Young geologists piece together the puzzle of plate tectonics in an earth science lesson. Given a physical map of the world, they search for land formations that indicate the location of different types of plate boundaries.

Bring together a study of two major scientific topics with a lesson on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn...

Take it all the way back! Young scientists discover the changes that took place from the time Earth became solid to present day through an interesting interactive. The resource guides users through key events that have shaped our world...

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...

Why is diversity in biology so important for an ecosystem? Explore biodiversity, evolution, and natural selection with a presentation for your biology class. It features clear information, activities for further understanding, and...

The most important chemical process on Earth is photosynthesis. Scholars explore the changes in the gases in our atmosphere as life on Earth developed. They create a model of photosynthesis and consider simple questions.

For as small as they are, there sure is a lot of information for young scientists to learn about bacteria. Help simplify the subject with this instructional presentation that explores the structure, nutrition, and reproduction of...

Prompt scholars to discover the expansion of the universe themselves. Using photographs of other galaxies, they measure and then graph the size and distance of each. Finally, they draw conclusions and prove the universe is...

Here's a topic classes can really dig—the fossil record. Use the well-organized and thoughtful road map to take eighth graders back in time to unearth the answer. Learn how our climate has changed, and how organisms have...

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion...

The Milky Way gets great reviews on Trip Advisor — 100 million stars. The activity allows scholars to rethink their assumptions and prior knowledge. Pupils observe a set of two lights at equal distance and brightness, but they believe...

Scholars take off on an interactive spaceship to explore a historical timeline of the big bang theory. They learn about the evolution of mammals and humans, the formation of stars and planets, and the chemical composition of the early...

Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final lesson of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids. Scholars...

Welcome to Biology! Introduce pupils to a subject conceptualized by Aristotle in 300 BC through a presentation and worksheet. It covers the themes of biology, characteristics of life, the scientific method, microscopes, and measurements.

Earth didn't always have oxygen, so what caused the change that allows humans to live here? Learn about the change in O2 levels throughout geological history through an interactive graph. Each section offers greater detail on the changes...

When crocodiles close their mouths, you still see their teeth, but when alligators close their mouths, their teeth are hidden. Learn more about these reptiles and their many evolutionary cousins in a fact-filled presentation. It...

Mammals include more than 4,000 species and represent the most dominant land animals on Earth. Scholars learn about the large variety of mammals, including orders unfamiliar to most. The presentation highlights the characteristics and...

Do you think you know better? Become a scientist and prove it. Scholars review the evidence for two different theories of the origins of the universe. They notice the empirical observations as well as the inferences to determine which is...

Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...
