Bellringer: share out

1. A doctor wants to know if eating carrots improves your vision. He gets 50 of his patients to eat raw carrots every night before dinner, and 50 of them to continue with their regular diet. He then tests their vision after 2 months.

a. What was the one thing that the doctor changed between the 2 groups of people?

b. What would happen if one of the groups of people happened to be a lot older than the other group? How would this affect the doctor’s results?

CITE evidence

What is a variable?

• A variable is anything that changes in a scientific experiment

Example

The Question: Ms. Rekart’s class wants to know… does smell affect how well you can taste?

Their hypothesis:

3. Their experiment: They decide to pick a volunteer from the class, ________________, to try to guess the color of skittles with his/her eyes closed! First, he/she will try with his/her nose plugged---then, he/she will get to use smell! They will then see if smell affected taste.

RED GREEN YELLOW ORANGE PURPLE

WITH SMELL

WITHOUT SMELL

What kinds of variables are there?

• There are 3 types of variables: independent, dependent, and control.– The independent variable is the one that changes

first, or the one that you change.

In our experiment, what was the independent variable?

– The dependent variable depends on the independent variable

In our experiment, what was the dependent variable? ______________________

– The control variable(s) are things that we try to keep the same.

What stayed the same between the two tests?

Practice

1. Jose wants to know if feeding his puppies expensive food will make them fatter. He gets 2 identical puppies and feeds one expensive food and one regular food.

What is the independent variable: ____________________________What is the dependent variable: ____________________________What is/are the control variable(s):

A scientist wants to know how the type of light affects the height of a plant. She gets 2 bean plants and gives one direct sunlight and one artificial light.

What is the independent variable: _____________________________What is the dependent variable: ____________________________What is/are the control variable(s):

How do we graph variables?

• The independent variable always goes on the X-axis (the bottom of the graph)

• The dependent variable goes on the Y-axis (the side of the graph)

Example: Let’s graph our skittles experiment!
