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

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners investigate why apples turn brown. Learners discover that lemon juice interferes with the reaction that causes the browning.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

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.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

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 quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this art meets chemistry activity, early learners discover the almost magical absorbent properties of salt while creating ethereal watercolor paintings.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.
