Chemical Reactions - Borax & Glue, Cream
Fifth graders, in groups, complete two activities in which various substances are combined, resulting in a very different substances. They discuss reactants and products and chemical reactions.
Curated OER
Chemical Change
Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

Activity #9 Tye Green Blob
Students comprehend that a chemcial change produce substances with a different composition and physical and chemcial properties. They state the differences between physical and chemical changes. Pupils observe changes that occur during...
Curated OER
It is a Crash Test, Dummy
Students research air bags on the Internet and use the information to design their own version of an air bag. After exploring the benefits and dangers of air bags students perform a chemistry lab in which they mix baking soda and vinegar...

Chemical Change and Physical Change
Sixth graders combine chemicals to create a chemical change. In this chemicals lesson plan, 6th graders will investigate characteristics of chemical change by combining chemicals. They will learn that color change is an indicator of...
Curated OER
It's a Crash Test, Dummy
Students use the internet to research air bags in cars and trucks. In groups, they discover air bags history and the safety issues surrounding them. They create their own design of a new air bag and test it using a raw egg in...
