The Pasta Puzzle: How Much Water is Required to Cook Pasta?

Science Fair Project Idea

Scientific Method

A plate of spaghetti, meatballs, and marinara sauce is a delicious and comforting meal. It's also an inexpensive meal, because it only costs about $12 to feed a family of four. And it's easy to make when you're on the go and need to eat a quick, but healthy dinner. Just boil a big pot of water, throw in your favorite pasta, cook for 11 minutes, drain, and top with meatballs and warm marinara sauce. Quick and cheap! But sometimes it feels like forever when you are waiting for water to boil,… Read more

Motion Mania: Applying Physics to Hula-Hooping

Science Fair Project Idea

Scientific Method

Practice makes you better at most things, and knowledge makes practice so much easier! Can you swirl a circular toy called a hula hoop around your waist or arm? Is it hard? What knowledge can you apply to find ways that make hula-hooping easier? Physics! Yes, physics will help you determine what makes one hula hoop a winner and another a flop. In this project, you will create your own hula hoops, spin them, and draw conclusions. The road will then be open to your becoming a hula hoop expert. If… Read more

Conduct Galileo's Famous Falling Objects Experiment

Science Fair Project Idea

Scientific Method

Standing on a balcony near the top of the Tower of Pisa in Italy, a young scientist dropped two balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying to prove his theory that all objects fall to earth at the same rate, regardless of their mass. Was Galileo's theory correct? In this science project, you will get to test it out for yourself! Look out below! Read more

How to Extract Energy from Grass

Science Fair Project Idea

Scientific Method

Mowing the lawn is hard work, especially on a warm day. Not only do you have to mow the grass, but you also have to dispose of the clippings. Some people add the clippings to a compost pile in their yard, which is a great idea. But did you know that some grasses can be used as a source of energy? In this energy science fair project, you will learn more about a type of energy called biomass energy. You will grow different kinds of grasses and see which type of grass gives you the most biomass,… Read more

M&M Geometry

Science Fair Project Idea

Scientific Method

Have your parents ever found you munching on candy and asked you, "How much candy did you eat?" Instead of saying, "I do not know?" and getting in trouble, maybe you would rather say, "I ate precisely 10.7 cubic centimeters of candy, Mom." Make your parents proud of their candy-eating genius child (you) with this simple science project. Read more

Yogurt Cultures

Science Fair Project Idea

Scientific Method

Have you ever wondered how yogurt is made and what makes some yogurts different from other yogurts? You may have noticed that most yogurt containers advertise that the yogurt contains "live cultures." This means that there are living bacteria in the yogurt! These amazing bacteria can turn plain old milk into a yummy yogurt treat. In this science project, you will investigate whether the bacteria affect what the yogurt feels, tastes, and smells like by making your own yogurt at home! 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

Home Sweet Biome: How Do Plants Grow in Different Environments?

Science Fair Project Idea

Scientific Method

Have you ever looked around and noticed the plants and animals that grow in your neighborhood? Have you ever visited friends in another part of your city, state, or even another part of the country? Have you noticed whether the plants and animals where they live are similar to those growing near you? What would it be like to live where they do? Why do certain plants and animals grow in one area, but not in another? In this science fair project you will learn about biomes and how different… Read more

Slinking Slinkies

Science Fair Project Idea

Scientific Method

Want to do a project with a toy your parents, or even grandparents, might have played with? Slinkies are fun toys that also make great physics and engineering projects. In this science project you will investigate how changing the angle of an inclined plane affects how the Slinky walks down it. What angle will enable the Slinky to go for the best walk? Read more

Measuring the Moon's Brightness

Science Fair Project Idea

Scientific Method

Sometimes a full moon can be so bright, you can walk around in the dark without a flashlight. How much brighter is a full moon than the other phases of the moon? How is the brightness of the moon measured? Read more
