Upper elementary and middle schoolers study the case of the ivory-billed woodpecker, a bird that was once-thought to be extinct. Learners explore the responsibility of people to preserve habitats, and take care of the animals who live in...

How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

Could you determine longitude based on measuring time? Early explorers used a longitude clock to do just that. Scholars learn about early exploration and the importance of the invention of the clock. Then pupils build their own longitude...

The compass was first used in 206 B.C., but we didn't discover magnetic poles until 1263 A.D. Presentation begins with the history of magnetism before continuing on to magnetic fields, magnetic forces, electromagnets, currents,...

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...

Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

In this history worksheet, students use the questions to discover meaningful science and history connections. The worksheet is meant to be viewed online to access individual answers.

Ancient texts, like Homer's Odyssey, mentions navigating ships by observing constellations. Pupils learn about the link between history and astronomy as they relate to navigation in the Bronze Age. Scholars complete two hands-on...

Evidence shows the Vikings likely navigated by using a simple sundial to find their course. Videos, a short story, and discussion help bring this time period to life as they study European history with a hands-on experiment. Scholars...

Students explain the practical uses of robots. They interpret possible careers in robotics, apply the safety guidelines of robots, and develop a perspective of the use of robots. They empathize with the cultural issues of robots in work...

High school scientists build their own magnetometer and use it to map the field surrounding a bar magnet. Excellent background resources is included, as well as a diagram of how to build the magnetometer.

Help your class understand the importance of exploration using robots. with a resource that provides a short history of robotics as a lead into looking at Martian robotic exploration missions. The activity specifically looks at the...

Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...

Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...

Honing reading and communication skills through the theme of farm animals is the focus of this lesson. Students read a book about Scandinavian farm animals and complete prediction journal activities. They complete a worksheet about the...
