Industry, Innovation and Infrastructure, Seventh Grade, Materials Science Science Projects (14 results)

The United Nations Sustainable Development Goals (UNSDGs) are a blueprint to achieve a better and more sustainable future for all.
These projects explore topics key to Industry, Innovation and Infrastructure: Build resilient infrastructure, promote sustainable industrialization and foster innovation.

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.

Simulate Microchip Clean Room Contamination with Crayon Leaf Rubbings

Science Fair Project Idea

Scientific Method

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process. Read more

The Surprising Strength of Eggshells

Science Fair Project Idea

Scientific Method

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

Strength in Numbers?

Science Fair Project Idea

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!

Build Your Own Microfluidic Device

Science Fair Project Idea

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

Which Metal Is the Most Resistant to Corrosion?

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

The Leaning Tower of Pasta

Science Fair Project Idea

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

It's Hard Work to Work Harden! Learn How to Make Metals Stronger

Science Fair Project Idea

Scientific Method

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

Measuring Density and Porosity of Sand

Science Fair Project Idea

Scientific Method

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

Stressed Out? Take a Break with this Project!

Science Fair Project Idea

Scientific Method

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

The Viscosity of Motor Oil

Science Fair Project Idea

Scientific Method

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? Read more
