Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.
In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.
Learners are given mysterious white powders and have to determine their identity with chemical tests.
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.
In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.
In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.
In this activity on page 3 of the PDF, learners discover how science and Halloween are fun companions as they make paper bleed.
This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.
In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.
In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre
Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.
In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e
In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.
