In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta

In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.

In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

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.

In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.
