Hot Air Balloon
It is more than just blowing hot air. Pupils first build a hot air balloon out of tissue paper by cutting enough panels of tissue paper to form a balloon shape and glue the panels together. Using a hot air gun, individuals then inflate...

Journey to the Bottom of the Sea
Follow the path to the sea floor. Pupils play an online interactive board game to reach the bottom of the sea. Participants must match descriptions of creatures to a property of water dealing with oxygen, food, light, or density to move...

Buoyancy in Water
Change where an object floats in water. Pupils experiment with a Cartesian diver by squeezing on the side of a plastic bottle. Learners pay attention to the bulb of the pipette as the bottle is squeezed to determine what is happening...
University of Waikato
Density
Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

Temperature, Salinity and Water Density
The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

Rainbow Water Stacking – Density and Salinity
Create layers of water. Pupils investigate different densities of colored water caused by salinity by trying to stack layers of water. Scholars compare two water samples to determine which is the most dense. As the class members work...

Model of Prosthetic Leg
Give the class a leg up in their understanding of engineering. A STEM activity has learners design a prosthetic leg that can kick a ball. They build a prototype of the prosthetic, keeping track of the design costs associated with their...

Foil Boats
How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...
Corbett Maths
Density
A short video introduces the triangle that illustrates how to find any value given the other two in the density formula. Class members use the triangle to work several problems to find the mass, volume, or density of an object.
