In this activity, learners build a carousel toy that spins when pushed down.

In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

Learners use shop tools and various materials to construct a magnetic spinner and a compass.

In this activity, learners discover that some things only stand up while they are spinning.

In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

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
