Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

Geology scholars test their rock identification skills in an interactive that examines the rock cycle from the three main nodes of rocks. Other topics include visual clues to rock identity and the conditions needed to make rocks change...

Get earth science students excited about the formation of rocks with an engaging interactive resource. Learners analyze the composition of granite, then study the various processes that work together to make igneous, sedimentary, and...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

An interactive lesson places pupils as scientists who must learn why the ozone layer is being destroyed by analyzing the data from multiple satellites. The first analysis shows how UV is related to the ozone cycle. The second...

How did scientists measure the speed of incredibly fast things before the invention of high-speed photography? Scholars virtually perform ballistics tests to discover the process. They control the rifle type, bullet mass, and target...

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

All human infants are lactose tolerant, yet some adults are lactose intolerant—why is that? Individuals discover the process of gene mutation through a study of the lactase gene (LCT). They understand the geographic connections,...
