As a Matter of Fact
Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

Where Are We Going?
Come take a ride on the space bus! Scholars go on an imaginary trip to pick up their peers from the inner and outer planets while reinforcing math skills. First, learners round decimals to identify each planets' distance from Earth....

Carbon Dioxide Exercise
Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five...

Powers of 10
Young scholars explore universe, and examine how big it really is and how scientists measure the distances or sizes of things by estimating sizes of different objects and reading and writing numbers in scientific notations.
