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? What about other structural shapes (e.g., T-beams, U-beams)? In this project you can find out by setting up a test stand, putting on your safety goggles and measuring how much stress these building components can handle before they snap.

The insides of a car engine get very hot when the engine is running. Motor oil lubricates the moving parts, to keep the engine operating smoothly. What happens to motor oil as the engine temperature goes up?

Can you imagine clothing, handbags, or shoes made from seaweed or spider silk? To become more sustainable, the textile industry is looking for ways to develop more eco-friendly fabrics. Biofabrics derived from living organisms such as seaweed or bacteria have been proposed as a potential alternative to conventional fibers. In this science project, you will make several biofabrics from alginate (seaweed) and conduct tests to find out which one is most suitable as a textile replacement.

Did you know that you can make a simple hygrometer (a device for measuring the relative humidity of the air) with hair? Search online for instructions to build one. Does the type of hair used in the hygrometer affect the accuracy of the results? Do some types of hair respond faster than others? Do some types of hair give a larger (or smaller) response? You could get hair samples from classmates, or a local beauty shop. Use hair samples of equal length to construct each hygrometer. To force…

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.

Have you ever broken a candy bar in half to share with someone? Some might snap in half quite cleanly, but others might be gooey and flexible. If you stick a candy bar in the freezer, will this change how the materials break? Try this sweet project to find out!

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.

What should you NOT forget when going outside on a sunny day? To put sunscreen on! Sunscreen is important because it protects your skin from sunburn. But there are so many sunscreens to choose from: different methods of application (sprays and lotions), different Sun Protection Factors (SPFs), and different ingredients. Which one is best? In this science project, you will test the effectiveness of different sunscreens and find out how water-soluble they are.

What are the best materials to use for blocking out unwanted noise from the environment? You can build a test box (or test frame) around an audio speaker. Use a sound level meter to measure the speaker output. Use different materials to cover the walls of your test box (or frame), and see which materials do the best job at blocking the sound. For a more advanced project, perform your tests using different sound frequencies. Are some materials better at blocking certain frequencies than…

Can you catch a bubble with your hands? What if you use another material, like a piece of paper or aluminum foil? Try this science project to find out which materials can catch a bubble without popping it.
