Middle School Science Projects (632 results)

Science Buddies' middle school science projects are the perfect way for middle school students to have fun exploring science, technology, engineering, and math (STEM). Our middle school projects are written and tested by scientists and are specifically created for use by students in the middle school grades. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, middle schoolers can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Mowing the lawn is hard work, especially on a warm day. Not only do you have to mow the grass, but you also have to dispose of the clippings. Some people add the clippings to a compost pile in their yard, which is a great idea. But did you know that some grasses can be used as a source of energy? In this energy science fair project, you will learn more about a type of energy called biomass energy. You will grow different kinds of grasses and see which type of grass gives you the most biomass,… Read more

Imagine how cool it would be to build a robot hand that could grasp a ball or pick up a toy. In this robotics engineering project, you will learn how to use drinking straws, sewing thread, and a little glue to make a remarkably lifelike and useful robot hand. What will you design your robot hand to do? Pick up a can? Move around a ping pong ball? It is up to you! With these starting instructions, you can design any type of hand. You will simulate human finger anatomy as the basis for a… Read more

Close your eyes for a moment and think about your favorite cake, pasta, and crusty bread. OK, you can open your eyes now, and please do not drool on your computer! What was the cake you pictured like? Was it light and fluffy? Did you imagine pasta with a silky, smooth texture? Was the bread you pictured wonderfully chewy? Did it give your jaws a workout? In this science fair project, you will explore an amazing substance in these foods, called gluten, and discover why these foods, all made from… Read more

Did you know that your guitar has a secret? Yes, that's right—hidden along each string are special places where you can play harmonics and make your guitar sound like a bell! In this music science fair project, you'll find out where the main harmonics are located on a guitar, and then see how those locations are related to the length of the strings. So get out your guitar—it's time to ring in a science fair project! Read more

You are looking under your bed for that video game you want to play, when you come across a real treasure—an open bag of potato chips that you forgot about! A crispy and salty potato chip is a tasty treat. But wait! This potato chip is not crisp and does not taste as great as it should. What happened? The chips have gone rancid! In this cooking and food science fair project, you will look into what factors turned your chips rancid. Read more

Global warming is how scientists describe the gradual warming of our global climate. Scientists think that the trend towards global warming can be attributed to the build up of greenhouse gases in the earth's atmosphere from industrialization. Another problem is deforestation, as we remove plants and trees from the environment to meet a high demand for lumber or by clear cutting fields for farming and urbanization. By removing trees from the earth's environment, are we changing how greenhouse… Read more

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity). In this project, you will construct simple devices that hold several germinating seeds, which allow you to watch how growing rootlets respond as you rotate the devices, effectively altering… Read more
