Do scientists really change their minds when presented with new evidence? Young scientists learn about two competing theories they need to decide between. They perform a simulation and have access to actual field data. Then, scholars...

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Young scientists know it is hotter along the equator, but why is it also rainier? Through the process of completing two experiments and a worksheet, scholars discover the answer is the intertropical convergence zone. First, they...

Most people rely on the ground under them remaining still and constant, yet the plates on the earth are constantly moving. A research-based STEM lesson asks pupils to research seismic data and tectonic plates. Then they create surveys of...

We name eras of human development such as the Stone Age, Copper Age, Bronze Age, and Iron Age after rocks and minerals, proving how important these are to daily life. The applied STEM unit encourages scholars to act as geologists...

This fresh resource explores the world's fresh water: where it can be found, and how humans use it. You might be surprised at the variety of domestic uses! Short, but sweet, this feature can be followed by a class discussion using the...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

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...

Pretty pictures of water droplets, clouds, and snow-covered mountains are the backdrop for information about clouds and precipitation. With 10 slides in all, viewers see how and where clouds form as well as what forms of water can fall...

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.

New ReviewHow do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

New ReviewHow do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

There are many interactions among living things and their surroundings. Scholars learn about Earth, the moon, and the sun and how they relate to the solar system by completing a reading. They also investigate basics of physical science...

Why is Earth so diverse? What makes it habitable for so many forms of life? An informative PowerPoint explains the important characteristics of Earth from geological history and atmospheric layers all the way to how and why weather...

The news reports on rising sea level, but how do scientists measure this rise? Scholars use NOAA data including maps, apps, and images to work through five levels of activities related to sea level. Each level in the series adds a new...

Young scientists explore climate change by taking a look at many different disciplines. They hear from scientists who study soil, clouds, ice cores, ocean temperatures, and more. Then, they search public databases to draw their own...

Do meteorologists and climate scientists use the same tools? The final lesson in a 13-part series on Exploring Energy compares and contrasts climate and weather. It describes the scientists who study each, the tools they use, their...

Winter, spring, summer, fall, and hurricanes? With the help of a video that is part of a larger Seasonal Science series, learn why hurricanes have a season all their own. Viewers integrate knowledge of the causes of hurricanes, factors...

What's in your water? And, why is water quality so important? Enhance your class's level of water appreciation through a lesson that demonstrates the necessity of water quality. Environmental enthusiasts explore the EPA's Clean Water...

Gorongosa National Park holds a fascinating and ever-changing landscape. What makes the water cycle in the park so special? Travel to Mozambique to learn more about the park using a short video. Content includes rainy season in the park,...

What does it mean to be a good steward? Middle school environmentalists learn to care for their state's waterways through research, a guest speaker, and poster activity. Groups must locate and learn more about a river basin and the human...

How has human activity affected Earth's watersheds? An action-packed lesson plan, part of the K20 series, examines water's ability to go with the flow regardless of what is in its path. Scholars build model watersheds, examine time-lapse...

Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

Water that leaves the oceans must eventually return. The animations in the final lesson of the four-part NASA series show the complex path water can take across landforms before returning to the ocean. Approximately one-third of the...
