Tenth Grade Science Projects (298 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.

Avoid the Shock of Shocks! Build Your Own Super-sensitive Electric Field Detector
Science Fair Project Idea
Wouldn't it be nice to avoid those nasty electric shocks you get after you have walked around on carpet and then touch a doorknob? These shocks are caused by static electricity. In this project, you will build a super-sensitive charge detector to investigate the electric fields created by static electricity. The detector can sense invisible electric fields before you touch something and get zapped, so try this project to avoid the shock of shocks! Read more

Bet You Can't Hit Me! The Science of Catapult Statistics
Science Fair Project Idea
If you have ever tried to hit a target (such as a trash can) with a wad of paper, you know that aim is everything. But it is not always easy to get it right every time! Missing is not that big a deal with a wad of paper, but what if you were in an invading army in the Middle Ages, using a catapult to hurl huge stones and knock down castle walls? For a successful invasion, it would be important to know exactly how far, and how reliably, a catapult could launch a projectile. In this project you… Read more

Build a Zippy Line-following Robot (BlueBot Project #3)
Science Fair Project Idea
How easy is it for you to walk along and follow a line that is painted on the ground? Simple, right? You might be able to follow a line without giving it much thought, but how could a robot do that? In this project, you will build your own automatic line-following robot that can race around a track that you create. This technology has plenty of real-world applications—maybe one day you could help design self-driving cars! Read more

Build an Obstacle-Avoiding Robot (BlueBot Project #4)
Science Fair Project Idea
In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

Burning Calories: How Much Energy is Stored in Different Types of Food?
Science Fair Project Idea
Have you ever wondered how nutritionists know how many Calories a certain food contains? In this project you will learn a method for measuring how many Calories (how much chemical energy) is available in different types of food. You will build your own calorimeter to capture the energy released by burning a small food item, like a nut or a piece of popcorn. This project gives a new meaning to the phrase "burning calories!"

Chemistry of Ice-Cream Making: Lowering the Freezing Point of Water
Science Fair Project Idea
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

Death Rays: What Duration of Ultraviolet Exposure Kills Bacteria?
Science Fair Project Idea
Ultraviolet light can damage DNA molecules. If a cell's DNA repair mechanisms can't keep up with the damage, mutations are the result. As harmful mutations accumulate, the cell eventually dies. How much ultraviolet light is too much for a bacterial cell? Read more

Discover Chlorophyll Variety in Different Plants Using Paper Chromatography
Science Fair Project Idea
Do you like to analyze stuff and finding out what it is made of? An analytical chemistry method, called chromatography, allows you to separate mixtures of compounds and to identify each individual compound within the mixture. Chromatography is used by many scientists, for example food scientists, forensic scientists, or organic scientists to analyze all kinds of mixtures such as food, blood, or medicine. In this project, you will be using paper chromatography to analyze the pigments from… Read more

Do Oranges Lose or Gain Vitamin C After Being Picked?
Science Fair Project Idea
Are oranges highest in vitamin C when they are fresh from the tree (or, in a pinch, the grocery shelf)? Does the amount of vitamin C in an orange change over time, after it has been picked? In this science project, you will find answers to these questions by measuring the amount of vitamin C in a solution using an iodine titration method. Read more
