An eight-unit electronic textbook provides a guide to AP® Biology. Each of the 28 chapters include an introduction, multiple lessons, a summary, review questions, and test prep questions. Teachers see how each lesson connects to a big...

The Environmental Protection Agency monitors sensors to track air pollution and set clean air standards. Enthusiastic young scientists use similar sensors to gather data in their area and then apply the gas laws and conservation of...

An engaging unit on wildfires includes three sections, including a background section with eight lessons and five activities, a field experience section with 13 lessons and five activities, and a conclusion section featuring an analysis...

We all know photosynthesis happens, but why should we care? Here is a unit that covers everything young scholars need to know about photosynthesis. Hands-on activities, assessments, and lectures guide pupils though the physiology of a...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Life science teams experiment by placing sprigs of Elodea into a sodium bicarbonate solution and counting the oxygen bubbles produced. Data is recorded and graphed on a Google spreadsheet, making this not just a lesson in photosynthesis,...

A well-written lesson plan, second in a series of four, gets high schoolers exploring how the Antarctic food web is impacted by climate change and the associated melting of polar ice sheets. It begins with a PowerPoint presentation about...

Looking for a tree-rific addition to your water cycle unit? Teams of young foresters examine the role of transpiration in the water cycle through a week's worth of activities. Pupils analyze how trees take in and transport water during...

Discover what links photosynthesis and food chains together. Scientists explore the basics of photosynthesis, including its products, during an animated activity. While watching the video, investigators also learn the importance of sugar...

Find out why Earth hangs in a delicate balance between cellular respiration and photosynthesis with a compact activity. Biologists compare and contrast cellular respiration with photosynthesis by examining the functions and products of...

Carbon dioxide is on the rise; does that also mean a rise in danger to humans and animals? Scholars learn what that means for the environment and more specifically the ocean. They examine data on the pH of different ocean areas and learn...

Chemistry is the foundation of good farming. Learners explore how chemical bonding applies to agriculture. The lesson highlights the difference between organic and inorganic compounds and how similar compounds bond in very different ways.

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules and...

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...

How do oceans affect weather patterns? Learners define vocabulary associated with dew point, topographical lifting, condensation, and formation of clouds and precipitation as they explore the weather in the Pacific Northwest. They also...

How diverse are living things? Individuals explore topics such as cells as the foundation for life, cell division and genetics, molecular biology, and animal reproduction using an open resource Biology textbook. They learn key terms...

One important skill in analyzing scientific evidence is identifying facts versus opinions. Scholars identify pieces of evidence from the film The Day the Mesozoic Died and then discuss this evidence in small groups at the end of each act...

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

As the world population increases, demands on the carbon cycle also increase. A well-designed lesson first explores the greenhouse effect and its impact on global warming. Further sections have pupils study the effect of greenhouse gases...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....
