In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

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

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

In this activity, learners explore density and buoyancy as they design and construct rafts.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.
