Using Kepler Space Telescope Data to Identify an Exoplanet

Science Fair Project Idea

Scientific Method

The Kepler space telescope is a retired space telescope launched by NASA to discover Earth-size planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched on March 7, 2009, into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki. After nine years of operation, the telescope's reaction control system fuel was depleted, and NASA announced its retirement on October 30, 2018. Designed to survey a portion of Earth's region… Read more

Volcanoes

Science Fair Project Idea

Scientific Method

The papier-mâché volcano is a real classic, but there are many other ways to make an even more exciting and interesting science project focused on volcanoes! To get started on your own volcano-based science project, you will want to first have an understanding of how volcanoes form. This is related to tectonic plates. The entire outer shell of the Earth, known as the lithosphere, is made up of tectonic plates that are constantly moving. There are seven or eight large tectonic… Read more

Water from Air: Experimenting with Dew Traps

Science Fair Project Idea

Scientific Method

Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams, reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find and a precious resource. In this environmental engineering science project, you will investigate one way that people living in arid regions can collect water inexpensively: dew traps. Read more

Have you ever noticed seagulls bobbing up and down on the ocean while surfers paddle forward to catch a wave? Maybe you remember floating on a lake, going up and down as a wave passed by, or the feeling of being swept ashore by a breaking wave. Water waves are fascinating. They come in all sizes, from a tiny ripple to monster waves that are ten meters high. You have seen them, but do you know what drives them, how they move across oceans and seas? In this activity, you will bring the… Read more

Weather and Climate in Your Neighborhood

Science Fair Project Idea

Scientific Method

Do you live in an area where the weather changes a lot from season to season throughout the year? Or do you live in a place where the weather stays pretty much the same all year long? How dynamic is the weather, and how does it compare to climate? In this experiment you can use the Internet to conduct your own investigation about how climate and weather in your local area change over time. Read more

Weekly Science Project Idea/Home Science Activity Spotlight: Circus Science

Blog Post

In this week's spotlight: a pair of projects that put your understanding of balance to the test! What makes some things topple and other things stable? Use marshmallows and wooden sticks to explore how the distribution of an object's mass determines how the object will balance. You can investigate using these science project and activity procedures: Circus-Trick Science: How to Balance Anything (full Science Buddies Project Idea) Circus Science: How to Balance Anything… Read more

What is the Woolly Mammoth's Closest Living Relative?

Science Fair Project Idea

Scientific Method

Woolly mammoths shook the ground of ice-age tundras for millennia, living next to saber tooth tigers and prehistoric man. Although they have been extinct for thousands of years, scientists continue to learn more and more about this mighty animal. Some of the most exciting new research is being produced by looking at DNA extracted from the hair and bones of woolly mammoths entombed in ice. In this genomics science fair project, you will use bioinformatics tools to determine the woolly mammoth's… Read more

Where's Waldo Science: Weekly Science Project Idea/Home Science Activity Spotlight

Blog Post

In this week's spotlight: a pair of projects that investigate the science behind visual search. When you are looking for a specific car in a crowded parking lot, what makes it easier or more difficult to spot the car? What if you are looking for your keys, someone in a crowd, or something specific on the shelves at the grocery? Do you enjoy puzzles and seek-and-find style books and games that make a game or visual brain teaser out of "finding" something that is hidden in plain sight. like… Read more

Which Liquid Works Best for Evaporative Cooling?

Science Fair Project Idea

Scientific Method

When we get hot, we sweat. Sweating helps cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes using what are referred to as swamp coolers. In some cases, these coolers may be more energy-efficient than traditional air conditioners. In this chemistry science fair project, you will find out which liquid works best for evaporative cooling.

Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (like in a lamp with a single light bulb) to very complex (like in a computer). Try this project to build your own simple circuit and use it to test which common household materials conduct electricity. Read more
