In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

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.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

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

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 discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

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

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

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.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

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.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

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.
