" Can an over inflated football be thrown farther than a football that has the normal amount of air?

Identify

-independent variable

-Dependent variable

-Control AND experimental groups 

IV-over inflated football vs regularly inflated football

DV- Distance thrown

-Control: Regular inflated football

Experimental: Over inflated football

400

What axis does the independent variable go on? How about the dependent variable?

IV- x axis

DV y axis

How could you test this scenario?

"Will hair be softer with mayonnaise or conditioner?

PLEASE WRITE OUT YOUR PROCEDURE!

answers will vary

6 steps of the scientific method

1. Ask a question

2.Do research

3.Create a hypothosis

4.Test a hypothosis 

5.analyze the data

6. conclude

" Can an over inflated football be thrown farther than a football that has the normal amount of air?

Write a hypothesis

if you inflate a football the normal amount then it will go further

A team of scientists want to test if watching commercials makes kids eat more snacks when watching TV.  They gather two groups of elementary school students.  The first group watches 2 hours of TV with no food commercials.  The second group watches 2 hours of TV with food commercials every 15 minutes.  After the scientists record how many goldfish the students ate during the time period.

List the independent variable, dependent variable, control group, and experimental group. 

IV = whether or not kids watch food commercials

DV = amount of goldfish eaten

Control group = group without food commercials

Experimental group = group with food commercials
