Oceans represent more than 80 percent of all habitats, yet we know less about them than most other habitats on the planet. The instructor introduces the epipelagic, mesopelagic, bathypelagic, twilight, and midnight zones in the ocean....

Take your science class on a hypothetical field trip to Mars with an engaging astronomy lesson. After first learning about NASA's Mars rover missions, young scientists plan their own scientific investigations of Earth's...

Nature provides density columns in the polar regions that provides food for many animals. Young scientists build their own density columns with water in order to answer analysis questions. Through a slideshow presentation, scholars...

Dig through the layers for a better understanding of fossils. Scholars learn that fossils form in layers of sedimentary rock. Pupils arrange virtual layers to show the fossil record of different species. Once the layers are correct, they...

Fascinate young life scientists by showing them how their brain learns. By using prism goggles while attempting to toss bean bags at a target, lab partners change their outlook on the world around them, producing amusing results....

When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....

Develop an understanding of the universe. Learners answer 10 multiple choice questions about several topics in astronomy. Questions contain information about the age of the universe, gravitational attraction, galaxies, planets and comets...

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

Interestingly enough, movement is not a characteristic of living things. The first activity in a series of 20 introduces learners to the concepts of living versus non-living things and then focuses on biologists and what they study....

Spread the word about seafloor spreading! Junior geologists prove Albert Wegener right in an activity that combines data analysis and deep ocean exploration. Learners analyze and graph fossil sample data taken from sites along the...

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

One ecosystem is home to numerous habitats—how diverse are they? Pupils interact with an online lesson to explore three habitats in a rain forest ecosystem. They discover connections between species and how they depend on each other for...

Not all dogs are the same just like not all finches are the same. An interactive online lesson helps individuals learn about the causes and limitations to biodiversity. The clickable sections describe the basics of the genetics of...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Middle and high schoolers study significant people who shaped the 20th-century history and are introduced to database tools. Researchers use the Internet to research five 20th century history makers. They write a short biography of five...

Winter, spring, summer, and fall—take the learning of the seasons beyond the elementary level to the middle school classroom. Curious learners begin by watching videos about the seasons and the rotation of planet Earth. Then,...

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

One of the key objectives of Europe's Copernicus Earth program is to monitor the temperatures of the oceans and seas on Earth. Young scholars learn the effects of different heat capacities through two experiments. These experiments...

A greenhouse provides additional warmth and protection to the plants inside, but what if the greenhouse gets too hot? Pupils discuss and experiment with the difference between natural and anthropogenic greenhouse effect. They measure the...

What can fossils tell us about periods of extinction? Young scholars interpret fossil layers to make conclusions about changes in life during different geological time periods. They analyze the fossils for abundance and diversity as well...

Why is arts education so important? It builds critical thinking, analysis and creative problem-solving skills. Learners review the life of Michelangelo Buonarroti, and then analyze his piece, The Pieta. After that, they'll sculpt a human...

One hundred metric tons of CO2 can accumulate in one acre of forest over time—that's a lot of carbon! In the activity, groups of middle school learners determine what makes forests important. They then solidify the concept by using a...

It is just magnetic. This resource presents the concept of Earth's and another planet's magnetic field and how spacecrafts detect them. Learners study a problem using magnetometers and participate in three experiments to come up with a...
