In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

In this nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food labels

In this investigation, learners gather information on various food items during a field trip to a local grocery store.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

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

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can

In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.

In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

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 use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

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

This is a classic exercise for visualizing the scale of the Solar System.

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

In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i
