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 activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

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

In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

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 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, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

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 multi-part activity learners examine non-point water pollution.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

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

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

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 test soil content using their sample, some water and a container that seals.

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

In this activity, learners will pretend to be archaeologist using this chilling experience.
