Review states of matter and explore the law of conservation of matter as well as physical and chemical changes with this root beer float lab.
Students measure the parts of the float as they create it to show that the mass stays the same. They also discuss whether a physical or chemical change is happening.
This lab uses the 5E method (engage, explore, explain, extend, evaluate) and includes step by step directions along with a student lab sheet. The lab sheet is 2 pages and there are 9 pages of detailed teacher directions.
The lab takes 45 minutes to an hour to complete.
