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

In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

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.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

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

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

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

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

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.

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.

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

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.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

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 use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.

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