their understanding of the Scientific Process Skill? Use the following set of indicators as a guide to determine whether students have met the corresponding specific outcome.

i. Plan procedures with a set of steps to test a single question ii. Plan procedures to minimize experimental bias iii. Plan procedures to use multiple trials to increase accuracy, if appropriate iv. Plan procedures with enough detail they can be repeated by someone else v. Plan procedures identifying needed equipment and materials vi.

Scientific Skill - Collecting and Recording Data

New Brunswick Spotlight on Science Skills: Grade 6 April 2015

GCO: Plan & Perform (PP) Ask questions, make predictions about objects and events and develop fair tests to investigate those questions. Observe and investigate their environment and record the results SCO: PP5 Recording observations and collecting relevant data Scope and Sequence of Outcomes

Grades K-3 Grades 4-6 Grades 7-9

201-4 Observe, using one or a combination of the senses

205-5 Make observations and collect information relevant to a given question or problem 209-4 Organize data, using a

format that is appropriate to the task or experiment

201-5 Make and record relevant observations and measurements, using written language, pictures, and charts

205-7 Record observations using a single word, notes in point form, sentences, and simple diagrams and charts

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? The focus of this section is that students are able to record all relevant information measured (Quantitative) and observed (Qualitative) in a format appropriate to the type of data. Qualitative data describes whereas quantitative data defines. The dependent variable will determine the type of data collected. Students are expected to accurately record what is observed even when results differ from what is expected. Results are never right or wrong, but only expected or unexpected. Unexpected results still convey important information. Quantitative Data - Data that can be measured, numbers with unit of measurement are recorded. Examples include: length, height, area, volume, weight, speed, time, temperature, humidity, sound level, cost, age, and so on. Students should understand that they must accurately use scientific devices and equipment. In Grade 6, when variables are measured, accurate measurement is important. Qualitative Data - Data that can be observed but not measured. It usually describes characteristics or qualities. Examples include: colour, odour, texture, appearance, or data that is described by category (e.g., the colour of the sky) Students should be able to distinguish their observations from making an inference. Observations require you to use one or more of your five senses to notice or determine something. Inferences are statements that combine observations with other knowledge. For example: you see steam rising from a cup of coffee

Ø “steam is rising from the cup of coffee” (observation) Ø “the coffee is hot” (inference).

Connection to Communication

210-2 Compile and display data, by hand or computer, in a variety of formats, including diagrams, flow charts, tables, bar graphs, line graphs, and scatter plots

210-3 Identify strengths and weaknesses of different methods of collecting and displaying data

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? This outcome is about organizing information after data collection. Organizing qualitative information: students need to be able to identify and classify according to attributes. The classification requires students to use sorting rules consistent with math standards. “In Grade 2, students need to build on their prior experiences to sort objects and shapes using two attributes. If students find it difficult to sort by two attributes at the same time, they may find it helpful to sort by one attribute and combine two of the sorted groups.” (NB Mathematics Grade 2 Curriculum, p.70) In Grade 6, students need to be able to identify important characteristics that distinguish or are in common across a variety of items or organisms. It is expected that this information would be organized and displayed (e.g., Venn diagram).

Connection to Communication

• Communicate procedures and results, using lists, notes in point form, sentences, charts, graphs, drawings, and oral language

• Work with group members to evaluate

Organizing quantitative data: students need to be able to take quantitative data and display it in an appropriate format. The focus is taking raw data and creating charts or graphs that are appropriate to the task. Please refer to Math curriculum and the standards expected at each level. Note that the distinction between discrete and continuous data is often overlooked. Grade 3 Math Standard Single Bar Graph

Grade 5 Math Standard Double Bar Graph

Grade 6 Math Standard Line Graph

“The purpose of a line graph is to focus on trends implicit in the data…the distinction between continuous and discrete data should be emphasized as students investigate line graphs. Continuous data includes an infinite number of values between two points and is shown by joining the data points. Discrete data has finite values (i.e., data that can be counted such as the number of pets), and the data between the points have no value. As a result the points in the graph should not be connected and no inferences can be made about values between two data points” (NB Mathematics Grade 6 Curriculum, pg. 94)

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? This outcome is asking students to analyze data. Interpreting data is a critical-thinking process used by scientific researchers to review the data gathered in the course of an investigation. Drawing conclusions is a separate outcome though it is expected that they would be learned together. At Grade 6, students should be able to identify and explain patterns/trends in data. Students are expected to suggest a reasonable explanation(s) noting possible sources of error. Students should be able to describe the relationship the pattern/trend indicates. Interpreting data involves sorting it into useful arrangements, looking for similarities and differences, thinking about missing data or errors, and summarizing what the data might mean. Appropriate description: The population of New Brunswick increased until 1996 and then decreased slightly. Not acceptable descriptions: The population went up and then it went down. – Lacks detail in description

It started out steep, then it got flatter. – Vague language Overall the population went up. – Oversimplification Also, regardless of the type of data, students should be able to identify a discrepancy within the data. A discrepancy is a value or observation that deviates from the standard or norm. Discrepant data do not fall within the observed pattern.

202-7 Propose an answer to an initial question or problem and draw a simple conclusion based on observations or research

206-5 Draw a conclusion, based on evidence gathered through research and observation, that answers an initial question

210-11 State a conclusion, based on experimental data, and explain how evidence gathered supports or refutes an initial idea

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? Students should use information from readings, from previous learning, prior knowledge, and from evidence gained through investigation to draw conclusions. To make simple conclusions means that students are able make a statement based upon logic and the evidence available. Whether the prediction/hypothesis is supported or refuted is not a measure of success or failure since scientific knowledge is advanced by either result. Where possible students should compare the results of their investigation to those of others, recognize that results may vary and explain why. Comparison of findings to those of similar investigations can add weight to the conclusion. The conclusion: • will be framed around the initial question that was tested. As the student analyzes the data

it is important to ask the question: Did the change (independent variable) made cause the effect that was measured (dependent variable)?

• must either confirm, deny, or acknowledge uncertainty about the relationship between the two variables. The prediction/hypothesis may be supported or refuted based on the data.

• may comment on whether the investigation was a fair test and suggest improvements to experimental design.

Elaboration Guiding Questions: • What do I want my students to learn? • What do I want my students to understand and be able to do? Applications of Learning components involve higher order thinking type activities. Depending on the task, this can take different forms. The overall theme is that students are discussing and reflecting: • evaluating sources of information • evaluating the fairness of an experimental design • evaluating the usefulness of a constructed design • applying conclusions reached to real world scenarios • extending those initial ideas by creating new questions to test • evaluating their own/other’s thinking and explanation in terms of plausibility and scientific

evidence Students should be engaged in metacognition which is, put simply, thinking about one’s thinking. The burden of learning does not fall on the teacher alone. Students need to be aware
