Science Fair Project Idea

Scientific Method

Have you ever picked a flower and tried to make it stay alive in a cup of water? How long does that last? Do some flowers last longer than others? Why do you think that is? In this experiment, you will compare different plants to see which ones can regrow or regenerate after damage and learn why some plants are better at it than others. Read more

Extracting Onion DNA

Science Fair Project Idea

Scientific Method

In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Technicolor Shadows: Lessons in Light and Color

Science Fair Project Idea

Scientific Method

Is that right side of your brain yearning to express its artistic side? This is a project that beautifully blends art with science. Learn about light and colorful shadows in these experiments where you mix and match various colors of light to create a mini light show and shadow wall. You might be surprised at the colorful hues you'll find lurking in the shadows. Read more

Ocean Bioluminescence: Investigate When and How Dinoflagellates Glow

Science Fair Project Idea

Scientific Method

Imagine the ocean water turning bright red or seeing ocean waves glowing a beautiful blue color. Sounds impossible—but it is not! Red tides and glowing waves are caused by microscopic organisms living in the ocean called dinoflagellates. Some dinoflagellates have the ability to produce light through a process called bioluminescence. When and how do these organisms glow? In this science project, you will investigate how changing the dinoflagellate's exposure to light and dark affects its… Read more

Archimedes Squeeze: At What Diameter Does an Aluminum Boat Sink?

Science Fair Project Idea

Scientific Method

Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

Cosmetic Science: Testing Lip Balm Recipes

Science Fair Project Idea

Scientific Method

Did you know that cosmetics companies employ teams of specialized scientists to develop and test each new line of makeup, perfume, lotion, or soap? This science project lets you be the cosmetics scientist. You will create your own lip balm right in your kitchen using a short list of ingredients, then test it, and follow up with some creative cosmetics science of your own! Read more

Try the Mythbusters' "Phone Book Friction" Experiment at Home

Science Fair Project Idea

Scientific Method

Have you ever heard that two phone books with the pages interleaved are impossible to pull apart? This might seem crazy, right? It is not that hard to slide a sheet of paper off the top of a stack of paper. How much friction can there really be between sheets of paper? In this experiment, you will use pads of sticky notes instead of phone books. How much weight can they support when you interleave the pages? Do you think you will be able to pull them apart by hand? The results might surprise… Read more

Fighting the Flu: How Your Immune System Uses Its Memory

Science Fair Project Idea

Scientific Method

Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and… Read more

Make an Origami Robotic Gripper

Science Fair Project Idea

Engineering Design Process

Do you like making paper airplanes? What about origami animals? Have you ever thought about making a paper robot? In this engineering project, you will make a three-dimensional robotic gripper that starts out as a single flat sheet of paper! Try it out—see what objects you can pick up with the gripper, then see if you can improve the design. Read more

Enzyme-Catalyzed Reactions— What Affects Their Rates?

Science Fair Project Idea

Scientific Method

Enzymes speed up chemical reactions by factors of at least a million. Now that's acceleration! This project investigates how temperature affects how fast these enzymatic reactions occur. Read more
