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, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
