Are Laminates Stronger?

Science Fair Project Idea

Scientific Method

If you love to hit the half pipe with your snowboard or skateboard, then you have tested the strength and durability of laminates. Laminates are sandwiches of different materials that are glued together in layers to give strength and flexibility to an object. In this experiment, you can test if laminating wood can make it stronger and able to support a heavier load. How much weight can it take before it breaks? Read more

Crazy Crystal Creations: How to Grow the Best and the Largest Crystals

Science Fair Project Idea

Scientific Method

Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals. Read more

Pinholes, Light and Aperture Size

Science Fair Project Idea

Scientific Method

Pinhole cameras are not just for grannies! Even compared to all of the latest technology, a pinhole camera still gets beautiful results. Find out how this very simple aperture design works to control the way light enters the lens of your camera. Read more

Soil Compaction

Science Fair Project Idea

Scientific Method

Have you ever had to dig a hole in really hard soil? It is a lot of work! In this science project you can make an instrument to test the soil and find out how compacted it is, before you dig! Read more

Go with the Flow: Model Rivers with Cornmeal, Sand, & Water

Science Fair Project Idea

Scientific Method

Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment. In this geology science project, you will… Read more

Dye Eggs Using Silk Ties for Egg-cellent Colors

Science Fair Project Idea

Scientific Method

Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! To do this, most people buy dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. You can dye eggs in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this science project, you will dye eggs with old or used silk ties… Read more

M&M Math

Science Fair Project Idea

Scientific Method

It has been said that, "Life is like a box of chocolates—you never know what you're going to get" (Forrest Gump in Forrest Gump, 1994). In this science project you can test the "Forrest Gump Chaos Theory" by using M&M's®, which are much cheaper than a box of chocolates. What if life is more like a bag of M&M's? Find out in this science project if some things in life are predictable by using the awesome power of statistics. Read more

Do the Eyes Have It?

Science Fair Project Idea

Scientific Method

Some people have a photographic memory and can memorize anything they see almost instantly! Wouldn't that make homework easy? Other people can remember almost anything they hear. Try this experiment to see which type of memory you have. Read more
