Trade has always been a global affair. Explore what global trade meant for ancient Mesopotamians, Egyptians, and Kushites using a collection of documents from the historic societies. By examining literary works such as the Epic of...

While much of prehistory is cloaked in mystery, ancient ancestors left evidence in DNA, languages, and materials from their time. Using photographs of items such as cave paintings and ancient tools, as well as maps of linguistic patterns...

What does a beautiful sunset have to do with the atmosphere? An inquiry-based lesson has learners make observations about the visibility and color of the sky during different time periods. They then relate their observations to...

Sundials are more than just primitive clocks. Learners build their own sundials to study the location of the sun across the sky throughout the day. They use shadow evidence related to their sundials to make conclusions about solar movement.

Learners investigate the challenges of space communication with a kinesthetic modeling activity. Group members In space must communicate one word to other members on Earth while overcoming barriers such as distance, gravity, and physical...

Launch a great lesson exploring engineering design. Using a template, young scholars create rockets that can be launched from a straw. After analyzing the function of the rocket, pupils try to modify the rocket to enhance its function.

Don't leave your classes in the dark! An inquiry-based lesson has young researchers analyze the light intensity before, during, and after a solar eclipse. They use their data to make inferences about the solar energy available during...

Since you can't go to the comet, bring the comet to you. Young scientists build models of comets using everyday materials and then participate in a simulation of the interaction between the comet and other bodies in the solar system....

Changing one aspect of a mission impacts all the others. Learners consider a list of criteria as they develop their own science questions related to Mars and design a solution while considering all the important systems: computer,...

Learn what it takes to explore Mars in the comfort of a classroom. Individuals experiment with computer programming using a free online resource while learning about the factors affecting Mars Rover explorations. They create a...

Light, distance, and mathematics come together to help scientists plan for space missions. Groups examine the relationship between distance from the sun and light availability in a hands-on exploration activity. They model the inverse...

Video game designer meets science in a lesson examining the science of space exploration. Young learners use online software to create a video game that mimics the process of sample collection on Mars. They must make appropriate...

Trash collection can be a hassle, especially out in the ocean. The second of four parts in the Adrift in a Sea of Plastic unit has pupils research plastic trash islands in marine ecosystems. They investigate why they occur and potential...

Space is about 60 miles from the surface of Earth. Pupils make calculations to model that distance by stacking coins the appropriate height using scale. They then explore the distance to objects in space such as satellites and the space...

One way to study something is to try to replicate it. Young scientists do just that as they use solutions to recreate mineral structures on a dwarf planet. They make solutions with different types of salt, evaporate them, and observe the...

Balloons aren't just for parties! An inquiry-based lesson explores the idea of using balloons for space exploration. Learners become engineers as they attempt to control the ascent and descent of a helium balloon using different masses.
