New ReviewSome say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

New ReviewGet lost at sea amid colorful ocean currents! Learners discover the patterns of movement and temperature in the North Atlantic's currents through a simulation, part of PBS's Weather and Climate series. The resource contains background...

New ReviewIs 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.

New ReviewWinter, 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...

New ReviewWhen 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 of...

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...

Which holds more influence, the environment over humans or humans over the environment? Young scientists explore an online interactive that addresses this discussion. They observe changes in the natural world over time and see which...

Can your scholars solve the mystery of why salts dissolve? A virtual workbench allows them to experiment with temperature and solubility with no solution prep and no post-lab clean up! Users determine the solubility of a variety of...

So, you've headed out into the wilderness and forgotten your camp stove? What's a chemist to do? Solutions may be the solution! Scholars use a virtual lab workbench to create solutions that would be capable of heating food, courtesy of a...

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Mars, Earth, and Venus contain atmospheres that generate weather. Young scientists explore the temperature of inner planets. They create a model simulating the greenhouse effect before researching and answering guided questions to...

Things are really getting heated in the lab! Science scholars scope out the facts about heat energy transfer using a simple lab from the K20 series. Groups collaborate to observe temperature changes between hot metal and water, then use...

How can something as vast as the universe also be flat? Go beyond the Big Bang Theory using a video from an expansive physics playlist. Topics include the expansion and inflation of the universe, why opposite sides of the universe are...

Explore particle motion between solute and solvents. An interactive simulation allows learners to observe the motion of solute particles as they interact with the solvent particles. It provides an option for including Brownian dynamics...

It's all uphill from here! Scholars examine the pattern of random particle motion up a staircase. The simulation shows how the linear increase in energy corresponds to an exponential decrease in particle concentration.

Understanding viscosity is key to keeping your engine running smoothly. An experimental lesson measures the viscosity of different motor oils. Learners compare their results at different temperatures.

Keep your lessons on the lighter side! A chemistry lesson has learners collect butane gas to calculate its molecular mass. They measure the mass of the gas using a displacement method.

As part of a larger series, an informative video introduces the concept of perpetual motion machines and the science proving they don't work. The narrator then shares machines that appear to work and highlights the hidden sources of energy.
