Star light, Star bright: How Does Light Intensity Change with Distance?

Science Fair Project Idea

Scientific Method

Have you ever looked up at the stars at night and wondered how fast they were moving or how far away they were? By studying how the brightness of a star changes with distance, you can answer those questions. In this astronomy science project, you'll create a model of starlight and use a sensor app with your smartphone to discover the key relationship between brightness and distance. Read more

How Sweet It Is! Measuring Glucose in Your Food

Science Fair Project Idea

Scientific Method

You know that sugar makes food sweet, but did you know that there are different kinds of sugar? Sucrose is the granulated sugar that you usually use for baking. Another kind of sugar, which is found in honey and in many fruits, is glucose. In this science project, you will measure the concentration of glucose in a variety of foods. You will use special test strips that change color in response to glucose to measure the glucose concentration in different foods. Read more

The Chemistry of Clean: Make Your Own Soap to Study Soap Synthesis

Science Fair Project Idea

Scientific Method

Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more

Build Your Own Super-sensitive Electric Field Detector

Science Fair Project Idea

Scientific Method

Wouldn't it be nice to avoid those nasty electric shocks you get after you have walked around on carpet and then touch a doorknob? These shocks are caused by static electricity. In this project, you will build a super-sensitive charge detector to investigate the electric fields created by static electricity. The detector can sense invisible electric fields before you touch something and get zapped, so try this project to avoid the shock of shocks! Read more

Are Fingerprint Patterns Inherited?

Science Fair Project Idea

Scientific Method

Have you ever looked at two girls and thought they looked so similar that they must be sisters? What about a father and his son — have you ever seen a boy who looked just like how his father did when he was younger? We can often tell that two people are related because they appear to have several similar physical traits. This is because children receive half of their DNA — their genetic blueprints — from each parent. What about fingerprints — are they an inherited trait?… Read more

Design a Mini Solar Tracker System

Science Fair Project Idea

Engineering Design Process

How can you squeeze as much power as possible out of solar panels if you do not have a lot of space to install them? By tracking the sun! Keeping a solar panel pointed directly at the sun throughout the day can maximize the amount of power it produces. In this project you will design, build, and test your own miniature solar tracking system using a fun block-based programming language - no coding experience required! 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

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

Is It Ripe Yet? Build a Circuit to Detect Ripe Produce

Science Fair Project Idea

Scientific Method

When you go to the supermarket, how do you pick out ripe fruits and vegetables? You might look at their size or color, or feel them for firmness. That might be easy to do when you pick out a half dozen apples, but imagine if you had to examine thousands of apples growing in a field, or strawberries coming down a conveyor belt getting ready for packaging. Suddenly, it is a lot harder to do yourself! What if a machine could pick and sort the produce for you? In this project, you will address part… Read more

Squishy Robots: Build an Air-Powered Soft Robotic Gripper

Science Fair Project Idea

Scientific Method

When you think about robots, chances are they are contraptions that you have seen on TV, in movies, or even in real life — and they are usually made of metal. What if you could make a soft robot that could bend, twist, or squirm like an octopus or an earthworm? Researchers at Harvard University have done exactly that, developing soft robots made of rubber and powered by air instead of electricity. In this project you will use their designs to build a soft robotic gripper of your own. Read more
