Middle School Science Projects (11 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.

Imagine a wonderful summer day at the beach. You play in the sand, swim in the ocean—and, of course, put a lot of sunscreen on. The sunscreen protects your skin from harmful ultraviolet (UV) radiation. Special ingredients absorb or reflect the UV rays so they do not harm your skin. Different types of sunscreen have different types of ingredients, and some of them can be harmful to the environment—especially if they get into the ocean. In this science project you will put your…

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.

During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the…

Many people routinely use fertilizer for crops, gardens, and lawns. What people don't know is that each time they apply fertilizer, the fertilizer seeps through the soil into the water table. This can eventually lead to the contamination of a local water source, like a stream, pond, lake, bay, or ocean. This is an especially big problem for agricultural practices that frequently use large amounts of fertilizer on fields that are connected by irrigation channels. The run-off of fertilizer…

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.

Chemicals from Earth's atmosphere are making their way down to the planet! Not in spaceships, but in rain. The acid rain can infiltrate ground water, lakes, and streams. How does acid rain affect aquatic ecosystems?

The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to become more acidic. What impact does that have on the marine life? In this ocean science fair project, you will demonstrate ocean acidification and investigate the effect on the shells of marine life.

You might know that lead can be toxic, and that you can get lead poisoning from eating or inhaling old paint dust. Lead is called a heavy metal, and there are other sources of heavy metals that can be toxic, too. Silver, copper, mercury, nickel, cadmium, arsenic, and chromium are all heavy metals that can be toxic in certain environments. In this experiment, find out if one common heavy metal, copper, can be toxic to an aquatic environment.

Of course it can, you say: ice is water and ice floats! And you're right. But we're talking about water in the liquid phase (the title reads better without getting overly specific). So how about it? Can liquid water float on water? Check out this project to find out.

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will…
