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 group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

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

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 math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

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.

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake

In this activity about neuron/target muscle recognition (page 44 of the PDF), learners arranged in two rows facing away from each other use string to simulate neural development.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this simulation activity, learners will raise a pack of wolves under ten different conditions: without human interference and with human interference.

In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
