Chemical Bonding
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...
Curated OER
Heat, Temperature, and Transfer
Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...
Curated OER
Observations & Chemical Reactions
Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...
