Help young scientists piece together the theory of plate tectonics with this comprehensive collection of materials. Whether your are looking for worksheets, hands-on activities, or assessments, this resource has everything...

Each of the Earth's spheres interacts with the other spheres in predictable ways. Young scientists explore these interactions through a hands-on activity, graphing, and watching a video. They summarize their knowledge in a video or...

In 150 BC, Seleucus of Seleucia theorized that the moon causes the tides. Scholars learn about what causes tides by studying the interactions of gravity between the sun, moon, and Earth. They use technology to formalize otherwise...

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.

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...

What can layers of rock teach us about the climate? Young scientists solve a mystery about who stole a cookie by applying the law of superposition. Then, they apply the same concept to solve a more difficult mystery, trying to determine...

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.

Celebrate the arrival of spring with this fun primary grade science unit. Engaging young scientists with a variety of hands-on activities and inquiry-based investigations, these lessons are a great way to teach children about...

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...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

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...

Can you name the three planets with rings in our solar system? Everyone knows Saturn, many know Uranus, but most people are surprised to learn that Jupiter also has a ring. The third in a series of six teaches pupils what is around...

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...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Space diving refers to the act of jumping from outer space and falling through Earth's atmosphere before parachuting to land. Scholars learn about this extreme activity and study the layers of the atmosphere they must conquer in the...

In May of 1981, the Winter Park Sinkhole in Florida first appeared and is now referred to as Lake Rose. Scholars learn about the causes of sinkholes through an inquiry project. Then, they analyze recent data and draw conclusions to...

Young scientists observe deforestation from satellite photos and discuss the importance of forests to the global environment. They then simulate a plot of forest when farmers move into the area over the course of seven years. Finally,...

The moon takes just over 27 days to orbit around Earth. Young scientists position themselves as the earth as they rotate around the sun and hold the moon. This allows them to observe the patterns and phases of the moon.

Get a taste of what the study of the universe entails! A PowerPoint presentation highlights the important aspects of studying astronomy. Packed with facts and images, the presentation is sure to get your class excited about their universe.

In this second lesson plan of the series, pupils learn to observe similarities and differences in photos of the sun and record them in a Venn diagram. Then, small groups practice the same skill on unique images before presenting...

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...
