In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

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.

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.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

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

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.
