Can you infer the wiring diagram of a series of lights based on their behavior alone? Scholars work with multiple boxes of four lights. They must flip the switch and decide how the lights are wired. By applying their knowledge of...

Scholars must understand freefall before they learn how objects like airplanes fly. They apply knowledge of velocity and acceleration to predict speed and direction as part of a larger series on vectors and projectiles.

Scholars apply their understanding of circuits and electric pathways to many simulations. They move through three different activities and 18 questions, receiving immediate feedback after each answer. The lesson is part of a larger...

Resistance is not futile ... it is voltage divided by current. Scholars apply their knowledge to a series of ranking puzzles. First, they consider wires of varying lengths and then wires of varying cross-sectional areas. Finally, they...

Never underestimate potential—electric or your own. Scholars apply a color scheme based on the changes in electric potential as part of a series on electric circuits. They consider splitting wires, light bulb placement, and voltage as...

Join the resistance—Ohm! Scholars apply Ohm's Law to problems of increasing difficulty as part of a series on electric circuits. The lesson begins with simply doubling and tripling voltage or resistance. It ends with having pupils solve...

Better than some television series, parallel series circuits provide practice for calculations. Scholars work through a series of problems, each progressively more difficult. They apply knowledge of voltage calculations, resistors, and...

Pupils apply their knowledge of the shape and slope of graphs to interpret the motion of an object.  Three levels of difficulty provide plenty of practice with support thanks to the "Help Me!" button offered with each question.

Increasingly, colleges and employers want applicants with strong conceptual analysis skills, so give them some practice! Applying these skills to position-time graphs encourages synthesis of knowledge. To complete an installment of a...

Matchy-matchy no longer exclusively applies to fashion. Scholars work through three levels of practice matching position and velocity graphs. Part of a series covering dimensional kinematics, each question provides immediate feedback and...

Pupils apply their understanding of motion to 11 practice problems as part of a series on dimensional kinematics. They view a dot diagram animation and read descriptions to identify which match. As a bonus, the interactive offers...

Most pupils learn quickly how to apply Newton's Second Law equation to calculate net force. However, many struggle to determine net force before calculating the value of an unknown force from a force diagram. As part of a larger series...

Scholars quantitatively apply their knowledge relating impulse, force, and time in the collision of objects. Three progressive levels challenge pupils with different ways of analyzing these problems. They identify multiple collision...

The acceleration rate of a flea jumping works out to 50 times faster than the acceleration rate of the space shuttle. Pupils apply knowledge of acceleration to dot diagrams, velocity-time tables, and word problems. They solve for...

The majority of all confirmed exoplanets relied on Kepler's laws to discover their locations. Scholars learn how to apply Kepler's laws and then practice using data to discover exoplanets. They benefit from NASA video footage, NOVA...

The Kepler missions discovered and confirmed more than 2,650 exoplanets to date. A video shares the data from the first five discoveries. It provides graphs and diagrams to put each discovery in perspective to help scholars discuss the...

Take a load off! Introduce junior engineers to the effects of load on structural design with an easy-to-use interactive. Individuals apply one of many load options, examine its effects, then learn about the safeguards employed during...

Scientists detected exoplanets by measuring how the brightness of stars changed over time. Young astronomers interpret and analyze the same data that led to exoplanet discoveries. They learn to apply light curve graphs and connect the...

Create a company, advertise it, and hope it grows. The seventh of eight parts in the Google CS First Friends unit challenges future business leaders to apply computer coding to create an advertisement for a company. After pairs come...

Climate systems involve sunlight, ocean, atmosphere, ice, land forms, and many other factors. Scholars explore each of these variables related to the Pacific Northwest rain forest. They use an online interactive to investigate the polar...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

Learn to analyze vector addition on graph paper through multiple levels of practice problems. Pupils begin with two component addition and move through three and four components to prove mastery as one part of a series on vectors and...

Around 500,000 children under the age of six suffer from elevated levels of lead in their blood in the United States. Scholars apply their knowledge about lead to a fun game. As they correctly answer questions, they move their pieces...

Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...
