Laws of motion apply both in space and on Earth. Young experimenters model object impact on the Earth and moon. They use data to determine the effect mass and velocity have on the resulting craters and how that relates to the energy of...

It's sure getting hot out there! Scholars analyze satellite data on land use and surface temperatures, and then learn how to ground truth satellite data through an activity. They apply technology to identify urban heat islands and...

Kids act as scientists and preditors in this short natural selection activity; they collect and analyze data, then apply their new knowledge to real-world examples of natural selection. The layout of the worksheet is easy enough to use...

Can you identify mutations just by viewing DNA sequences? Scholars apply prior knowledge of DNA sequences to do just that in an engaging activity. They transcribe and translate genes, thus identifying the locations of mutations. Then,...

In this temperature scales activity, students are given the equations to convert from Fahrenheit to Celsius and from Celsius to Fahrenheit. They apply to equations and convert given temperatures.

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

Fifteen questions about our solar system make up this interactive review game. It was written by a teacher in the UK, and therefore the monetary winnings for answering correctly are in pounds. The content applies, however, to any...
