Here's a project with practical applications for homes with a wireless network. This project shows you how to build and test parabolic reflectors for the transmitters on your network. You may be able to increase the range of your...

Here is a basic project for investigating enzymes that prevent gelatin from solidifying. This way you can understand why it is some fruits are not recommended for inclusion when it comes to making gelatin.

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead...

An interesting approach to science projects where students are challenged to create complex machines that do very simple jobs, e.g., opening a door. Offers four ideas for projects.

We know that plants, and even bouquets of cut flowers need water to survive, but we often do not think about how water moves within a plant. In this science project, you will use colored water and carnations to discover how water travels...

Explore three science fair project samples about birds, stain removal, and keeping it cool. See how the report is written after the investigation is complete.

Examples of the effect of bending stresses on flexible rods could include a large tree bending over to the ground, or a fishing pole bending till it snaps. Scientists actually study this phenomenon and discover ways to prevent breakage,...

In this science project, you can investigate how submarines use stabilizing fins to move forward. Exploring friction and buoyant force you will get closer to understanding how these large ships function. Research resources are included...

Washing your hands is the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. This science project investigates which...

There are over 58 million overweight cats and dogs in the United States alone. In this science project you will determine what percentage of the pets you know are overweight and how their weights compare to weight of pets throughout the...

Whether a chick can breathe inside its shell is an interesting question. Every animal needs oxygen to survive, so the chick must get air somehow. Try this science project to discover if the pores in a chicken egg shell allow water to...

Chances are, you have several materials around your house made of gelatinized materials. Gels are used in all kinds of products and materials: pudding, diapers, insoles, packaging, ice cream, toothpaste, and much more. In this project,...

As if sniffles and clogged sinuses are bad enough, everything seems to taste bland and flavorless when we are sick. Gather up a few volunteers, hit the kitchen, and try this experiment to find out if there is really truth to the idea...

All animals have a genome, but do they all have genome projects? Find out which animals are currently having their genomes sequenced and how much we know already by performing some simple bioinformatics data digging.

Puppies prove to be a fun and useful aid in this adorable experiment! By having access to, and measuring a puppy's body dimensions over a period of weeks or months, you can discover if segments of canine anatomy develop at different...

Ever try to tear a telephone book in half? Even though you can easily rip one or a few pages to shreds, the entire phone book has strength in numbers and holds together. This project is an introduction to measuring and comparing the...

The goal of this project is to measure the effectiveness of different sunscreen products for blocking ultraviolet-A (UVB) and ultraviolet-B (UVB) rays from sunlight. This project shows you how to use a UV detector to measure rays of light.

Want to do a project with a toy your parents, or even grandparents, might have played with? Slinkies are fun toys that also make great science fair projects. In this experiment you can build an inclined plane to compare the walking speed...

People often draw conclusions from a small number of observations, but how easy is it to draw the wrong conclusion? Here is a simple project that shows the importance of making enough observations before making a prediction.

This project shows how mathematical probability sometimes contradicts our intuition. Despite the fact that there are 365 days in a year, if you survey a random group of just 23 people there is a 50:50 chance that two of them will have...

Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow.
