Scientific Method
French fries, hash browns, mashed potatoes with gravy, potato latkes, there are so many things to make with the humble potato. The potato is a tuber from the perennial plant Solanum Tuberosum of the Solanaceae family. There are actually about 5,000 varieties of potatoes, but most of them can be traced back to the original potato from southern Peru. This single ancestor originated more than 10,000 years ago. In addition to being high in vitamins and minerals, potatoes have a varying amount of… Read more

Do you like to look up into the night sky? There are so many stars, it can be mind boggling! Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. Do constellations change more in one hour, one day, one month, or one year? Read more

Scientific Method
Up, up, and away! If you have ever made a wish and blown the fluff of a dandelion, you have witnessed how some plants are adapted to spreading their seeds using the wind. The tiny, furry parachute allows the seeds to be picked up by the wind and to be carried far away from their parent plant. In this experiment, you will make models of seeds and fruit to investigate dispersal by wind and to evaluate the relationship between the structure of the seed and its ability to be dispersed by the wind.

Jpeg, bmp, gif, tiff ... do these just look like words that you and your friends might make up for your own secret language? They are actually just a few of the file formats (which means "types") that you can use to save your favorite photo on your computer. But does it matter which one you use? Try this simple science fair project to find out and you'll never choose the wrong one again! Read more

Scientific Method
Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events! Read more

Scientific Method
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar or salt) that are dissolved in the water? Do they boil off too, or do they stay behind? Read more
