step 1 observe
Step 1: Observe
  • Before you start to do, you need to observe! This is critical when it comes to creating your hypothesis.
  • Observe with 4 senses (eyes, ears, nose, touch). We do not taste anything in science!

Your paper should look like…

things to look for
Things to look for…
  • What type of shoe prints are there?
  • What is the spacing of the prints?
  • What is around the pig?
  • Is there anything else that you notice?
  • Do you smell anything?

-Look at your observations and decide what you think happened to the pig.

-You must site evidence from your observations!

-Complete sentences, please. 3 sentence minimum.

slide6

3 sentence format

I think…

I think this because I observed…

step 2 hypothesis
Step 2: Hypothesis
  • Educated guess based on observations.
  • It does not have to be in the form of “if…then…”
  • I want the hypothesis to be a complete sentence explaining what you think will happen during the experiment based on observations made.
  • Hypothesis sorting activity
slide8

Your paper should look like this…

Hypothesis or nah?

Yes No

Do not glue until you have been checked off!!!!!!

step 3 create the experiment
Step 3: Create the experiment
  • You will need the process of how you will test your hypothesis
  • You will need an independent variable, a dependent, and a control before you create the process of the experiement
types of variables
Types of Variables
  • Independent Variable: What YOU change/control to test your hypothesis
  • Dependent Variable: What changes BECAUSE OF the independent variable
  • Control: What stays the same throughout the entire experiment

Your paper should look like….
