In this health activity (located on page 4 of the PDF), learners will discover the importance of hand washing by observing mold growing on potatoes.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

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

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

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

In this health activity (on page 3 of the PDF), learners will learn about the body‘s defenses against invasion from tiny particles.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this activity, learners explore the work of paleontologists.

In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

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

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

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

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 activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.
