In this activity, learners will explore density and it's relationship with mass.

In this activity, learners will explore how and why weight distribution works.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

Learners will collect pennies to donate and will combine charitable giving with estimating and calculating with money. To start choose a charity or something to save up for together.

In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.

In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners will explore the physics of air by making a snake kite.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

In this activity, learners with explore the gases present in air. They will then build their own wind cannons and challenge family and friends to a friendly competition.

In this math lesson, learners use inchworm measuring tools to measure the lengths of several objects in the room.

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

Learners make a counting/estimating jar to exchange with friends or bring home.

In this activity, learners will create their own coral polyps - the basis for a coral reef.

In this activity, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.

In this quick activity, learners explore static electricity using a plastic comb, wool cloth, puffed rice, and a plastic bag.
