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.

Science Fair Project Idea
Over time, viruses evolve. Their evolution is influenced by both neutral drift, the natural mutation rate of the virus, and selective pressure from the hosts' immune systems. Scientists study a virus's genomic evolution—the changes at the nucleotide and amino acid level—to better understand how the virus is spreading and the clinical implications. You can use public databases and tools to do the same type of tracking and analysis of COVID-19 that scientists around the world do. … 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

Can you imagine a glowing loaf of bread? You might not be able to make the whole loaf glow, but you can get baker's yeast to fluoresce! The way to do this is to modify the genetic information of the yeast organism. The technology that is used to do this is called genetic engineering. With genetic engineering, you can insert a fluorescent protein gene from a jellyfish into yeast cells, so they start glowing under blue light! Do this project to see for yourself! 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

Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more

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!"

People have a variety of reasons to use heart rate monitors. For example, patients in a hospital might have stationary, bedside equipment monitor their heart rate and alert medical staff in case of an emergency. Somebody going for a run might wear a portable heart rate monitor to keep track of their workout intensity. Heart rate monitors are not all the same—their appearance and function will vary depending on the intended use. In this project you will design, build, and program your own… Read more

Have you ever been told to avoid certain foods because they contain too much fat? Almost every food we eat has some amount of fat in it; often in an invisible form so we do not even notice. However, eating healthy does not mean getting rid of all fat in your diet. On the contrary, fat is an essential nutrient for your body! Only consuming too much of certain fat types creates problems. Are you curious about how to determine the fat content of different foods? Gather some chips, chocolate, and… Read more

"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

Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more
