Can Gaming Help You Score Better in School?

Science Fair Project Idea

Scientific Method

Can computer games be used to educate? Pick a game that incorporates educational material. There are a variety of educational computer games on the market in the areas of math, history, science, and language, as well as many simpler versions free on the Internet. Make up a test based on the subject area covered by the computer game. Have your volunteers take the test before and after playing the game. Does playing the computer game improve people's score on the test? Read more

Can Mulch Reduce Garden Water Requirements?

Science Fair Project Idea

Scientific Method

Divide a part of your garden into two equal plots, with each plot receiving equal amounts of sun. Cover one plot with two inches of organic mulch, such as compost or ground bark. Leave the other plot uncovered. Use the same amount of water for each plot for two or three weeks. At the beginning of the experiment, and at one-week intervals, dig down and check the soil in each plot for moisture content. Which plot holds water better? Which plot shows better plant growth?

Can Video Games Be a Form of Exercise?

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 Make a Happy Song Sad?

Science Fair Project Idea

Scientific Method

Are there some songs that always make you feel sad when you hear them? How about "Scarborough Fair," George Gershwin's "Summertime," or the Beatles' "Eleanor Rigby"? All of these songs are in a minor key. Minor and major scales both use the same number of notes and include the same number of semitones (also called half tones), but in a different pattern. Some musicologists (people who study music) maintain that minor-key songs are more likely to be perceived as sad, while major-key songs are… Read more

CD Burning: Take it to the Edge

"Surprise Glacier" © 2010 Jiuguang Wang Do sea levels rise when ice melts? Does it matter whether the ice is on land or in the ocean? Students design an experiment to find out. They collect data, graph their results, and interpret their findings. Along the way, they learn about density, displacement, and climate change. Read more

NGSS Performance Expectations:

5-PS1-2. Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Color Profiles

Science Fair Project Idea

Scientific Method

Did you know that the same digital photo you see on a computer monitor may not look as good in print? When it comes to color profiles, there are a lot of options: RGB, CMYK, grayscale and indexed color! How do you choose the right color profile for the job? Read more

Color Saturation

Science Fair Project Idea

Scientific Method

Lively, vivid colors can add pizzazz and turn a dull photo into a work of art. Learn how changing the saturation levels of the colors in your photo can really make it pop! Read more

Does your family have jellied cranberry sauce with Thanksgiving dinner? Jellied cranberries are thick and retain the shape of the mold in which they are placed, which might mean a turkey-shaped mold or even the shape of the can if you use a canned version. Taking a bite of jiggly jellied cranberries can be a fun addition to a delicious meal, but cranberries can also be served as a liquid-like sauce. Both versions use the same ingredients, so what makes one turn into a gelatin while the other… Read more
