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

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.

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

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

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, 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, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity (located on page 2 of PDF), learners explore alternative uses of a simple paper cup, dubbed a "mystery item." Learners act as detectives and explore the properties and functions of th

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.

In this activity, learners build small animated toys that move.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners will keep track of how much they can do in one minute. Instructors can pick something everyone will do for a minute, such as jumping up and down or drawing stars.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.
