In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

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

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity, learners will explore acid-base reactions and create their own bubbly results.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners take apart a used zinc-carbon dry cell battery.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

This quiz lets you estimate your annual radiation exposure.

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

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners will observe a deceptively simple process: a burning candle.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.
