In this outdoor activity, learners release a portion of a lawn from human control—no mowing, no watering, no weeding, no pest control—and then investigate the changes that result over several weeks.

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

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity (on pages 9-14), learners dissect a real flower -- the kind of work botanists do.

This activity is designed to introduce learners to genes, genotypes and simple inheritance patterns.

In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this graphing activity (on pages 33-40), learners investigate how much and what kinds of food sea otter pups eat during their first year of life.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Water treatment on a large scale enables the supply of clean drinking water to communities.

Learners will determine their respiratory rate and explore the factors that affect breathing rate by filling out and using the Respiratory Chart provided in the lesson.

In this activity (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own reflection.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this activity, learners survey living organisms near where they live or go to school, and create a local field guide.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this outdoor fall activity, learners find out what living in or under a layer of leaves is like.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.
