In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.

In this challenge, learners figure out how to make a juice stain disappear.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity, learners create a colorful foam fountain by adding yeast to a chemical reaction. This activity introduces chemical reactions to young learners and teaches the concept of catalysts.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

Learners write an invisible message using lemon juice on a piece of paper. They then develop the message by soaking the paper in a dilute iodine solution.

In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity, learners explore materials through paper chromatography.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity, learners discover that atoms and ions of different metals will change places.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.
