How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Dramatize the stars and planets as they become a visual representation of the solar system in this activity. Young astronomers track and simulate various constellations as they orbit the Earth to learn the position and motion of...

Did the image I drew match the image you saw? By simulating a satellite and a ground station, teams of two transmit data in the form of pixels in order to recreate an image. They use four different levels of brightness, creating slightly...

Plop, plop, fizz, fizz, oh that one is the fastest. The teacher demonstration is the second part of a four-part series. The class observes how different pill types dissolve in simulated stomach acid. They determine which one dissolves...

Intrigue the class by completing a lesson on meiosis, filled with challenging and insightful activities to spark the interest of every person in the room. Each member of the class learns about genetic disorders due to faulty meiosis, and...

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.

Life's not fair, but decisions can be. The 17th installment of a 21-part module teaches learners about fair decisions. They use simulations to develop strategies to make fair decisions.

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

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...

Apply the principles of geology to a series of collaborative, hands-on class activities. Young earth scientists learn more about igneous, metamorphic, and sedentary rocks before classifying and weathering rocks that they find....

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...

Take a spin to determine experimental probability. Small groups spin a spinner and keep track of the sums of the spins and calculate the resulting probabilities. Pupils use simulated frequencies to practice finding other probabilities to...

Flip a coin to determine whether the probability of heads is one-half. Pupils use simulated data to find the experimental probability of flipping a coin. Participants compare the long run relative frequency with the known theoretical...

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...
