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

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

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 optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this activity about light and perception, learners create pictures in thin air.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

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 explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

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

This activity is about collecting and analyzing DNA as part of a criminal investigation.

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 activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
