Science Fair Project Idea

Scientific Method

Have you ever played a video game that made you break a sweat? Or pant a little bit? The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Do you think these video games can be considered exercise? This science fair project will help you find out! Read more

Can Water Plants Be Used to Determine Water Quality?

Science Fair Project Idea

Scientific Method

Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

Can You Crowdsource a Better School Environment?

Science Fair Project Idea

Scientific Method

How can you motivate students and teachers to make positive changes in their school? Why not try using what is in everyone's pocket—a smartphone! With this project you'll try your hand at harnessing the power of crowdsourcing and mobile technology by creating an app that motivates users to change their school for the better. Do not worry about the app creation, the MIT App Inventor tool makes that part easy; the instructions provided here will lead you through it step-by-step. Will your… Read more

Have you ever wanted to make something disappear (maybe your homework!)? In this activity we will take advantage of the way your eyes and your brain talk to each other, to make colored dots seem to appear and disappear (sorry, it probably won’t work on your homework)! Read more

Candy Confusion: Can Small Children Mistake Medicine for Candy?

Science Fair Project Idea

Scientific Method

Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out. Read more

Candy Corn Geodesic Dome

Blog Post

A classic science (and geometry) project takes on Halloween tones with candy corn-colored candies, a few ordinary toothpicks, and a bunch of triangles. We are big fans in my house of the geodesic dome. We initially tried a bigger-than-expected version made from straws a few years ago. We had a great time putting it together—but it would not fit through the front door! Making a small-scale geodesic dome from gummy candies is a much easier and… Read more

Do you filter your tap water before drinking? Maybe at home you have a water filter on your faucet, in the fridge, or use special pitchers that have a filter unit in them. You have probably heard in commercials that these filters are supposed to make your water cleaner and safer to drink. But have you ever wondered what, exactly, these filters are doing and if the water is really cleaner in the end? Find out about the cleaning power of water filters in this activity; but for results you can… Read more

Carbon Filters and Adsorbing Science

Blog Post

Explore the science behind a carbon filter with a fun hands-on family STEM activity. Now you see the color... and now you don't! Water filters that use activated carbon can help "clean" water. You might be able to see the difference the filter makes, but not always. In this week's family science activity, families can explore the way these filters work with a colorful hands-on project that makes stripping the color from a sports drink or colored soda… Read more
