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.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.
