In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

This is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.

In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.
