New ReviewIf only there was a graph to show the distance traveled over a period of time. Given distance-time graphs, pupils read them to determine the answers to questions. Using the distance and time on a straight line, scholars calculate the...

New ReviewA video that demonstrates the process for cooling atoms launches a journey to comprehend physics. After watching the video, class members answer multiple-choice and short-answer questions to prepare for a whole-class discussion of the...

New ReviewDiversity in a biome leads to some unique characteristics vital to the natural environment. Young scholars use an interactive map to explore the vegetation and climate of the Gorongosa National Park. They collect climate data to compare...

New ReviewHumans tend to huddle together when cold and move around more when warm, but do gas particles follow the same pattern? Scholars use a temperature probe, a pressure sensor, and air to study the relationship between temperature and gas...

New ReviewWe know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

New ReviewLet 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...

New ReviewAre brighter stars actually brighter? Turns out they are probably just closer! A presentation compares features of stars to our favorite star, the sun. In addition, solar lovers learn to classify stars based on their masses,...

New ReviewScientists discovered the first law of thermodynamics 25 years after the second law of thermodynamics. The seemingly obvious discoveries sometimes confuse scientists while more complex challenges encourage extra study—and take more time...

Winter, spring, summer, and fall—Earth experiences them all! But what about Mars? Scholars compare the planets in terms of distance, tilt, and rotation during a lesson from PBS's Space series. Great visual models of Earth and Mars, plus...

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...

Is Earth's energy flow a little off balance? Explore our energy budget using a click-through interactive. Scholars discover the many factors that move solar energy around the planet and why the system is no longer in equilibrium.

Winter, spring, summer, fall, and hurricanes? With the help of a video that is part of a larger Seasonal Science series, learn why hurricanes have a season all their own. Viewers integrate knowledge of the causes of hurricanes, factors...

When temperatures get extreme, physics gets a little weird! Show physics scholars the lowest man-made temperature to date, as well as the extreme heat of the Big Bang using a video from an extensive playlist. The narrator explains some...

Airline mechanics must be precise, or the consequences could be deadly. Their target ranges alter with changes in temperature and pressure. When preparing an airplane for flight, you must read a maintenance graph. The second lesson plan...

If objects have no heat, how do they can gain and lose it? Scholars experiment with heat, temperature, and specific heat of various substances. They create definitions for these terms based on their own conclusions to complete the fourth...

What can the electromagnetic spectrum tell us about the sun? As it turns out, quite a bit! See the sun in a whole new light with a video from NOVA's Sun Lab unit. The narrator describes the electromagnetic spectrum in terms of visible...

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

You walk into a room and immediately notice it is cold, but how did your body recognize it? Scholars explore how their skin determines if something is hot, cold, or just right. They learn about receptors and response times through...

Why do we sweat? Scholars analyze data about body temperature, sweating, and other factors to better understand sweating. They note the changes after drinking ice water to sweating, skin temperature, and body temperature. Analysis...
