Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners use simple materials to create giant bubbles.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In the kitchen, learners can perform their own density investigation.

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

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.
