Bacterial Resistant Materials and the Best Disinfectant

Science Fair Project Idea

Scientific Method

If you'd rate yourself high on the bacteriophobia scale, just keep on scrolling down to the next project. Bacteria are all around us, and normally our body's defenses keep us blissfully unaware of them. If you don't mind finding out where they're lurking in your house, then you might find this project interesting. Read more

Have you ever seen an arch structure in a building, such as over a doorway or surrounding large windows? Arches have been used in structural engineering since ancient times. In this activity you will test the strength of a naturally occurring arch shape: the shell of an egg. So grab some eggs and put them to good engineering use in trying to answer the following question: Just how much mass can an eggshell can support? 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

Maybe you have grown vegetables or flowers, but have you ever grown the flowerpot? Yes, you read that right! In this activity, you will use mushroom roots to grow a biodegradable material that can be molded into a product of your liking, like a flowerpot! Growing a set of bowls, a lampshade, or a pot is easier than you might think. Once you try it out, you just might feel inspired to replace some of your plastic objects with ecological counterparts that you created from mushroom roots! 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

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

Turning Mushrooms into Environmentally Friendly Packaging

Science Fair Project Idea

Scientific Method

Have you ever questioned the packaging of an item in a plastic container, secured in a plastic mold, that also slides into a plastic box, or a small item packed in twenty times its volume of polystyrene noodles to keep it from breaking? In this project, you will explore if mycelium composite material, an eco-friendly material obtained from organic waste and mushroom roots, can serve as a viable eco-friendly packaging alternative. Packaging material made of foams and plastics (Figures 1 and 2)… Read more

How does light interact with matter? In this fun hands-on lesson, your students explore how different materials transmit, absorb and/or reflect light. They create their own experiments to demonstrate these phenomena and use a phones' built-in light sensor and a sensor app to add quantitative data to their arguments. Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
