Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Can scientists increase the rate of photosynthesis to help clean the air? Scholars complete an experiment determining net photosynthesis. Then, they apply knowledge from the activity to design their own investigations of the factors that...

What is coral bleaching? Tackle a trendy topic with a narrated animation. Through a combination of video and illustration, the narrator introduces viewers to a coral reef, then goes inside a coral polyp to show its symbiotic relationship...

Are you having trouble deciphering the Next Generation Science Standards on the website, or just trying to find the standards for your grade in a quick-and-easy format? If so, here is a free and easy-to-navigate app made with you in mind.

Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...

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 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...

Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

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...

Finally, a photosynthesis activity that outshines the rest! Young biologists perform an experiment that allows them to observe photosynthesis through the production of oxygen. The lesson, part of the K20 series, also includes a study of...

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...

How do you plan to approach standard LS1C, Organization for Matter and Energy Flow in Organisms? Avoid information overload with helpful advice in a short video. Topics include energy sources, relationships between organisms, and...

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

This is one super model interactive! Middle and high school science scholars examine scientific models through a simple resource. Guided, hands-on practice allows them to classify conceptual, mathematical, and physical models. Other...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

Seventy percent of the world's oxygen is produced through photosynthesis by phytoplankton, microscopic plants found in the ocean. Viewers learn about the complex process of photosynthesis with a video that covers both the light dependent...

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion questions.

View how autotrophs and heterotrophs use the energy of the sun to form the energy their cells need, ATP. Learners watch an informative video that details the processes of photosynthesis, learning where it occurs, what molecules are...

Life requires energy, for without it, you will die! Learners watch a video to see how organisms use free energy, gain knowledge about Gibbs free energy, and observe how free energy plays a role in both photosynthesis and cellular...

Take charge of your biology class by using this exciting analogy to relate the ATP process with batteries. Pupils use batteries and rubber bands to simulate the phosphate bonds between molecules in the body. They measure the distance in...

Take young naturalists on an exploration of the world's tropical rainforests with this extensive collection of lessons and activities. Whether its creating leaf and flower prints or investigating the absorption spectrum of chlorophyl,...
