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 explore motion, energy, and electricity by constructing bottle cars that run on motors.

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 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 fun group activity involving music and movement, learners are introduced to the idea that many insects walk by using their legs to create "alternating triangles." Learners sing the "Ants Go Ma

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 are challenged to design and build a miniature tree house in a potted plant. This activity uses engineering concepts to encourage creativity.

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.

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 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.
