To show the magnitude and direction of all forces acting upon an object, scientists use a free body diagram. This simulation serves as an introduction to free body diagrams allowing scholars to build their own. Pupils select the proper...

Provide the details about Felix Baumgartner's sky jump from the far reaches of our atmosphere, 39,045 meters up! Then get your physics free fallers to evaluate the factors that played a role in his acceleration, the time to reach maximum...

Pupils read a description of a physical situation and select the free-body diagram that best matches. As part of a series on applying Newton's Laws of Motion, scholars reinforce their skills applying forces and considering their relative...

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.

Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

The average student scores less than three points, out of five, on the AP Environmental Science test. Most do well on the multiple choice and struggle with the free-response section. Encourage extra free-response practice with actual...

It's rare for even 40 percent of test takers to pass the AP Physics 1 exam. Improve those odds for young scientists with the help of actual free response questions covering topics from free body diagrams to velocity. The College Board...

AP® free-response questions are often challenging for scholars. Give them practice writing free-response questions using former questions from the AP® Biology exam on topics such as genetic mutations, cellular respiration, evolution, and...

Less than half of AP Environmental Science test takers pass each year. The College Board releases previous test questions covering topics from greenhouse gases to ecological succession to help scholars prepare for future assessments. Use...

Almost half of test takers passed the AP Environmental Science exam in 2017. Use the free-response questions on the topics of pollution and ecosystems to improve writing skills in preparation for the AP exam. Discuss the scoring...

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...

More than half of AP Chemistry test takers earn a high enough score to get college credit. Improve that statistic by using past test questions including precipitate, molarity, and chemical equations to prepare for a future exam. The...

With AP Biology remaining the most popular AP science exam, many teachers need help preparing. The College Board offers the actual free-response questions from the 2017 test covering pollination, germination, and more. Scholars learn the...

A remarkably high number of scholars passed the AP Biology exam in 2016 with over 61 percent earning college credit. The College Board released the entire free-response section for future scholars to study. After answering the eight...

As one of the few AP tests that count for second year college course credit, the AP Physics 2 exam requires a higher level of knowledge than most. Help young scientists study for their upcoming AP Physics 2 exams with previous...

In 2017, more than 15,000 scholars earned college credit based on their AP Physics 2 exam covering lenses, energy, and more. The College Board released the free-response questions, sample answers, and scoring guidelines from that exact...

While the AP Physics 2 test maintains the reputation for one of the most difficult AP exams, scholars feel better prepared after practicing free-response questions on currents, conservation of energy, and displacement. The College Board...

Do you know how to help scholars study for the AP Physics test? Use the free response questions from the 2017 exam covering topics from circuits to waves to prepare pupils for future AP assessments. After answering the questions, read...

Generally, scholars struggle on the free response portion of the AP Physics 1 exam more than the multiple-choice section. Scholars benefit from additional practice with the help of previous test questions, including questions on forces,...

Whether determining orbitals of space craft or designing experiments with conductive dough, many young scientists discover physics is phun and attempt the AP exam to get college credit. Use the free response questions from the 2018...

Mother Nature may have less control of temperature than you think! Young scholars consider the effect urban environments have on local and surrounding temperatures as they respond to one of four free-response assessment questions from...

There is a strong correlation between the carbon dioxide concentration in the air temperature. Scholars offer explanations for the correlation in one of four AP® free-response assessment questions. Their analyses in the other questions...

Can the increase in meat production keep pace with the increase in population? Individuals analyze data to determine when human populations will exceed meat production at the current rates of increase. They also consider infectious...

The average AP Biology score dropped in 2018 with the addition of more data tables and graphs. Offer additional practice free-response questions by using the questions from the 2018 AP exam covering phylogenetic trees, cell structure and...
