Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Why do scientists use models? In the first installment of 22, groups create scale models of our solar system. They then share and discuss their models.

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...

Students investigate the structure of the atom through hands on activities. In this atomic structure lesson, students perform 4 activities showing indirect evidence of the structure of the atom and the parts of the atom. They also list...

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

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 study hydrocarbon gases and chemical equations. In this hydrocarbon gases lesson, students work in groups complete a molecular formula worksheet and review alkane prefixes. Students complete molecular models, balance chemical...

Students analyze a variety of cooking oils to determine the amount and types of fats included in each.
