Chemistry
In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...
Curated OER
Oxidation and Salt
Students study the reaction on iron in water, air, and sodium chloride. They create a situation that shows this process and gives them the opportunity to hypothesize what, why, and how. They keep records and do an oral and written ...
