This activity is a sensory experience that recreates the sounds of a pond at night.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.

In this activity, learners will investigate the sounds of the heart.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity about flight, learners explore how high they can jump. Learners dip their finger in ink or dirt, then jump as high as they can and mark paper attached to the wall.

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.

In this activity, learners build water-propelled engines from soft drink cans.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.
