How do the hydrophobic and hydrophilic regions of a protein affect its shape? Science scholars explore the molecular properties of protein molecules using a detailed interactive. The resource allows the user to rotate the protein, view...

As the reality of population decline across many species becomes real, pupils learn about the variables related to changes in populations. They complete a simulation of population changes and graph the results, then discuss limiting...

Communication involves the visual, auditory, olfactory, and tactile senses. Scholars observe groups of animals communicating through multiple senses. They note and learn why different species use different senses depending on their...

Can you visualize one billionth of a meter? It's not easy to understand the scale of a nanometer. Learners use a hands-on lesson to develop an understanding of the size of a nanometer in comparison to common objects. They walk away with...

Scientists use morphological, physiological, and molecular information to continually revise organism classification. Scholars observe and learn about 20 shells. Then, they work to sort and classify the shells, building a taxonomy based...

Each genetic disorder has its own story to tell. A research-based lesson asks individuals to investigate a genetic disorder using scientific web resources. Guiding questions ask them to explain the mode of inheritance and the effects of...

Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

Plants provide humans with food, shelter, and medications. Scholars gain a better appreciation for plants after learning their functions, divisions, and early ancestors. Each sub-topic includes slides highlighting vocabulary and...

Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

Scientists noticed animals with backbones share similar bone structure despite having different forms, such as fins, arms, and wings. Young scientists gain an appreciation for evolution by understanding the history of the theory. They...

Based on DNA, fungi relate more closely to animals than to plants. This new scientific knowledge shifted the world view of scientists and opened up new classifications. Viewers learn about fungi's place in evolution, in the tree of life,...

Can an area with no soil turn into a forest? Scholars learn about the process of ecological succession using an interesting presentation. It covers both primary and secondary succession in the building of new ecosystems.

Water covers more than 70 percent of Earth's surface. Scholars learn about both freshwater and saltwater biomes in a simple presentation. They compare and contrast the differences in oxygen levels, food sources, and sunlight to better...

Many future doctors earn college science credit by passing the AP biology test while still in high school. Help young scientists prepare for the exam by studying past test questions. Each of the eight questions covers multiple topics...

Does a protein or DNA store genetic instructions for life? Follow the research from the 1920's experiments on mice through the 1940's experiments on bacteria to learn the answer to the difficult question. Scholars use an online...

When DNA research first began, it required almost an entire day to extract the molecules from a cell nucleus. Now it requires less than an hour. Scholars learn about the early theories of DNA with an online interactive, videos,...

In 1993, Phillip Sharp and Richard Roberts won the Nobel Prize for their discovery of split gene theory. Learn about the breakthrough with the help of an online interactive. Hear both scientists explain it in their own words, watch an...

Mario Capecchi requested funding for a new procedure targeting genes and was rejected. Four years later, after he proved it worked, the NIH apologized and funded his research. Use an online interactive to learn about his research and the...

Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

String the class along to help them understand large numbers. A multi-disciplinary lesson uses literature, science, and math to look at very large numbers. Pupils conceptualize how much a million is using literature before performing a...

Scholars explore the procedure for bacteria sampling in a virtual lab by first walking through a detailed step-by-step procedure of preparing the samples of raw milk and pasteurized milk, growing the bacteria, and comparing results....

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

Generate a buzz about circuits. Scholars conduct four activities to learn about electric circuits. They create dance pads that buzz and flash when stepped on, build hidden alarms, design creatures with eyes that flash, and take part in...

Carve out some time to learn about space-time. Young scientists use a remote learning resource to read up on the relationship between space and time. They consider the idea of relativity, see how objects with a large mass can bend space...
