Pop Science Quiz: What happens to water when it reaches 0°C (32°F)?
Answer: It freezes!
But does water always freeze when it reaches 0°C (32°F)?
Believe it or not, water can sometimes be cooled to temperatures below its freezing point and still remain liquid. In this state the water is supercool.
How can this happen? In this activity you will create your own supercool water, and initiate its transition from liquid to solid. All while making a tasty snack!

Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged…

People often draw conclusions from a small number of observations, and use those conclusions to evaluate the likelihood that an event will take place. But how easy is it to draw the wrong conclusion based on those observations? Will your predictions be accurate if an experiment is only performed a few times? The objective of this project is to determine what happens when a test with two equally-likely outcomes is performed only a small number of times.
You can test this by flipping a coin. A…

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out.

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…

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…

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…

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)
