Question: Does pressure affect the amount of ice?
 What is the independent variable (what am “I” as the scientist
changing? What is different between the control & experimental
groups?
 What is the dependent variable? What are you measuring?
 What are the constants? What has to be the same between the two
groups?

Claim: Circle the claim you believe the evidence supports.
1) Pressure affects the amount of ice – there is less ice after pressure is
applied compared to the control group
OR
2) Pressure does NOT affect the amount of ice – there is the same
amount of ice when pressure is applied compared to the control
group.
Evidence: Look at your data table. Circle the boxes that have the best
evidence to support the claim you chose.
Now, use that data to write a sentence or two stating this evidence in
words.

Reasoning: (This is where you explain why using science ). According to
our research, pressure lowers the melting point. My research supports OR
does NOT support this (circle).
