How do scientists and engineers control robots that drive around other planets millions of miles away? It's nowhere near as easy as driving a toy remote-control car here on Earth. In this activity you will experience some of the challenges you face when driving a "robot" that you can't see! Read more

Measles: How to Defeat a Debilitating Virus

Science Fair Project Idea

Scientific Method

Measles is one of the most contagious viruses in the world, but there are differences in how the virus can spread within communities. Some communities may be able to prevent the disease from spreading, whereas others could experience a rapidly spreading, overwhelming outbreak. How does immunity and vaccination in a population of people affect how measles spreads? To answer this, this science project can be completed using the Measles: Defeating a Debilitating Virus Notebook with… Read more

Measuring Density and Porosity of Sand

Science Fair Project Idea

Scientific Method

For many kids, a day at the beach would not be complete without building a sandcastle. Have you ever wondered how it is that you can pack sand into a mold for a sandcastle? Do some kinds of sand pack better than others? This project will show you how to measure the porosity of sand: how much air space there is in between the sand grains. Maybe you can use your knowledge from this project to help you make bigger and better projects with sand. Read more

Measuring Surface Tension with a Penny: Weekly Science Spotlight

Blog Post

What makes drops of water on a penny appear to pool together on the top of the penny as a large drop rather than run over the sides? Attraction of the water molecules holds the surface of the water together until the amount of water is too great and spills over the edge. This attraction results in surface tension—something we can see visually in the way the droplet may seem to hold together as a jiggly whole rather than flowing freely over the edges of a surface. You can see surface… Read more

Measuring the Speed of Moving Objects with Stroboscopic Photography

Science Fair Project Idea

Scientific Method

A strobe light can illuminate an entire room in just tens of microseconds. Inexpensive strobe lights can flash up to 10 or 20 times per second. This project shows you how to use stroboscopic photography to analyze motion. Read more

Measuring Vibrational Frequency with Light

Science Fair Project Idea

Scientific Method

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Read more

Mechanical Science Scissor Lift

Blog Post

Kids can experiment with physics and mechanical engineering at home or in the classroom by making a fun cardboard scissor lift. Explore Mechanical Science Simple devices and machines can be used to help solve everyday problems. A scissor lift is a device that can fold up compactly but can extend to a great length. This kind of device uses a system of mechanical linkages and can stretch out or contract with an accordion-like motion. In the Build a… Read more

Meteor Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a pair of astronomy science projects perfectly timed for this year's peak Perseids meteor shower activity. Most meteors that pass through the Earth's atmosphere burn up before they hit the ground. But what happens when a meteorite hits? In this pair of hands-on science activities, students and families experiment to find out how the size of a meteorite is related to the size of the resulting crater. Craters and Meteorites (full Science Buddies Project… Read more
