In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

In this laboratory activity, learners use a simple procedure to bait oomycetes from water and/ or soil and then examine these fungus-like organisms with the microscope to see how they look.

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

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this hands-on nature activity, learners observe the emergence of leaves and flowers. Branches from trees and bushes are collected in the early spring, brought indoors, and placed in water.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
