In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

In this story time program, young learners listen to the Dr.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.

In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

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.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

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

This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

Learners investigate how the temperature of water affects its density.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.
