In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

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

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

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

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 science/art activity, learners create an insignia or emblem for a planet exploration mission.

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 activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

This is a series of demonstrations about different electrical and magnetic phenomena.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

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.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!
