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.

"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

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

Remember going to the doctor and getting vaccine shots? It is no fun getting poked with a needle, but fortunately, a vaccine gives you protection against a serious illness for years to come. But what about the flu vaccine? How come there is a new one every year? This science fair project will show you why. Read more

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

Science Fair Project Idea
Have you ever seen a product labeled "biodegradable" or "compostable" and wondered just how well it decomposes? A lot of different products claim to be biodegradable or compostable, such as food containers, bags, packaging materials, and spoons and forks. Not only do they clearly come in different shapes and sizes, but they are made of different materials as well. Do they decompose differently, and, if so, which decomposes the fastest? In this science project, you will make your own indoor… Read more

Have you ever wondered how an AM radio station works? In this project you will learn the basics of how your favorite songs are transmitted by a radio station, by building your own simple AM radio transmitter. You will learn the basics of how a transmitter works, and how you are able to tune to your favorite station and listen to music. Read more

Science Fair Project Idea
Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In… Read more

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

Science Fair Project Idea
The iodine clock reaction is a favorite demonstration reaction in chemistry classes. Two clear liquids are mixed, resulting in another clear liquid. After a few seconds, 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 chemistry project, you will explore factors that affect the rate of the iodine clock reaction and can even record… Read more

Science Fair Project Idea
You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use Google's Science Journal app to demonstrate how the data can be picked up by a nearby smartphone. Read more
