In this activity, learners will explore globes of frozen water to learn how to ask and then answer 'investigable' questions. The activity web page includes a short video demonstration.

In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

In this outdoor activity, learners discover the wonders of the habitat surrounding them.

In this outdoor activity linking human health to the environment, learners use their pulse rates as a measure of the effort expended in walking on different slopes.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

Learn about friction and kinetic energy with this cool spinning toy.

In this outdoor winter activity, learners search for and create hibernation sites that will protect gelatin "animals" from freezing.

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

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

During this interactive "survival" game, students learn about the importance of camouflage and how it helps animals to blend into their surroundings, as either predator or prey.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit

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

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

Data in computers is stored and transmitted as a series of zeros and ones. Learners explore how to represent numbers using just these two symbols, through a binary system of cards.

In this activity, learners will be working with a sort of scientific magic, capillary action! They will set up 3 cups of water of different colors, connect them with paper towels and wait.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.
