Learners are given mysterious white powders and have to determine their identity with chemical tests.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this chemistry demonstration, acid rain is simulated in a petri dish.

Learners pour equal amounts of coffee, mineral oil, corn syrup, and alcohol into a beaker. The liquids resolve into stacked layers, and learners can infer which liquids are the most and least dense.

In this activity, learners perform a simulated blood test procedure.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.
