In this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth.

In this activity, learners are challenged to design and construct a jointed figure that moves in a motion (something like jumping jacks) when a string is pulled.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Historically, sea floor mapping (bathymetry) was done by soundings.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.

In this activity, learners will build a ball run contraption.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
