In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners will build a design and build a place for pollinators to drink from.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

In this nutrition activity (page 3 of the PDF), learners will record their food consumption for one day, and then evaluate how their actual diet matched up with the recommended diet.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners discover the three R's of environmental protection: reduce, reuse, and recycle.

After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).
