Sugar isn't good for you, but it's great for microbes. A simple experiment has pupils investigate the digestion of starch by microbes to produce sugars. They apply two bacterial cultures, an amylase solution, and distilled water on a...

HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...

We all drink milk as babies, so why can't we all drink it as adults? Examine the trend in lactase production on the world-wide scale as science scholars analyze and interpret data. Groups create pie charts from the data, place them on a...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...

Substances that decompose with the help of living organisms do so at different rates. Scholars experiment with Winogradsky columns to determine the rate of decomposition, the oxygen and sulfide content changes, and bacteria levels. The...

Who actually goes looking for a virus? Expose your class to the high-stakes life of an epidemiologist on the trail of the Nipah virus. Pupils engage in a short video, then examine how scientists predict, model, and find the source of...

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...

Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...

How well do you know the relationship between enzymes and activation energy? This resource provides you with short quizzes and tutorials to provide feedback for those topics you don't understand.

[Free Registration/Login may be required to access all resource tools.] This activity describes how enzymes speed up biochemical reactions and their importance to living organisms.

A hands-on activity from Access Excellence for advanced biology classes. Students are given a crime scenario and three suspects. Their mission is to determine 'Who Dunnit?' by obtaining and analyzing DNA samples. Requires extensive...

Experiment with factors that affect the activity of the weed killer Roundup. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and...
