Conservation of Mass

Blast off! An engaging hands-on activity has pupils create rockets powered by Alka-Seltzer. They learn about the physics behind these rockets throughout the process.

Study corrosion on bronze statues with a hands-on lesson. As pupils place a penny in water with salt, they observe the changes in the penny throughout a period of a week. They then analyze the pre-conservation and the...

Does matter ever just go away? Find out with this entertaining video that dives into a sweet investigation that involves cake and sweet drinks! Super scientists gain insight about the physical changes from chemical reactions and...

Get your blocks out! It's time to start building and learning about mass! Enthusiastic chemists get in-depth information about the conservation of mass and the way it applies to chemical changes. 

Thinking back to the last time you taught a lesson on chemical changes ... was there no reaction? Check out an explosive video to put some spark back in your instruction! The narrator of the video guides you through the...

Students investigate chemical reactions. In this chemistry lesson, students burn magnesium and record the mass. Students list five chemical reactions they see everyday.

In this episode of Crash Course Kids, the host chats about chemical reactions and the conservation of matter. [3:52]

For this experiment for Grade Five, students develop an understanding that chemical changes in matter do not affect the actual mass of the matter.

This site provides a great overview of stoichiometry, the part of chemistry that studies amounts of substances that are involved in reactions. Content focuses on what you measure, and includes two examples.

Students perform an experiment to show the chemical reactions that occur when metal corrodes. They apply the results of the experiment to the conservation efforts of art curators trying to restore an ancient Greek bronze. This lesson...
