2 FUN WITH FOIL
Question: Does the shape of an object affect its density?
Objective: Using aluminum foil, demonstrate how density can be affected by the shape of an object. You must make an
object that is positively buoyant, negatively buoyant, and neutrally buoyant.
Observations:
Buoyancy
Description of your objects’ shapes
Positively Buoyant
Negatively Buoyant
Neutrally Buoyant
Claim: Make a claim about the shape of an object and its density based on your results.
Conclusion: Support your claim using your observations and scientific fact.

3 AN “EGGCELLENT” LAB
Question: Is salt water denser than fresh water?
Objective: Observe the effect of fresh water and salt water on the buoyancy of an egg.
Hypothesis: Will the difference in water affect how the egg floats or sinks?
Observation: Write a sentence that describes what happens when an egg is placed in fresh water. Write another
sentence that describes what happens when an egg is placed in salt water.
Claim: Make a claim about the density of the salt water and the egg based on the observation that you made.
Conclusion: Support your claim using the observations you made as well as scientific fact.

4 LAYERING LIQUIDS LAB
Question: How does density affect the buoyancy of liquids?
Objective: Calculate the density of three separate liquids. Observe how density affects their buoyancy.
Hypothesis: If mixed together, how will vegetable oil, corn syrup, and water layer?
Observation:
Fill in the table:
Liquid
Mass (g)
Volume (mL)
Water
Oil
Syrup
Complete the diagram to illustrate how the liquids layer in a container.
Conclusion: Support your claim using the observations you made as well as scientific fact.
