Physical activity is needed for maintaining normal bone strength and mass. But whether physical stress on finger bones during development leads to an increase in finger length, is something you will discover in this project not by...

Have you ever ridden on a Roller Racer or Plasma Car? These are ride-on toys that you move ahead by moving the steering mechanism back and forth. You've probably seen skateboarders "slaloming" on level ground to keep rolling, it's...

Everyone's used to the idea that people are either right-handed or left-handed for particular tasks. That is, one hand is preferred (or dominant) over the other for a particular task. Did you know that people also have a dominant eye?...

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether...

This is a project that illustrates the process of natural selection in action. You'll need access to a laboratory for working with the bacterial cultures used in this project.

In this project, you will estimate the circumference of the earth, using a method developed about 2,200 years ago, by Eratosthenes, a Greek mathematician and the librarian of the great library at Alexandria, in Egypt.

A project that requires you to play with a dog cannot be all that bad, right? This scientific experiment entails the respiratory functions of dogs. Learn the chemical and bodily processes going on within your canine companions...

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...

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,...

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...

Have you ever wondered how fun toys like Silly Putty, Gak, and Slime are made? These products are so much fun because of the properties of polymers, which make them delightfully bouncy, stretchy, sticky, moldable, breakable, hard, soft,...

DNA fingerprinting (also known as DNA profile analysis and DNA typing), is a method of distinguishing between individuals by analyzing patterns in their DNA. This project focuses on the first method of DNA fingerprinting to be developed,...

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.

For many kids, a day at the beach would not be complete without building a sandcastle. Have you ever wondered how it is that you can pack sand into a mold for a sandcastle? Do some kinds of sand pack better than others? This project will...

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...

This project investigates the phenomenon of apparent motion by making your own flip-book animations. This optical illusion experiment, while fun and short, will prove to be a very eye opening experience.

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

When biologists want to separate different pieces of DNA, RNA, or proteins they use a technique called gel electrophoresis. In this science project you'll build a gel electrophoresis chamber and use it to discover how many components are...

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this...

Geology and archeology are examples of historical sciences. Their practitioners rely on multiple methods for establishing dates and temporal sequences as they seek to construct a history from the available evidence. This project will...

Is an I-beam as strong as a solid beam of the same size? What if you include weight in the comparison: which beam has the greater strength-to-weight ratio? Would an I-beam be stronger than a solid rectangular beam of the same weight?...

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...

Graphical methods of data presentation are a key feature of scientific communication. This project asks the question, "What's the best way to compare the land area of states: a map or a bar graph?" You'll be measuring performance on two...
