Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...

Students create models of ionic and covalent electronic bonds to demonstrate their understanding of these chemistry concepts. They explain how both ionic bonds and covalent bonds work so that younger students can understand.

Students demonstrate their understanding of a chemical process.  In this exploratory lesson students create a clay animation that shows how a specific type of chemical bond. 

Students investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Students conduct a series of experiments to explore carbon dioxide properties. In this chemistry activity, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.
