Fungi Spores

Science Fair Project Idea

Scientific Method

Mushrooms are not plants, but are fungi. Fungi include mushrooms, molds, and lichen. They do not produce seeds to reproduce like some plants. Fungi produce spores, like more primitive plants do. The spores of a mushroom are contained in the tiny folds around the stem underneath the mushroom cap. Different species of mushrooms have different types of spores, with different colors and different patterns of folds. You can make mushroom prints by removing the stem from a mushroom and placing the… Read more

Gas and the Size of a Marshmallow

Blog Post

In this family STEM activity, students explore the science behind the size of a marshmallow. What happens if you add or remove air around a marshmallow? Families can see science in action by experimenting with stretchy, gooey marshmallows. Gas Inside and Gas Outside Marshmallows contain hidden gas that is trapped inside when they are made. Balanced by the gas (air) outside, marshmallows stay a certain size. But by manipulating the air surrounding a marshmallow, you can force a… Read more

Geology and Energy Resources

Science Fair Project Idea

Scientific Method

How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the National Geospatial Program to access, view, and download information from geospatial databases containing a broad spectrum… Read more

Geomagnetism

Science Fair Project Idea

Scientific Method

What is geomagnetism, and how does it affect the earth? Visit the USGS Geomagnetism program for more information about this invisible force (USGS, 2006). How is the earth's magnetic field patterned? Are the magnetic poles located at the exact North and South Pole? How can the fields be mapped on the Earth's surface? What is declination? Use the mapping tools to study changes in declination patterns over time. (USGS, 2006) Read more

Have you ever wondered how ancient people could lift very heavy objects, such as large stones, to build pyramids? A lever is a simple machine that can help people do just this. It can also help make other kinds of physical work easier by giving the user a mechanical advantage. Common examples of levers you might see around you are seesaws, scissors, wheelbarrows and even the your own jaw. Although all of these levers have the same functional parts, they vary in where the different components… Read more

Have you ever been helping in the kitchen and found yourself with a recipe that calls for egg whites? Do you use the egg shell to separate the egg yolk from the egg white? Instead of using the shell to separate them, you can use science! In this activity, you will use simple tools to explore how physics can help you do everyday tasks – such as separate egg yolks from egg whites. Read more

Go Wild! Try a Wildcard

Science Fair Project Idea

Scientific Method

Everybody's favorite card in UNO® is the wildcard—why? Because it can stand for any card you want! Your computer uses the same idea. A wildcard on your computer can stand for anything you want when you search. Do this science project to find out if using wildcards to conduct a search can help you find more of what you're looking for. Read more
