Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Use whatever material floats your boat. Working in groups, scholars decide on a type of metal and a type of coating to use for building a boat. They test their creations by leaving their boats in a pool of water for several days before...

Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

Keep one's dream of becoming an engineer afloat. Learners apply the engineering design process to build a boat out of aluminum foil. They start with a square boat, then consider whether boats of different shapes would be able to hold...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Students research the innovative technology used in building the Allegheny Portage Railroad, and how it was applied to other projects. They discuss technological change and the effect it has on their lives.

Who said teaching a STEM lesson had to be challenging? Incorporate a career and technology-centered car build into your upcoming force lesson plan, and your class will be moving down the road in no time! Pupils practice...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Save the soup! Scholars devise a flotation device using straws, balloons, foam, corks, and other objects. A can of soup must stay afloat for at least a minute with this device—your dinner might depend on it!

How do you decide what sources are credible when researching online? Evaluate sources with a focus on researching health issues. After brainstorming common health concerns and how they would try to diagnose these problems, class members...

Students evaluate how volunteering helps others. In this philanthropy activity, students define what a volunteer is and brainstorm a group volunteer project to implement in the school. Students write an essay describing how volunteering...
