Get Rid of Those Leftovers: How Much Organic Waste Can Composting Worms Eat?

Science Fair Project Idea

Scientific Method

What happens to the food leftovers in your home? Do they go in the trash? Down the garbage disposal? Or get gobbled up by the family dog? Food leftovers are a type of organic waste, a waste that comes from a plant or animal. Organic waste—like table scraps, agricultural waste, and human and animal waste—is biodegradable. This means, it can be chemically broken down by bacteria, fungi, or other living organisms into very small parts. Figure 1. This… Read more

Gigantic, Invisible Triangles: Measuring Height (or Altitude) with an Inclinometer

Science Fair Project Idea

Scientific Method

If you've ever wondered how tall that bridge is, or how high your kite was, then this could be a good project for you. You'll learn how you can use the mathematics of right triangles to measure the height of an object with two measurements that you can make on the ground. Read more

Golden Rules of Photography: Family Science Spotlight

Blog Post

Try this hands-on science experiment to learn about the golden rules of photography and improve your photo compositions. When you take a photo, do you put the subject right in the center? What happens to the same photo if you move the subject to the right of the frame, or to the left? These are questions a photographer asks herself every time she gets ready to snap a photo. Where should the subject "go" in the frame? In making this decision, a… Read more

HAMing It Up with the Astronauts

Science Fair Project Idea

Scientific Method

Have you ever wished you could talk to an astronaut on board the International Space Station? You're probably thinking "yeah, like NASA would ever let you do that!" Actually, they will! The International Space Station (ISS) is equipped with its own HAM radio station. The ISS HAM radio station allows astronauts, cosmonauts, and space mission specialists from different nations who are on board the space station to talk to people back home on Earth. Anyone with an amateur radio license is… Read more

Harmful Algal Blooms in the Chesapeake Bay

Science Fair Project Idea

Scientific Method

Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to use archived data from continuous monitoring stations on the Chesapeake Bay to study how water quality measurements (dissolved oxygen (DO), salinity, temperature, pH, turbidity, and total chlorophyll) change before, during, and after harmful algal blooms.

Do you love to hear the pulsing chirp of crickets as you fall asleep? It is an unmistakable sound. Some people find the sound pleasing and peaceful, but other people find the sound loud and annoying, especially if a cricket happens to get inside a home to escape the cold. However you feel about crickets, their chirps hold a surprising message — they can be used to predict the temperature! In this science activity, you will investigate how the chirps of these tiny creatures can be used… Read more

Heart Health: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a human biology and health project that puts an important question to the test: if you exercise regularly, does your heart recover from exertion more quickly than if you don't exercise often? The heart pumps faster during exercise, which helps to keep the heart healthy. It is good to exercise frequently and to raise your heart rate into its target heart rate zone during exercise, but how long does it take for the heart to return to its normal… Read more
