high school science projects are the perfect way for
high school students to have fun exploring science, technology, engineering, and math (STEM). Our
high school projects are written and tested by scientists and are specifically created for use by students in the
high school grades. 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,
high schoolers 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.
Space exploration, living, and working in space exposes space travelers and their equipment to radiation not present on Earth. The study of how we can protect ourselves and our equipment is an essential part of space exploration. Although you will not be able to test at levels equivalent to what you might encounter in space, you can test with lower and safer levels of radiation in the lab or at your home.
There are many types of radiation. This project concentrates on ionizing radiation, or…
Have you ever looked at two girls and thought they looked so similar that they must be sisters? What about a father and his son — have you ever seen a boy who looked just like how his father did when he was younger? We can often tell that two people are related because they appear to have several similar physical traits. This is because children receive half of their DNA — their genetic blueprints — from each parent. What about fingerprints — are they an inherited trait?…
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…
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?
You know that sugar makes food sweet, but did you know that there are different kinds of sugar? Sucrose is the granulated sugar that you usually use for baking. Another kind of sugar, which is found in honey and in many fruits, is glucose. In this science project, you will measure the concentration of glucose in a variety of foods. You will use special test strips that change color in response to glucose to measure the glucose concentration in different foods.
Have you ever wondered how your cell phone or laptop keeps running once you unplug it? Sure, it is the battery that makes your portable electronics work, but how exactly does a battery do that, and from where does the electricity come? Generally, in a battery chemical energy is converted into electrical energy. In fact, many different types of batteries exist that are all based on a different set of chemical reactions. In this science project, you will explore a special battery variant called…
Instant cold packs are popular with coaches and parents for treating minor bumps and bruises. The instant cold packs are not pre-cooled—you just squeeze the cold pack and its starts to get cold. So how does it work? In this chemistry science fair project, you will investigate the chemical reaction that occurs in instant cold packs.
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!
One strategy you may have heard suggested for dealing with the COVID-19 epidemic is to let nature take its course and let COVID-19 infect enough of the population for us to reach the herd immunity threshold. Does this make sense as a public health strategy? You can explore this question scientifically using SimPandemic, a free online tool for modeling infectious disease outbreaks.
Before you begin, you will need to know a bit about herd immunity. Herd immunity, sometimes called community…
When you go to the supermarket, how do you pick out ripe fruits and vegetables? You might look at their size or color, or feel them for firmness. That might be easy to do when you pick out a half dozen apples, but imagine if you had to examine thousands of apples growing in a field, or strawberries coming down a conveyor belt getting ready for packaging. Suddenly, it is a lot harder to do yourself! What if a machine could pick and sort the produce for you? In this project, you will address part…
