What's the Best Exposure Time for Sun Print Paper?

Science Fair Project Idea

Scientific Method

Did you know you can make paintings or drawings using sunlight? You can do it by leaving objects on top of special sun print paper until the light creates an imprint of the objects. How does this process work? How long should you leave the paper in the sun to get the best result? What does any of this have to do with the process of making the microchips that power our phones and computers? Try this project to find out! Check out this page for more science projects related to this process. Read more

Get Crafty — Create Your Own Durable Paper Doll

Science Fair Project Idea

Scientific Method

Through the ages, creative minds have made an amazing variety of paper toys, many of them delicate, beautiful, and inspiring. All too often, though, they do not withstand very well the wear and tear of play. This science project is your chance to fix that. You will make paper dolls with movable parts and study how the choice of materials influence the strength of the toy. Beginning with a strong design, you will finish by making a durable paper doll (or toy) with moving parts. Read more

Radiant Radish Seeds

Science Fair Project Idea

Scientific Method

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know that the sun gives off harmful radiation and heat. How much radiation and heat can a seed handle? Find out using some radish seeds, an oven, and your microwave! Read more

Distracted Driver: Do Distractions Affect Driving Video Game Scores?

Science Fair Project Idea

Scientific Method

Have you ever tried rubbing your stomach and patting your head at the same time? What about doing your homework or studying for your math test while watching television? It is tough to focus on a task when you are distracted doing something else, isn't it? In this science fair project, you will investigate how distractions affect your focus on a task, such as driving, by looking at how gaming scores are affected as you're talking on a cell phone or having a conversation with a friend.

Separating Mixtures: Can You Design a Device to Do It?

Science Fair Project Idea

Scientific Method

Have you ever looked in the kitchen cupboard and found a container of tiny white grains, but you were not sure if they were sugar or salt? They look very similar. How could you tell them apart? Well, you know that sugar and salt taste very different. Taste is actually called a property, and properties are used to describe and identify different materials. Properties can also be used to physically separate things. In this science project, you will use different properties to create a way to… Read more

What Is Home Sweet Home to a Bug?

Science Fair Project Idea

Scientific Method

If you had to choose between having your favorite dessert, going to a movie, or spending the night at a friend's house, which would you choose? This science project shows you how you can "ask" a sowbug (or pillbug) a similar question in order to learn about their preferences. Give it a try to find out what types of microenvironments these tiny crustaceans prefer. Read more

Fun or Frustrating?

Science Fair Project Idea

Scientific Method

Is winning correlated with fun? Pick a video game which has different difficulty settings, for example easy versus hard mode. Ask volunteers who have never played the game before to try it out. Some of them should use the easy mode and others should use the hard mode, this will ensure that you have a range in the amount of winning and losing among your volunteers. Keep track of how much each player is winning. Survey the volunteers to find out if they like the game. Do people who win more like… Read more

The Golden Rules of Photography

Science Fair Project Idea

Scientific Method

What is it that famous photographers do to make their images so pleasing to the eye? Find out if simple rules of geometry can make you a better photographer. Read more

Agrivoltaics: What Crops Grow Best Under Solar Panels?

Science Fair Project Idea

Scientific Method

We need farms for food, and we need solar panels for renewable energy. What if we could combine the two? Find out if certain crops can grow well under the partial shade of solar panels in this agrivoltaics science project. (Note: you do not need access to real solar panels to do this project. Any source of shade will work.) Read more

Creating a Video Game for Players with Visual Impairments

Science Fair Project Idea

Engineering Design Process

Do you enjoy playing video games? Do you like the challenge of reaching a difficult game level and scoring lots of points? Video games include many graphic elements that are great to watch, but did you know that not only sighted people enjoy video games? Blind and visually impaired players can also play video games by relying on sound cues — the pings, pops, bangs, and bursts of music that make a game fun or exciting. When building a game that will be accessible to differently abled… Read more
