This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

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

Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.

In this activity, learners examine the culture and history of the tomb site.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

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

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Learners investigate how the temperature of water affects its density.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

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

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 make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.
