V-Lab Middle School Program and Experiments
Middle School (6th – 8th grade)
- CO2 to the Rescue! Using a chemical reaction to save a cell phone. – This lesson begins with a design challenge: to invent a small device that could rescue a cell phone that accidentally falls into water. A self-inflating balloon might be able to act as a flotation device to keep a cell phone from sinking or bring it up after it sinks. Students conduct a pair of chemical reactions to determine which of two acids react with baking soda to produce the most carbon dioxide gas and apply this to the flotation problem.
- Density Rainbow – Students will investigate the concept of density by creating a rainbow in a tube using sugar water solutions. We will define density (density = mass / volume) and construct a tower with colored sugar water solutions to make a rainbow. They learn about pipetting and dilutions while making their 0-60% sugar solutions.
- Mystery of M&Ms – Students will answer the question, “What happens when colored candies are placed in water?” We will conduct experiments on M&M and Skittles looking at the diffusion of pigments and sugar in water.
