In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

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.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

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 explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

In this activity, learners investigate the effect of heat on a reaction.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

In this activity, young learners will model land and water on the Earth's surface to make a unique piece of "Earth Art." Activity includes materials list, step-by-step instructions, STEM connections a

In this activity, learners will explore surface tension, what it is, and how we can change it.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this activity, learners will explore saturated solutions and discover how crystals form.
