In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

Using household materials, learners can make white gooey globs from clear solutions. Alum, dissolved in water, reacts with the hydroxide in ammonia to create aluminum hydroxide.

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

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

In two separate bags, learners mix water with Epsom salts and detergent.

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 activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).

In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).

In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.

Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.
