Learn to find the slope through a single point. The interactive provides a visualization of how to find the slope of a tangent line. With the aid of the visualization, pupils see the definition of the derivative in action. Class members...

How can you determine the rate of change on a curve? Pupils use the interactive to discover what happens with the average rate of change as the point move closer to the other. Using the definition of the derivative, learners find that it...

Does the value exist? The interactive allows pupils to visualize the Intermediate Value Theorem. Using the visualization, individuals respond to questions using specific values and general values. The class comes to the conclusion what...

Does your blood type matter? The video explains the four main blood types and the importance of knowing blood types when performing transfusions. The interactive reviews the information with a quick graphic organizer and questions.

Do predators look for different things in different seasons? The quick interactive shows how some species survive longer in one season than another based on the conditions. The challenge questions encourage pupils to demonstrate that...

Can natural disasters alter natural selection? The interactive explores this concept with mice living through a forest fire. As the environment changes, the camouflage also changes. How does this one disaster impact future generations?

Some molecules move through a membrane with diffusion while others require protein channels. The video and interactive discuss both types of passive transport. Challenge questions allow scholars to demonstrate their understanding.

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.

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...

If your pupils think relative velocity is the velocity at which you can run away from your relatives, they need this simulation. Two bikers want to meet at a specific time. Scholars alter the velocity of one rider to arrange the...

How do we know how long ago a dinosaur lived or an ancient fire pit was used? Scholars learn about the application of carbon dating and half lives to discover things about the past. They adjust the amount of radioactive carbon in the...

Everything is made up of atoms, but what are atoms made up of? The simulation explores subatomic particles. It focuses on hadron, boson, and lepton groupings as scholars learn about quarks, neutrinos, gluons, and more.
