In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

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

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

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

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

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