How do we affect the ecosystem, and what can we do to preserve it? Pupils explore chemicals that promote and inhibit plant growth, then discuss the importance of nitrogen and phosphorus to the survival of organisms and describe how...

Every muscle movement requires energy, but where does that energy come from? Scholars answer this question and more as they complete a worksheet. By following the directions, completing research, and discussing it as a class, they begin...

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

Areas that previously included no risk of Lyme disease now have cases every year. Scholars learn about the spread of Lyme disease and the relationship with ecological succession. Then, they discuss possible solutions using the known food...

Divide your school gym into breeding grounds and non-breeding grounds so that your zoologists can play a game simulating the seasonal migration of shorebirds. Players pick one of the included game cards and follow its directions, which...

How do doctors fight a virus that's constantly mutating? Show science scholars how we fight HIV using one of its own most fundamental processes through a thoughtful demonstration. The lesson focuses on how protease inhibitors prevent HIV...

How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...

How do some viruses spread so quickly, and why do they make us feel terrible? Answer these (and many more) questions through a simple yet impactful lessons. Pupils observe demonstrations that show the two methods viruses use to escape...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

In this activity, students investigate the life cycle of an engineered product and how the product impacts the environment. They analyze a product using a simple life cycle assessment that assigns fictional numerical values for different...

A brief explanation of life cycle is provided along with pictoral respresentations of three different examples of life cycles (apple tree, butterfly and frog). The term metamorphosis is introduced and the resouce has an interactive...

Students further their understanding of the salmon life cycle and the human structures and actions that aid in the migration of fish around hydroelectric dams by playing an animated PowerPoint game involving a fish that must climb a fish...

Explore the human body's need for a normal cycle of dark and light and apply this to an understanding of biological clocks in other animals. Test the effect of light on the development of mealworm larvae into adults.
