about the real world.

Take notes by writing what’s in RED

What is the point of today?

To write a testable question.

2. This class

3. LIFE

What does it mean for something to be testable?

Think about the words:- understandable- doable- recognizable-Measureable

Question…

• What we want answered from an experiment

• Always ends in a question mark (?).

• For example:

What is the effect of exercise on body temperature?

Good ways to begin science questions

• What factors cause…?

• What are effects of…?

A ‘quality’ hypothesis…

1. It is an educated guess to a question.

Based on facts and your thoughts

2. We can show it is right or wrong by

doing a TEST.

3. If ___cause____, then __effect___

Is this a ‘quality’ hypothesis?

• Observation: Students are late to class.

• Question: What are the effects of being late to class?

Hypothesis: IF students are late to class, THEN they will receive a lower grade on their daily quizzes.

It’s Demo Time!Chicken Liver…

I noticed that when you put chicken liver into hydrogen peroxide…

Observation?

So I asked “what will be the effect of adding heat to the mixture?”

Procedure

1. Measure 75 mL of hydrogen peroxide using a graduated cylinder.

2. Pour the hydrogen peroxide into the Erlenmeyer flask.

3. Use the tongs to place a piece of chicken liver in the hydrogen peroxide.

4. Light a wooden stick and then blow it out.5. Place the wooden stick into the Erlenmeyer

flask.6. Clean up!

Hypothesis

• Take a min to write your own

• Remember, a quality hypothesis does not have to be right!

Finish 7 + 8

• May discuss with group

Practice!

• Try to write your own hypotheses

• After #1, check with partner

-Explain why observations are important

- Write detailed observations -Make inferences

Today I will be able to…

Key Point 1: An observation is

• Gathering and collecting information (data) using your five senses and tools– Sight– Touch– Hear– Smell– Ruler– thermometer

• Ex: I taste that chocolate is sweet

Key Point 2:An inference

is an interpretation of your observationsEx: I think this is a snickers because it tastes like chocolate and peanuts

The Difference

• Key Point #3: Observations are facts, and can’t be wrong. Inferences are beliefs, and can be wrong.

• Example:–Michael leaves the movie theatre, and

sees that the ground is wet. So Michael thinks that it rained.

“Beyonce looksgood”

• Observation or inference?

“Beyonce looksgood”

• Not an observation!!!– It is not a fact that

Beyonce looks good. – Some people disagree.

• This is an inference!!!– Whoever said this

believes that Beyonce is attractive because of facts: she has clear skin, shiny hair, an hourglass figure, etc.

Observation or Inference? Part I

• This kid looks like a dork.

• The cowboy hat is brown.

• Cake tastes delicious.

• The bandana is red.

• I believe it is his birthday.

Partner Up

• Partners take turns answering

• Classify and explain why

• If your partner doesn’t explain why, ask them!

• If you disagree, you may ask your group

• If the whole group disagrees, all raise hands

Observation or Inference? Part I

• This kid looks like a dork.

• The cowboy hat is brown.

• Cake tastes delicious.

• The bandana is red.

• I believe it is his birthday.

Observation or Inference? Part II

• Make five observations about the classroom, and three inferences based on those observations.

Observations Inferences

1. 1.

2. 2.

3. 3.

4.

5.

Observation or Inference? Part III

• Partner up!

• Take turns with your partner

• Read off an observation or inference

• Partner must classify

• Write down good examples from your partner

Key Point Wrap-up#1: An observation is gathering

information about the world through our five senses and tools

#2: An inference is an interpretation of an observation

#3: Observations are facts, and can’t be wrong. Inferences are beliefs, and can be wrong.
