This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.

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

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

This activity (page 2 of the PDF under SciGirls Activity: Bogs) is a full inquiry investigation into decomposition.

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

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 activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!

In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

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.

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