Paint Property Experiments
Students identify various kinds of paints by using the scientific method. In this solvents lesson students collect data and identify paint samples while working in teams.
Curated OER
Mixtures
Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.
