With global temperatures on the rise faster than ever recorded, the effects of a heating planet could be devastating. Allow learners to discover just what the world is in store for if the warming continues through a series of videos, a...

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

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.

How do greenhouse gases affect the climate on Earth?  Pupils explore the concept by first building their own apparatuses to model the greenhouse effect. Then, they record data to measure temperature change and determine...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Ocean currents have a profound effect on the climates of the continents, especially those regions bordering on the ocean. The Gulf Stream makes northwest Europe much more temperate than any other region at the same latitude, and the...
