In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

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

In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

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

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

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.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

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

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this archaeology activity, learners make observations and conduct an experiment to demonstrate the effect saltwater has on artifacts.

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

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

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.

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