Learners see that a carrot slice sinks in fresh water and floats in saltwater.

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.

In the kitchen, learners can perform their own density investigation.

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.

Learners act as engineers and design mini submarines that move in the water like real submarines.

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 examine the culture and history of the tomb site.

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

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.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.
