This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

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

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve 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 activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.

Using simple, inexpensive items, learners build and test submarine models.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

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 you'll see how the sun's tilt on its axis changes the length of shadows. For example, why is your shadow longer in winter than in summer?

In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.

In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
