In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.
