In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.

In this activity, learners will conduct an experiment to discover methods of reventing foot mold growth on food.

Although we may not admit it, all humans fart or pass some gas. In this activity, learners make their own model to mimic food passing through intestines and discover what releases gas.

In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners are divided into teams.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

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

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

In this activity, learners use sets of cards to assign microorganisms to different groups.

Learners make kimchee or sauerkraut, which is really just fermented cabbage, in a 2-liter plastic bottle.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.

In this activity (on pages 2-8), learners experience how scientists use classification in their study of animals.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.
