Which Kind of Wood Burns Slower?
Science Fair Project Idea
Scientific Method
Do you ever go camping with your family and roast hot dogs and marshmallows over a campfire? If you want your campfire to burn long into the evening, what is the best wood to use? Do research on the necessary conditions/materials to sustain a fire and on the properties of different types of wood. Which properties do you think will be most important for determining how fast the wood burns? For example, how do you think density would be related to burning rate? Why? Measure the density and… 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
Alternative Sources for Paper Fiber
Science Fair Project Idea
Scientific Method
If you're interested in arts and crafts, you might like this project. It uses several alternative, renewable sources of fiber to make paper, and compares the resulting papers for strength and writing quality. Read more
One Bad Apple Spoils the Whole Bunch: An Experiment on the Plant Hormone Ethylene
Science Fair Project Idea
Scientific Method
We have all heard the old saying, "One bad apple spoils the whole bunch." Due to the production of the plant hormone ethylene during the ripening process, this saying proves true! This experiment will investigate the role of ethylene in the process of fruit ripening. 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
Fresh Whipped Cream That Lasts
Science Fair Project Idea
Scientific Method
Fresh whipped cream is the final touch for many delectable desserts. One issue with fresh whipped cream is that it has to be used soon after it is made, especially if it is at room temperature, or it starts to collapse into goo. This is a problem for its use in frostings or inside pastries as filler. Whipped cream can be stabilized by adding unflavored gelatin. Stabilized whipped cream can be used at room temperature and it has a much longer life. But how much gelatin is just right? Try… Read more
Turning Mushrooms into Environmentally Friendly Packaging
Science Fair Project Idea
Scientific Method
Have you ever questioned the packaging of an item in a plastic container, secured in a plastic mold, that also slides into a plastic box, or a small item packed in twenty times its volume of polystyrene noodles to keep it from breaking? In this project, you will explore if mycelium composite material, an eco-friendly material obtained from organic waste and mushroom roots, can serve as a viable eco-friendly packaging alternative. Packaging material made of foams and plastics (Figures 1 and 2)… Read more
Spare a Watt, Save a Lot
Science Fair Project Idea
Scientific Method
Do you know how much power is used every day in your home? What you might not realize is that making simple changes can save you energy, power, and money. What would you do with extra money? Put it in the bank or get something that you really want? In this science fair project, you will investigate the different uses of electricity in your home and determine if there are simple changes that you can make to save energy and money. Read more
Processed Cheese, Please! Get Your Grilled Cheese Oooey Gooey Instead of Oily and Gloppy
Science Fair Project Idea
Scientific Method
A delicious and quick lunch is a cup of tomato soup and a grilled cheese sandwich. Biting into the toasty, butter-soaked bread and gooey cheese is very comforting. But what makes the cheese melt so nicely? Do all cheeses melt this way? In this cooking and food science fair project, you will experiment with making and determining the best recipe for processed cheese. Read more
How Can Your Faucet Save Water?
Science Fair Project Idea
Scientific Method
One way to save water is to turn the faucet off while you brush your teeth. But did you know that there are products that can help save water even while the water is on? In this experiment find out how low-flow faucets and aerators work to reduce the flow of water. How much water can you save? Read more
