More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

Use a vocabulary chart to introduce math functions. The class defines a list of mathematical vocabulary terms on a worksheet, as well as completes equations and expressions. They examine word problems and practice transcribing them into...

Bald eagles are opportunistic predators and eat fish as well as raccoons and other mammals. Pupils learn about bald eagle diets through a simple simulation and videos. They collect and analyze data to understand the adaptability of this...

What causes earthquakes? Second graders learn about stresses from plate movement with a set of hands-on activities. After tracing fault lines on a map with yarn, class members create a paper plate model of Earth to show its layers...

Learn about damage associated with earthquakes and materials that best withstand a quake. A lab engages class members in the experimental design and construction of sturdy structures that can endure various earthquake...

Oceans absorb half of the carbon dioxide and 80 percent of the greenhouse gases released into the atmosphere. Scholars learn how and why the oceans store heat more effectively than land and how they help mitigate global warming. Pupils...

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...

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...

Step into the role of a zoo director with several activities about animal training and running a zoo. Kids calculate the amount of food each animal needs, design a habitat for penguins, decide how to breed bottlenose dolphins, and train...

It is unknown if cloud cover increases in response to carbon dioxide levels changing, helping climate change slow down, or if cloud cover decreases, allowing Earth to warm faster. Part four in the series of five lessons has classes...

Young geologists get a glimpse beneath the earth's surface in this plate tectonics investigation. After first learning about the different layers of the earth and the constant movement of its plates, young...

Early humans crafted shelters out of whatever materials they could find. A one-question quiz asks learners to identify the type of bones used to construct the hut pictured in a display.

Can some plants make their own animal repellents? Science sleuths examine the properties of cinnamamide in pear trees using an case study about computational chemistry. The resource discusses how vital computers are to research, how...

Genetic information transfers through nucleic acids, making these the chemical link that connects people to their parents and grandparents. Viewers determine the importance of both DNA and RNA after observing the presentation. Key...

On September 26, 1991, four women and four men entered the scientific experiment, Biosphere 2; the doors were sealed for two years in order to study the interactions of a biosphere. In the activity, scholars explore biospheres by...

Analyzing and interpreting satellite data takes knowledge and patience. Through a detailed lab investigation, young scholars learn the process of analyzing this data. They use technology to create color images and maps from real...

Discover the connection between redox reactions and fuel cells. Collaborative groups build a Hoffmann Apparatus that demonstrates the electrolysis of water and then convert their models into a fuel cell. They use their fuel cells to...

Does your class know their planets? Implement an activity that has them describing the solar system, identifying properties of the planets, and placing them in order from their distance from the sun.

Represent motion with arrows and call them vectors! The lesson is a presentation that models the mathematics involved when determining a resultant vector. It addrssses motions that are parallel, perpendicular, and a combination of...

By the end of Harry Potter and the Deathly Hallows, we know Harry and Ginny get married, but what will their kids look like? This presentation introduces viewers to Punnett Squares and how to use them to determine both...

DNA analysis could be what saves some animals from extinction. An interactive lesson shows learners how DNA information proves variation among animals of the same species and how stakeholders use that information to make decisions. Easy...

Into each life some rain must fall, but how can that change rocks? Young geologists' understanding of weathering and erosion increases throughout the activities. The lesson includes five short activities to be completed...

Fourth graders explore how the landscape of the planet can be changed by different elements of wind, water, ice and chemicals through hands-on activities. They examine pictures of areas around town and discuss anything they think is out...
