Get all wrapped up in a lesson about skin!

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this outdoor activity, learners design devices that will catch prey or gather plants.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one
