Mixtures
Sixth graders experiment with mixtures. In this chemistry lesson plan, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.
Curated OER
The pH scale
Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.
