How close are we to a cure for diabetes? It seems the cure which has a connection to stem cell research is a possibility! Learners explore the concept of stem cells with an engaging hands-on activity. A PowerPoint presentation provides...

It is all in a matter of time. The model curriculum module uses parametric equations and vectors to solve problems dealing with particle motion along a curve. At the beginning of the lesson, the unit reviews parametric equations and...

An environmental factor, such as a drought, sometimes speeds up the rate of natural selection. Scholars analyze data on the beaks of birds around the time of the drought. They compare those that survived to those that perished and find...

A mass extinction event caused by an impact usually leaves a crater. Scholars use data from 10 different sites around the world trying to determine where to look for the crater. They use data, listing the amount of various minerals to...

Gene switches work similarly to light switches in controlling one feature of their environments. Scholars study the Pitx1 gene in a specific type of fish. They learn the different ways this switch controls various body parts and...

Two fish appear different, but how do scientists determine their genotypes? Scholars practice performing test crosses to determine the genotypes of fish given their phenotypes. They answer in-depth comprehension questions and complete...

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...

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...

2018 saw some of the highest AP Chemistry scores in years. The College Board released each test question covering topics from enthalpy to net ionic equations, as well as scoring guidelines and more to benefit future scientists. Example...

More than 83,000 scholars earned college credit, thus saving time and money by passing the AP Chemistry exam in 2017. Use the exact test questions covering concepts from activation energy to solubility to prepare for the upcoming...

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...

While AP Physics 1 counts as an introductory college Physics course, AP Physics 2 counts as a second-year college Physics course. Help scholars prepare for this more advanced college-level test with questions from previous assessments...

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...

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...

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...

How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

What did Earth look like 4.5 billion years ago, and what was the climate like then? Scholars explore a view of Earth throughout history. They observe continents moving, temperatures fluctuating, and huge changes in ecosystems. A activity...

The spot you are standing in right now—how did it look 2,000 years ago, one million years ago, or even four billion years ago? Scholars use a model of Earth throughout history to learn about continental drift, climate change, changes in...

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...
