Students classify compounds as ionic or covalent. In this chemical bonding lesson plan, students experiment with 6 chemical compounds. They test physical properties such as the melting point, the solubility and the electrical...

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...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.
