In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre

In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this outdoor activity, learners turn the fun of feeding wild birds into an investigation of bird behavior.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

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 explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

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 outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.

In this activity, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

In this activity, learners explore the different salinities of various sources of water by taste-testing.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o
