During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

The radical reactions of polymers seems abstract to many pupils, but this instructional activity turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and...

To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several...

Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Scientists work every day to find solutions to genetic diseases. Scholars learn about the process of gene sequencing, mutations, and the results. They explore genetic diseases and therapies to intervene and help and, through case...
