Tenth Grade Science Projects (413 results)

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

Let us help you find a science project that fits your interests, with our Topic Selection Wizard.

Scientific Method
The iodine clock reaction is a favorite demonstration reaction in chemistry classes that usually requires toxic or hazardous chemicals. During the reaction, two clear liquids are mixed, resulting in another clear liquid. After some time, the solution suddenly turns dark blue. The reaction is called a clock reaction because the amount of time that elapses before the solution turns blue depends on the concentrations of the starting chemicals. In this green chemistry project, you will use a… Read more

Remembering to take medicine at the right time can be hard, especially if you need to take multiple medications at different times of day. It might not be a big deal if you forget to take your daily multivitamin, but for some people, forgetting to take medication at the right time can be dangerous. What if you had a device that could not only set off an alarm at the right time, but also automatically dispense the right pills for you? In this project, you will build an automatic medicine… Read more

Can AI understand human language? In the future, AI could aid in emergency interpretive service in the hospital when translators aren't available. But can current AI algorithms understand non-verbal languages like sign language? In this science project, you will test whether AI can learn sign language gestures or phrases to see if it can be used for interpretation. Read more

Have you ever made your own ice cream? If you have, you probably know that you need to get the ice cream mixture really cold to freeze it quickly. Ice cubes alone will not do the job, but if you add chemicals, such as salt or sugar, to the ice cubes that surround the ice cream container, the mixture gets cold enough to freeze. Why does that work? How does adding salt or sugar affect the freezing point of water? Find out with this ice-cold science project and use your results to make your own… Read more

In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics… Read more

How can you get as much power as possible out of a solar panel, even in the morning or evening when the sun is low in the sky? With a solar tracker system! While many solar panels are fixed in place on rooftops or large ground-mounted poles, a solar tracker system is motorized and lets the solar panels track the sun through the sky during the day. Are these systems worth the added complexity? How much more power do they produce? Try this project and find out!  Read more

Have you ever walked next to your favorite ocean, lake, or creek and seen plastic waste everywhere? Have you ever thought about how much plastic breaks down into microplastics and pollutes waterways? Scientists are coming up with new ways to remove these microplastics from our waterways, and now you can test them out for yourself at home.  Read more

The makers of sports drinks spend tens to hundreds of millions of dollars advertising their products each year. Among the benefits often featured in these ads are the beverages' high level of electrolytes, which your body loses as you sweat. In this science project, you will compare the amount of electrolytes in a sports drink with those in orange juice to find out which has more electrolytes to replenish the ones you lose as you work out or play sports. When you are finished, you might even… Read more

How do self-driving cars stay on the road? How do vehicles with autonomous or driver-assist features automatically brake, steer around obstacles, or perform tasks like adaptive cruise control? Experiment with these behaviors and more in this science project as you build and program your own autonomous Arduino robot. Read more

When you have your X-rays taken at the dentist's or doctor's office, do you ever wonder how the X-ray machine works? Or better yet, how you could make one yourself to use for experiments? This how-to guide provides detailed instructions for high school students and adult do-it-yourself (DIY) enthusiasts to construct and use a homemade X-ray machine safely. Read more

You may have seen police investigators on TV spraying a crime scene with a liquid that glows blue if there is any blood present. Luminol is the chemical which causes the glowing. In this chemistry science fair project, you will investigate what factors make this interesting molecule "light up." Read more

Have you ever wondered why some foods taste really sour? Vinegar is one example that you might know from salad dressings or pickles. They taste pretty sour, right? There are many different types of vinegar that you can buy to use around the kitchen for cooking and pickling. The chemical compound that gives vinegar its tart taste and pungent smell is acetic acid. Do you think all the different vinegars contain the same amount of acetic acid? Are there some that are more sour than others? How… Read more
