Seventh Grade Materials Science Science Projects (16 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 with our collection of materials science projects.

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? Read more

It's easy to forget that metals are everywhere and in nearly everything. They are a part of our lives in so many ways that we hardly notice them. But just stop and think about it. We use metal spoons to eat and cook our food. Cars, bikes, and planes are composed of metals. Metals are in our furniture and part of your school supplies. Some people even have metal in the dental work in their mouths. Their strength and dependence is obviously very important. But what are metals? In this science… Read more

Does adhesive tape hang tight at different temperatures? Measure the adhesive strength of tape at both low and high temperatures. To raise the temperature, we suggest using a blow dryer at both low and high heat settings. To lower the temperature, use an ice pack (try to keep condensation from forming on the tape and confounding the results). For even lower temperatures you could try "dry ice" (frozen carbon dioxide), if available. (Wear heavy gloves when handling dry ice, because it can… Read more

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. Read more

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!

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. Read more

Do you ever go camping with your family and roast hot dogs and marshmallows over a campfire? If you want your campfire to burn long into the evening, what is the best wood to use? Do research on the necessary conditions/materials to sustain a fire and on the properties of different types of wood. Which properties do you think will be most important for determining how fast the wood burns? For example, how do you think density would be related to burning rate? Why? Measure the density and… Read more
