Fifth Grade, Materials Science Science Projects (24 results)
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.

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!

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…

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 show you how to measure the porosity of sand: how much air space there is in between the sand grains. Maybe you can use your knowledge from this project to help you make bigger and better projects with sand.

Have you ever seen an arch structure in a building, such as over a doorway or surrounding large windows? Arches have been used for structural engineering since ancient times. This experiment tests the strength of a naturally occurring arch shape: the shell of an egg. How much mass do you think an eggshell can support?

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.

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.

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.

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.
