Angry Birds prepared them, but now pupils must prove their skills with projectiles! Scholars test different variables to determine which ones impact the distance the projectile flies. The experiment provides connections to kinetic and...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Based on the rate of melting observed from 2003-2007 in Greenland, it would take less than 10 minutes to fill the Dallas Cowboys' Stadium. The 17th lesson in a series of 21 has scholars use the ICESat data to understand the ice mass...

Pigs and humans have the same metabolism level and similar organs and systems, which is why they are often used in scientific laboratories. This worthy virtual dissection of a fetal pig divides into eight chapters: anatomical references,...

The solar energy industry in the United States added more jobs in 2015 than the oil and gas extraction and pipeline industries combined. With the field growing so rapidly, it's essential to understand what solar energy is and how it...

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars build...

The amount of energy Americans use doubles every 20 years. The first lesson in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in order...

More than 80 percent of the earth's surface originated from volcanoes. The 16th lesson in a 20-part series introduces the shape and development of volcanoes. It begins with a demonstration using a balloon and flour to illustrate the...

There has been an earthquake! Can you listen to the description of damage given by callers in order to determine the epicenter? The 11th of 20 lessons has pupils read a script of one emergency caller. The class records the information on...

What's cooking? A sizzling STEM unit challenges scholars to build a solar cooker that can successfully cook an egg. The unit opens with a study of Earth's rotation, the sun's energy, and shadows. Pupils use a compass and thermometer to...

What would the world be like with no insects? Ponder this question using a research-based STEM unit that encourages scholars to investigate insects from both a beneficial and hazardous perspective. They learn about insect behaviors,...

Almost every ancient culture observed the stars and saw pictures in the patterns. Studying stars allowed them to guide travelers, determine when to plant crops, when to harvest food, and the stories surrounding the images include some of...

Although the methods are all scientific, forensic science was started by police officers rather than scientists, who relied on observation and common sense. Young detectives use many tools to solve crimes around the school in a...

Have you ever wanted to shoot someone out of a canon? This simulation gives you that chance! In addition to a human, you can shoot a car, a piano, a cannon ball, and many other items. Scholars set the angle, initial speed, mass, air...

Why did Mr. Ohm marry Mrs. Ohm? He couldn't resistor. An electrifying simulation allows scholars to control both voltage and resistance in order to see the current change. The formula is displayed and as you increase one variable, it...

Orbit diagrams appear to be a work of mathematical art. The simulation helps scholars build their own systems of planets, stars, moons, etc., to observe their orbits. By altering their positions, velocities, and masses, a variety of...

Everything from pens to cars use springs — some are just on a larger scale! An interactive simulation encourages pupils to stretch and compress springs while observing the changes to force, displacement, and potential energy. Then they...

A multi-part lesson opens with a review of p waves and s waves. Then scholars use a simple s wave simulator to view the way the wave travels. Next, pupils use cups and various fluids to simulate p waves moving through different...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Currently, only 2.1% of global warming is felt on continents, while over 93% is felt in the oceans. The fourth lesson in the series of 21 on global warming is composed of three activities that build off one another. In the first...

Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...

Did you get to play with electric currents or were you grounded? An electrifying simulation shows how building up a charge of electricity creates a static shock once grounded. Pupils rub John's foot across the carpet and view the buildup...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over...
