#### Presentation Transcript

Scientific Method

### 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!

Observation of unfortunate death

Observations:

### 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.

3 sentence format

I think…

I think this because I observed…

### 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

Your paper should look like this…

Hypothesis or nah?

YesNo

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

### 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

• 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

Types of Variables

IndependentDependent

Do NOT glue until you’ve been checked off!

Warm up

What is the independent variable in this graph? The dependent?
