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...

Host an exciting lab in which learners burn fruit rinds to better understand hydrocarbons. A reading passage and analysis questions wrap up the lesson. 

Which compounds have only one valence bond, and which have two? Chemistry classes sort cards into groups of monovalent and polyvalent piles, according to their bonds. There are 20 cards to identify; half of them name the compound, while...

Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Test your knowledge of Chemistry. Complete the diagram by dragging the labels to the correct location.

Expand your knowledge of Chemistry. Observe how ionic compounds are networks of electrically charged atoms.

A short assessment to see if you understand valence electrons in specific elements.
