In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
