Inquiry Lab

What are some things we could change?

• Temperature of milk• Milk type• Soap type• No soap

What effect can we measure?

• Distance • Speed• Level color drops• How long it moves

Decide on the variables

control

• 2% milk• Color• Soap

change measure

Temperature

Independent variable(change)

Distance

Dependant Variable

(measure)

Constants

• Things you would keep the same– Beaker– Amount of milk– Toothpick– Drops of color

Problem

• Write a question must include both Independent and Dependant variable.

• Example: How does increasing the temperature of the milk affect the distance the color will travel?

Hypothesis

• If I change the temperature from room temperature to 80’

• Then the drops will move away from each other farther.

Procedure

• List materials• Write in Steps• Must include how data is recorded• Describe Control set up• At least 100 trials human, 50 trials animals, 30
