Bring a historic chemistry experiment to life in your classroom! Introduce pupils to Thompson's ground-breaking discovery of the electron through a cathode ray simulation. The resource allows users to study the behavior of both electrons...

Do domed structures have advantages over their less-than-spherical counterparts? Junior architects explore the pros and cons of domes through a design challenge. Teams work together to plan, sketch, build, and test domes created from an...

Chemistry calculations can look a bit like alphabet soup at times. How do you help pupils make sense of it all? An interactive resource helps scholars sort through the symbols for common quantities such as moles, boiling point, and...

Combine a little solid and a little water and the solution is clear! An experimental lesson has individuals make calculations to create a sample solution of a given volume and molarity. They then create the solutions using a virtual lab...

Scholars practice calculating spring constants before performing hands-on experiments. They compare data for parallel and series springs. Finally, they learn how spring mechanics find applications in biotechnology, such as prosthetic limbs.

Do your young physicists get a little unbalanced when it comes to talking about torque? Scholars examine the effects of weight and distance on a balanced system with a simple interactive from the Rotation and Balance series. The resource...

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...

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...

Math and medicine go hand-in-hand. After viewing several infographics on historical adult obesity rates, pupils consider how they have changed over time. They then use percentages to create a new graph and write a list of questions the...

Long before modern labor unions, guilds worked to ensure that workers had a fair wage. But, in medieval Europe, they also cooperated with the government. Using a simulation and primary source analysis, young scholars become hatters in...

Compounding is dividing units. Pupils practice using compound measures such as units for speed and density to solve problems that range from straightforward speed problems to those requiring conversions. The last few items challenge...

More than 80,000 scholars earned college credit for Chemistry with the AP exam in 2015. The College Board released the free-response questions covering topics, including moles, that often confuse scholars. They also released example...

The College Board published the mean score on the 2016 AP Chemistry exam as a 2.69, but a minimum of a three is required to earn college credit. Help pupils study for the upcoming exam with actual test questions, sample answers, and...

Two different groups of scientists published scientific papers in 1980 offering proof of a large asteroid hitting Earth between the Cretaceous and Tertiary layers of ground. Scholars use a worksheet to analyze the same type of data as...

Learners consider production possibilities using an authentic test question from College Board. Other questions include practicing supply and demand curves and examining the effects of inflation, employment, and other variables on a...

What happens if Mexico decreases tariffs on imported cars? Learners consider the question and others using authentic College Board materials. Other questions include evaluating the effects of government spending on a fictional country...

A country experiences inflation. What options does the government have to control the problem? Using authentic materials from College Board, learners consider the problem. Additional questions explore supply and demand curves, as well as...

How could consumer confidence affect an economy otherwise operating smoothly? A prompt from College Board examines the topic. Other questions include exploring the production possibilities of two fictional nations and evaluating a...

A fictional country is facing tough economic times and has a few options to tinker with the economy. Which is the best path forward? Scholars consider the best way to reverse a recession using materials from College Board. Other queries...

All goods have a social cost. A set of questions considers how to best calculate the impact the production of goods has on society. Other practice problems from College Board consider supply-and-demand curves and the impact of licensing...

Bag the sweet resource for later use! Pupils learn about engineering design by developing a new, improved bag for candy from thin plastic sheets or from paper. The bags are to be visually appealing, but should also be functional. To...

World War II was not just waged in Europe and Asia; the home front was key to Allied victory. Using newspaper clippings from World War II and a map, scholars plot out wartime production in the United States. After that, class members...
