In this activity, learners build a plastic emergence chamber (or use purchased "mini mosquito breeder") to observe and analyze the mosquito life cycle.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

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 activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

In this activity, learners stain fabrics--on purpose!

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
