Earthworm Castings — The Ideal Proportion in Soil for Young Garden Plants

Science Fair Project Idea

Scientific Method

Everybody knows that worms are good for the soil, but not everybody knows why. Here's a project that investigates just one of the ways earthworms improve the earth. Would earthworm castings (or earthworm manure) help your plants prosper and flourish? If so, how much should you use? Read more

Green Your PC: Help Your Computer Save Power

Science Fair Project Idea

Scientific Method

Is your PC an energy hog? Check out this science fair project to determine how much power your PC really uses, and if it is an energy hog, how you can reduce its appetite for energy. You'll learn how to profile and streamline your computer's power usage, while still enjoying every feature of your machine. Read more

Froggy Forecasting: How Frog Health Predicts Pond Health

Science Fair Project Idea

Scientific Method

Have you ever heard the expression "a canary in a coal mine"? In the 1900's and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous gases, so if the birds stopped singing, or got sick, then the miners knew to leave immediately, even if they felt fine. As it turns out, our froggy friends are also very helpful at signaling problems, not in mines, but in and around bodies of water. Try this… Read more

It's Hard Work to Work Harden! Learn How to Make Metals Stronger

Science Fair Project Idea

Scientific Method

It's easy to forget that metals are everywhere and in nearly everything. They are a part of our lives in so many ways that we hardly notice them. But just stop and think about it. We use metal spoons to eat and cook our food. Cars, bikes, and planes are composed of metals. Metals are in our furniture and part of your school supplies. Some people even have metal in the dental work in their mouths. Their strength and dependence is obviously very important. But what are metals? In this science… Read more

Is a Deleted File Really Gone?

Science Fair Project Idea

Scientific Method

When you delete a file, by accident or on purpose, is the information really gone? Can you get it back? If you accidentally deleted your five-page report for school, you may be hoping it is not really gone. On the other hand, if you do not want someone to get their hands on the goofy and unflattering pictures you and your best friend took while staying up late the other night, you probably hope the files you deleted are gone for good! Computer experts are often asked about file recovery.… Read more

Explore Perceptrons: A Simple Type of Neural Network

Science Fair Project Idea

Engineering Design Process

Have the phrases "machine learning" or "neural network" caught your interest, but you are not really sure how to use them in a science project? This project is a great place to start for beginners. You will learn about a very simple type of neural network—a computer program modeled after the human brain—called a perceptron. The perceptron can make a simple yes/no decision based on several inputs. You can "train" your perceptron to improve its decision-making abilities. Try it and… Read more

Wily Waves: Build an Oscillating Water Column to Extract Energy from Ocean Waves

Science Fair Project Idea

Scientific Method

The ocean is a wondrous force of nature. It affects the weather, and provides us with food and renewable energy to power our lives. How can the ocean provide us with renewable energy? One way is to extract the energy that is in the waves. There are many kinds of power systems that can be installed to extract energy from the waves, depending on the location. In this energy and power science project, you will build and test a simple model of an oscillating water column device to create power. How… Read more

Smashing for Mash: The Science of Making Memorable Mashed Potatoes!

Science Fair Project Idea

Scientific Method

What do you look forward to when the holidays arrive? Spending time with friends and family? Having lots of free time? How about the delicious food that comes out of the kitchen? You bet! What kinds of food do you have on your table during those special times of the year? For many people, mashed potatoes and gravy are usually on the holiday menu. Whether light and fluffy or smooth and silk-like, mashed potatoes are very satisfying. What is not satisfying is when the cook makes a mistake in… Read more

Get Rid of Those Leftovers: How Much Organic Waste Can Composting Worms Eat?

Science Fair Project Idea

Scientific Method

What happens to the food leftovers in your home? Do they go in the trash? Down the garbage disposal? Or get gobbled up by the family dog? Food leftovers are a type of organic waste, a waste that comes from a plant or animal. Organic waste—like table scraps, agricultural waste, and human and animal waste—is biodegradable. This means, it can be chemically broken down by bacteria, fungi, or other living organisms into very small parts. Figure 1. This… Read more

What's the Best Way to Guarantee Fresh Bread?

Science Fair Project Idea

Scientific Method

Have you ever bitten into a slice of bread only to find that it no longer seems fresh? Instead, it has the firm, undesirable texture that comes about when the bread is going stale. Chemically, what happens during the staling process? Can it be reversed (at least temporarily)? Do some background research to answer these questions and then apply those answers to one (or more) of the following experiments to find the optimal state to keep your bread fresh. Experiment 1: What Temperature Keeps… Read more
