In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

In this activity (page 19 of the PDF) learners will create a soda bottle bioreactor by exploring the science of composting, comparing variables such as reactor design, moisture content, and nutrient r

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, learners conduct tests for proteins, glucose, and starch.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

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

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity (on pages 23-29), partners use the Plant Traveler Cards, along with a world map and map worksheets, to follow plants such as cassava, chocolate and coffee that grew first in one part

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

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 kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this activity, learners will discover why there are holes in bread.

In this activity, learners investigate the history and development of agricultural biotechnology.
