Materials science is a fascinating area of research that is often at the cutting edge of science and engineering. It involves both developing new materials and improving on existing ones, and has important applications both for improving daily life and for advancing other fields of research. You can try your hand at making and testing all kinds of substances from plastic to slime.

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.

You have probably seen it on You Tube™ — the exploding Coke® and Mentos®
experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller
eruption? In this science project, you will see if using crushed
Mentos candies, instead of whole Mentos candies, will affect the reaction.

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.

Have you ever wondered why some things disappear when they are put in water but other things do not? For example, you may have seen that salt disappears, or dissolves, when it is mixed in a glass of water. But when you throw a rock in a stream it will not usually dissolve, and instead it will just sink to the bottom. And then there are some things that do not act like the salt or the rock. These are called colloids. If you have made Oobleck out of cornstarch and water, then you have seen…

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?

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.

Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far?
The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse…

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.
