Ever wonder how the Internet works? The lesson teaches scholars the basics of graph theory and how it applies to the Internet. They perform simulations to see how information is sent on the Internet.

Mathematics can model just about anything—so why not simulate the height of water in a toilet bowl? The lesson asks pupils to create a graphical model to describe the relationship of the height of the water as it empties and fills again....

Many people know cats mark their territories by rubbing the back of their necks to leave a scent, but not many people know beavers also leave a scent to mark their territories. During the first activity of two, scholars use their noses...

The United States Immigration Policy is incredibly complex. To gain a deeper understanding of the criteria, quotas, preferences, and categories of immigrants admitted to the US, class members engage in a role playing activity that...

What can math say about natural phenomena? The fifth STEM lesson in this project-based learning series asks collaborative groups to choose a phenomenon of interest and design an experiment to simulate the phenomenon. After collecting...

Look at climate change around the world using graphical representations and a hands-on learning simulation specified to particular cities around the world. Using an interactive website, young scientists follow the provided...

Does light affect molecules or does it go right through them? The simulation explores four different types of light: microwave, infrared, visible, and ultraviolet. Scholars alter the energy level of each as it is aimed at seven different...

The universe is full of sources of energy. Explore the energy of pulsars with your classes through a simulation. An interactive lesson allows learners to manipulate the angle of rotation of both the earth and the pulsars. A real-time...

Why does it take Pluto 90,000 days to orbit the sun, but it only takes Mercury 88 days? An interactive lesson helps pupils find a connection between the speed of orbit and distance a planet is from the sun. The simulation allows for...

Planetary atmospheres vary greatly from planet to planet. Explore these variations by experiencing the motion of the atmospheric molecules through an engaging simulation. Pupils discover that temperature and mass contribute to...

How are scientists able to measure distances between stellar bodies? Turns out it's not very easy! Learners explore the process of trigonometric parallax as the method of determining these distances. They experience the same challenges...

Noting the color of a star is equivalent to taking its temperature! A creative lesson describes the connection between a star's temperature and the color it emits. As pupils interact with a simulation, they learn how to connect the...

Elements don't have fingers, but they have fingerprints! An interactive simulation gives young scientists the opportunity to study orbital changes of an atom and the corresponding spectrum reading. They realize how each atom has a...

Explore the birth and possible death of the universe. An interactive simulation allows learners to manipulate the Hubble Constant to model the expansion of the universe from birth. Varying the constant provides different scenarios for...

As a star ages its composition, size, and temperature change. Using an interactive simulation, learners explore these changes over the lifetime of a star. They see the change in temperature and luminosity graphically and a visual...

Determine the change in elevation on a mountain road. Individuals use the interactive to simulate a truck driving up a mountain road with a 30-degree incline. They determine missing sides of a 30-60 right triangle to find horizontal and...

Get the most out of a pizza. Class members use an interactive to simulate cutting a pizza to determine the maximum number of slices possible. The pupils create a set of data points and determine the equation that models the relationship.

Make a volcano erupt in your own classroom! Young scientists use household and craft materials to model and simulate the eruption of a volcano.

Build a soccer field through a little mathematical analysis. Individuals manipulate the dimensions of a soccer field as they drag points to new positions. The simulation shows the corresponding intercepts and area. As pupils explore the...

Be a hero, not a zero! Help your classes understand how to solve quadratic equations with the zero product property using an animated simulation. Using the controls, scholars manipulate the zeros and watch as the function and its factors...

Do curves slow runners down or help their speed? Pupils simulate a 200-meter dash to calculate the angular and linear velocity of a runner. They then determine whether the runner is faster around the curved section of the track...

Discover firsthand the effects of internal waves on coral reefs. Through a series of experiments, learners simulate internal waves and upwelling events as they make observations on the movement of water and other debris. They then...

And the winner is ... not always who it appears to be. An interactive gives the directions for a dice game that on the surface gives one player an advantage over the other. Pupils look closer at the possible outcomes and find the...

Learning about slopes from a hike in the woods is a walk in the park. Scholars slide a cutout of a person to simulate a hike along several paths. Passing through indicated points reveals the type of slope (positive, negative, zero, or...
