Scholars investigate an issue associated with food systems and design their own solutions. Working collaboratively, they follow each step in the design process to complete the 10th activity of the 13-part Our Hungry Planet series.

In 2018, the average fast food burger cost $2.64 while a salad averaged $4.14. Does the price difference matter to public health? Scholars consider that question and others in a brainstorming session about improving our global food...

How do people transport fresh water long distances to ensure everyone has access to it? The final lesson in the 10-part Fresh Solutions unit encourages individuals to design their own solution, or solutions, to that very problem. Groups...

Pupils explore the amount of water people use in agriculture and for personal use. They compare water usage for various crops to that of raising animals before considering solutions for increased access to safe drinking water worldwide....

The higher the number of letters in the final word for the National Spelling Bee, the higher the number of people killed by venomous spiders. Obviously, those two facts correlate, but no causation exists. Scholars view data based on...

Scholars use data to analyze and determine which sets of information need to be counted. They create a model to explain differences among chemical elements using graphs to prove concept mastery.

A puzzle isn't about the individual pieces, but how they work together. Scholars assemble a puzzle and discover missing pieces. They write a description of what they expect these pieces to look like, including as many details as...

How do scientists identify which elements originate from meteorites? Scholars learn about a sample of material found in a remote location, analyzing the sample to determine if it might be from Earth or not. They study elements, isotopes,...

When given too much data to simply memorize, it helps to sort it into manageable groups. The second lesson in the six-part series of Cosmic Chemistry challenges groups of pupils to take a large amount of data and figure out how to best...

Many upper level tests require pupils to interpret written descriptions of scientific principles. Scholars practice the skill by working through three levels of difficulty. Each question covers kinetic energy, gravitational potential...

Many pupils struggle to categorize and organize related content. Multiple quizzes on a variety of topics offer practice for these specific skills. Scholars move items around until they think each is placed in the proper position....

Evolution occurs though change over time, but can it go any faster? Scholars speed up the process of evolution and observe a simulation of 20 blue organisms fighting for survival. A graph displays the changes in phenotype over time. By...

Scientists discovered the first exoplanet in 1995 and by early 2018, they confirmed the existence of more than 3,700—that's a lot of data! As part of the PBS 9-12 Space series, scholars interpret data about exoplanets. They compare...

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...

Scholars use current satellite data to view solar events, solar features, and so much more. It allows them to make videos over time to observe patterns and visually understand the sun at a much higher level using the interactive that is...

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...

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...

Drugs interact with the brain to alter moods, emotions, and behaviors by changing the brain's chemistry, perceptions, and interactions. The final lesson in the Pharmacology unit shows scholars experiments, has them complete four labs,...

The third of a four-part series on Pharmacology teaches scholars how drugs enter and exit the body, how they act inside the body, how they affect the brain, and more. Over the course of the unit, groups complete two labs and one...

What exactly goes into the medications people take every day? Scholars learn about the chemistry of medications in the second of a four-part series on Pharmacology. Over the course of two weeks, class members complete seven experiments,...

Learn about the study of medications, including those found in nature and those made synthetically. The first of four lessons in a series on pharmacology includes lectures, hands-on experiments, research, and more.

How do police determine the speed of a car that has hit a stopped vehicle? Scholars determine the momentum of the car system both before and after a collision. They identify instances where the law of conservation of momentum appears to...

Why are gym walls padded and cars required to have air bags? Scholars observe two similar situations, such as those listed above, with only one variable altered. They identify the different variable and determine how the variation...

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...
