Hooked on Science: Valentine candy drop

Materials

• Valentine's Day chocolate candy
• Water
• Transparent container

Instructions

• STEP 1: Fill the container half of the way with water. Is the water a solid or a liquid, and why? Describe the water by using its observable properties.
• STEP 2: Is the Valentine's Day chocolate candy a solid or a liquid, and why? Describe the candy by using its observable properties.
• STEP 3: Drop the candy into the water and observe. What happened? Develop a model to describe how the candy that floats is made of particles too small to be seen.

Explanation

Most of the candy will be denser than the water and sink to the bottom of the container. Some of the candy will be less dense when compared to the water and float. Each piece of candy contains different ingredients. Those pieces with a lot of air inside float.
