In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this paleontology activity, learners explore the system behind dinosaur nomenclature.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this activity, learners will turn healthy greens into crispy snacks. Explore concepts of nutrition, dehydration and cooking to create healthy food.

In this activity (p.7-8 of PDF), learners examine fossil formation.

In this activity, learners discover how a piece of fruit can act as an electrolyte, conducting electricity between two different metals.

In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

In this activity, learners will put together towers using building bricks, then take the tower apart and challenge themselves to use the same bricks used to build a bridge.

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 look at and touch marine animal skulls to compare them and think about what they eat.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this "Sid the Science Kid" activity from Episode 106: My Mushy Banana, learners explore the effects of decay by comparing and contrasting something (an old pumpkin) that's decayed with the same thi

In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.
