Do your parents ever get upset with you for "wasting" paper and ink from your printer? Maybe you wanted to print a comic you found online, or a whole bunch of pictures of you and your friends being goofy, or all the instructions on how to put together that really awesome LEGO® castle. But 20 pages of text and pictures later, your mom or dad is yelling at you. Why do they even care how much you print? And why do people say it is a "waste" of paper? Try this printer-saving science project to…

Animals have different levels of activity depending upon their habitat, metabolism and behavior. Diurnal animals are more active during the day. Nocturnal animals are more active at night. Being diurnal or nocturnal may have different advantages for different animals. For example, desert animals tend to be nocturnal so they can stay cool and escape the desert heat present during the day. What types of diurnal and nocturnal animals are common in your area? You can set out a small trap to…

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out.

Tests, homework, taxes, speed limits, sports: there's always the possibility of cheating. Design a survey to investigate attitudes about cheating. Are some kinds of cheating worse than others? Are there times when it is OK to cheat, or is cheating always wrong? Do people who admit to cheating have the same attitudes as those who don't?

Learning to play an instrument can be a lot of fun, especially when you can pretend to be a rock star as you learn! In this science fair project, you will study how your score in a music video game changes as you play and practice. You'll need a video game where you use a controller shaped like a musical instrument. Two examples include Guitar Hero and Rock Band, but there may be more! In these games, playing requires nothing more than a sense of the music's beat, and ridiculously fast fingers,…

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs.

A video camera records 30 "frames" or distinct images per second. (That's for an NTSC camera in the U.S. PAL cameras in other areas of the world take 25 frames per second.) You can use this fact to time events and measure speed. One student has used a video camera to measure the speed of an arrow shot from a bow. The following project can help you set up your experiment: Distance and Speed of Rolling Objects Measured from Video Recordings.

Get good photographs of the Moon showing lots of craters and count how many craters you find in a range of diameter classes. One useful source is the Consolidated Lunar Atlas (Kuiper et al, 2006). Make a histogram that shows the distribution of diameters. Most of these craters were formed during the first billion years of the Moon's formation, but you should confirm that this is true for the the Moon areas you've selected in your photographs by doing background research. Is cratering uniform…

Is soil structure an important factor in earthquake dynamics? Investigate soil liquefaction and how different soil types respond to earthquake movements. Are movements more dramatic in sandy/loamy or clay type soils? Which soil structures are most stable? Which are the most volatile? (MCEER, 2005)

There are three different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g., Handiwrap or Glad Wrap), polyvinyl chloride (PVC) (e.g., Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film) and polyvinylidene chloride (PVdC) (note: Saran Wrap used to be made with polyvinylidene chloride, but has switched to polyethylene. You will need to search for another brand that uses PVdC if you want to test it). Which of these materials is least permeable to…
