Science Fair Project Idea
Scientific Method
Here's a practical engineering challenge: you need to build an enclosure for your dogs, using material that they can't chew through. It's going to be a lot of work to build, so you want to do it right. What material should you choose for the fencing? This project uses the scientific method to evaluate materials. Read more

Engineering Design Process
Microfluidic devices are small tools used in different fields like engineering and biomedicine. Scientists and engineers use these devices to work with very tiny amounts of fluids for various experiments. These experiments can include things like biomedical research, creating new medicines, and even applications in the car industry. In this project, you will create and test your own microfluidic device design and compare it to other designs. Read more

Scientific Method
Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Can a human hair hygrometer also detect changes in hair structure caused by chemical lightening? This project shows you how to find out. Read more

Scientific Method
It's hard to imagine a world without paper. You wouldn't have things like books, cards, comics, newspaper, construction paper, notebooks, cereal boxes, or that nice sound of shredding wrapping paper on your birthday. There was a time, though, when the only thing people had to write on were slabs of soft, squishy clay. When these slabs dried in the sun, they preserved simple ideas, but they were heavy, like carrying around a load of rocks. Not exactly easy to put in your pocket and carry around.… Read more

Scientific Method
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 strength of materials. Does spaghetti get extra strength if you bundle it together, or does strength simply increase proportionally with the number of strands? If you are interested in materials testing, get cracking!

Scientific Method
Here's a project for a budding architect or structural engineer. Can you make a strong, lightweight tower using only uncooked spaghetti and white glue? In this project, you'll learn about materials testing and apply what you learn to building and testing structures that are both strong and light. Read more

Scientific Method
Do you ever use plastic wrap to cover a container? Did you know that it is made of plastic, which significantly contributes to the amount of waste in our landfills? There are many alternatives to plastic, and one popular product is beeswax wraps. Are beeswax wraps a suitable replacement for plastic wrap? Find out in this experiment! Read more
Science Fair Project Idea
Scientific Method
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 many more. In this project, find out how gels are made and how they can be adjusted from firm to soft by changing the ingredients. Read more

Scientific Method
Through the ages, creative minds have made an amazing variety of paper toys, many of them delicate, beautiful, and inspiring. All too often, though, they do not withstand very well the wear and tear of play. This science project is your chance to fix that. You will make paper dolls with movable parts and study how the choice of materials influence the strength of the toy. Beginning with a strong design, you will finish by making a durable paper doll (or toy) with moving parts. Read more
Science Fair Project Idea
Scientific Method
Why do different types of fruits come packaged in different ways? In this project, you will experiment with different ways of packaging fruit to see if it has an effect on the freshness of the fruit. Will a different kind of packaging allow the fruit to stay fresh longer? Read more
