Make a Speaker
In this activity, students will learn how an electromagnet works by making a simple one. Using this knowledge, students will design a diagram to make a working speaker using household materials. Then students will follow instructions on one method of making a speaker, and test their own designs to compare results.
The Origin Of The Word ‘Robot’
‘Robot’ was the brainchild of the Czech playwright Karel Čapek, who introduced it in a 1920 play.
Candy Corn In Space
Astronauts are allowed to bring special “crew preference” items when they go up in space. NASA astronaut Don Pettit chose candy corn.
Building A Solar House
Buildings that are called “green” or “environmentally sustainable” are designed to use energy as efficiently as possible. In Missouri, Washington University’s Tyson Living Learning Center achieves sustainability by incorporating green technologies in different ways, including the use of solar panels. In this activity, students will explore how solar panels work by building a simple circuit, a series circuit and a parallel circuit, using a solar panel to light a bulb and comparing which method yields the brightest light. Then students will build a solar-powered house using a shoebox, and test some variables to determine the most efficient way to harness solar energy to power a model home.
Explosive Science
In this activity, students will use household materials to investigate and explore how the release of carbon dioxide gas from a chemical reaction can cause a small-scale explosion. Students then will experiment with variables to determine which factors launch a film canister the highest.
Fun With Optics
In this activity, students will perform several experiments, using simple materials to explore the properties of reflection and refraction and how they work in telescopes.
Dean Kamen
He’s invented everything from an insulin pump to the Segway Transporter. He started the FIRST Robotics competitions for students. And now, he has his own television show.
The Once and Future Car
This week, news emerged of a self-driving car being researched by Google. We’ll look back at other ‘cars of the future’ and what happened—or didn’t happen—to them.
Happy Birthday, Buckyballs!
Twenty-five years ago this month, researchers first identified buckminsterfullerenes — chemical structures shaped like tiny carbon soccer balls.
