This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.

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

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

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

In this activity, learners will review the functions of basic digestive organs, understand how diet affects digestion, understand how digestive tracks may differ, and then step outside to compare the

Learners use a simple process to extract DNA from strawberries.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

In this activity (p.7-8 of PDF), learners examine fossil formation.

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

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

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

In this activity (on pages 26-33), learners play parasitologists, solving several "mysteries" about people who got sick from various parasites. In teams of four, each member solves one mystery.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

In this online simulation, learners use antibiotics to cure patients with bacterial infections.

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

In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.
