Sixth Grade Science Projects (415 results)

Science Buddies' sixth grade science projects are the perfect way for sixth grade students to have fun exploring science, technology, engineering, and math (STEM). Our sixth grade projects are written and tested by scientists and are specifically created for use by students in the sixth grade. 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, sixth graders 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.

Have you ever looked at sunlight through a prism? If so, you know that the prism can separate the sunlight into many different colors of light — a rainbow. Like sunlight, chemical mixtures can also be broken into their component parts. One way of doing this is a simple technique called paper chromatography. What do you think you will see if you use paper chromatography to look at the components of black ink? Is black ink just black? Find out for yourself! Read more

When you were little, did you ever make "music" in your kitchen by banging kitchen utensils on pots and pans? What if you could actually take those kitchen implements now, and play them with different sound effects? In this project, you can convert basic kitchen utensils into your own electronic drum set using the Raspberry Pi Projects Kit. Check out the video to see what this simple, but fun, project looks like: … Read more

Imagine telling your friends about your latest science project: using a battery to make a light turn on. You might get some blank stares...sounds a little boring and basic, right? Now tell them you will do it with a potato! Yes, you can actually use fruits and vegetables as part of an electric power source! Batteries power many things around you, including cell phones, wireless video game controllers, and smoke detectors. In this science project, you will learn about the basics of battery… Read more

You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if you turn them off, their magnetic properties disappear. Electromagnets are an important part of many electronic devices, like motors, loudspeakers, and hard drives. You can create an electromagnet with a simple coil of wire and a battery. In this project,… Read more

Do you know what is living in your backyard? How about at the playground, or in your compost pile? Nematodes, also called roundworms, are the most abundant animal on Earth and they might be living in any of these places. In this science project you'll isolate nematodes from several soil samples to discover the best nematode habitats. Read more

As you move up or down in altitude or elevation, the temperature and pressure will change. This is particularly striking if you live near a mountain range. During the summer, at low altitudes you may have temperatures in the 80's or 90's and still be able to see snow on mountain peaks at high altitude. You can test the effect of altitude by comparing temperature data from weather stations at high and low altitudes. You can test the effect of elevation by making your own weather balloon and… Read more

Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead compounds were also added to gasoline to prevent engine knocking, until being phased out beginning in the 1970's. Although paint and gasoline sold today no longer contain lead, soil can have contamination from older sources of lead, such as paint from old… Read more
