2014 - 2015

Activity .5: Sept. 3, 2014

Getting Started: Write 2 – 3 things that you think would keep science class safe.

Procedure:

1) Review the science lab rules with the class 2) Form a team of two and think of a science rule that you would like to illustrate as a team.3) Review the rubric for your first science grade.3) Check in with Mr. Forde to get the OK to get started on a rule to create.4) Start creating the poster that you will present tomorrow!

Homework…. Have the science safety contract signed and returned by tomorrow!

Let’s Save Poor Fred!

Activity 1: Saving FredSept. 8, 2014

Getting Started: Write 2 - 3 sentences describing problem you solved revently and how you solved it

Introduction: Read and summarize pg. A-4 in one sentence.

Key Words: Hypothesis, Scientific Method

Procedure: Write a procedure for SAVING FRED with your partners and complete it for HW on Monday 9/8.

Homework for Tuesday 9/9: Answer Analysis Questions 1 – 4 on page A6 – A7.

Reflection: People face problems in their lives every day. What did you learn from this activity that you can use to solve other problems? How do you think this compares with how scientists solve problems?

Activity 2: The Pellagra StorySeptember 9/10, 2013

Getting Started: List 2 things that scientists could do to learn more about a disease and its cause or causes?

Introduction: We read the intro.

Challenge: What are the common elements of all scientific problem-solving methods?

Key Words: ethics, evidence, inference, observation

Results: See Worksheets Fill in “Notes on the Pellagra Story” sheet Complete “Observation and Inference” sheet Compare “Dr. Goldberger and the Traditional Scientific Method’

<<Video Link -- http://www.pbslearningmedia.org/resource/odys08.sci.life.gen.pellagra/pellagra/>>

Analysis: Answer Analysis Questions 1a, 1b, 2a, (homework)

Reflection: Choose two careers that interest you (police officer, nurse, teacher, scientist, etc.) and describe the kids of problems they face in their careers and how they solve them.

Hypothesis: An educated guess

Scientific Method: Steps that scientists use to complete their work.

Ethics: Looking at what is right and wrong

Evidence: Info that is collected to see if something is true.

Inference: A conclusion based on evidence

Observation: Looking at something carefully.

Key Words:

Should a prisoner who participated in Dr. Goldberger’s experiment on Pallegra be allowed to be released

from prison?

Activity 5: Can you feel the difference?September

Getting Started: Discuss designing an experiment. (Watch PBS Video- http://pbskids.org/dragonflytv/show/basketball.html)

Introduction: Read and summarize pg. A-20 in one/two sentences.

Challenge: What is the smallest distance apart at which you can still feel two points?

Sensitivity:

Key Words:

Analysis: Answer Analysis Questions 1, 3, 4a, 4b and 6.

Reflection: How would you create an experiment to test a person’s sensitivity to sound?

Activity 5: Paper Shots

Getting Started: Discussion “How would you design a basketball shooting experiment?” (Watch PBS Video- http://pbskids.org/dragonflytv/show/basketball.html)

Challenge: What are the variables of a well designed experiment?

Key Words: Control Variable, Dependent Variable, Independent Variable

Procedure: Each student shoots a paper ball 5x at 3, 6, 9,and 12 tiles to collect data.

3 tiles 6 tiles 9 tiles 12 tiles

Data Table:

1 meter shot 2 meter shot 3 meter shot

Class Data:

Control Variable- Those things you keep the same in an experiment.

Dependent Variable- D = data, Data you are collecting in your experiment.

Independent Variable- The change you are making (studying) in an experiment.

Activity 6: Finding the NerveSeptember 16, 2013

Getting Started: What and where are your 5 senses?

Challenge: Why do different parts of the body have different sensitivities to touch?

Key Words: Homeostasis, Nerves, Nervous System, Neuron,

Procedure: Let’s read together. You will complete the stopping to think questions at each section in your binder.

Analysis: Answer Analysis Questions 1 - 4

Nerves – a bundle of nerve cells

Neuron- a nerve cell Nervous System- Your brain, spinal cord and nerves.

Homeostasis- the ability to maintain a steady environment.
