In Ms. Cortrino’s classroom experiment, students investigate which types of candy float in water. The hypothesis suggests that candies made primarily of air, such as marshmallows, will float due to their low density. The materials include various candies—hard candies, truffles, and more—observed by dropping them into water-filled bowls. Through multiple trials, students record whether each candy sinks or floats, analyzing results to understand the concepts of density and buoyancy. The experiment concludes that air-filled candies indeed float, confirming the initial hypothesis.

Which candy will float Problem: What are you trying to find out?
Hypothesis: What do you think will happen? If I place different types of candy in water, then I think the ones made of marshmallows will float because they are made mostly of air. Students in the classroom
Materials: What objects will you use? • hard candies, • conversation hearts, • truffles, • Babyruth • Caramel hearth • Blow pop • Bowls and cups with water • Various candies, such as: • Whoppers, • Kit Kat bars, • marshmallows, • chocolate hearts, • Reese’s,
Procedure: What steps will you take to find out? • Drop the candy in the water. • Watch what happens: Does it sink or float? Record Data/Results • Multiple trials
Variables: What thing did you change? I changed the types of candies I placed in the water. Constants: What things stayed the same? The things that stayed the same were the amount of water and the containers.
Results/Data: What happened? Float Sink
Results/Data: What happened?
Conclusion: What did you learn? Was your hypothesis correct? We learned that candy made mostly of air will float.
