Science Buddies' 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.

Build a Paper Roller Coaster Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 878 reviews Have you ever ridden a roller coaster? Have you ever wanted to design your own? There are plenty of expensive toys and even video games that will let you build your own coasters—but in this project you'll make one out of paper and tape, and learn about roller coaster physics along the way!

Make an Alka-Seltzer Powered Lava Lamp Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 432 reviews Have you ever seen a lava lamp? They were the height of 1960's "groovy" room decorations. A few minutes after turning it on, a lava lamp has blobs of colored liquid floating towards the top of the lamp and then drifting back down. Making an actual lava lamp that you plug in would require some effort and unusual supplies, but you can create a non-electric version in just a few minutes with the help of the fizzing power of Alka-Seltzer. In this activity you can find out how to make your own… Read more
Build a Pizza Box Solar Oven Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 500 reviews Have you ever cooked something outside, like for a BBQ or while camping? It can be a lot of fun to be outdoors and enjoy eating the fruits — or burgers — of your cooking labors. Did you know that you can directly use solar power to cook food? This can be done using a solar oven, which is a low-cost, ecologically-friendly technology that seems to have everything going for it. In this science activity, you will build your very own simple solar oven out of a pizza box to gather the… Read more
Featured Make String from Algae Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 54 reviews Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more
How Much Weight Can Aluminum Foil Boats Float? Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 131 reviews Have you ever wondered how a ship made of steel can float? If you drop a steel bolt in a bucket of water, the bolt quickly sinks to the bottom. Then how can a steel ship float? And better yet, how can a steel ship carry a heavy load without sinking? It has to do with the density, or the mass per volume, of the ship (and its cargo) compared to the density of water. In this science activity, you will make little "boats" out of aluminum foil to explore how their size affects how much weight… Read more
Design and Launch Bottle Rockets Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 46 reviews Soda bottle rockets are a safe and fun way to get into rocketry. If you want to discover what makes rockets fly, this is an activity for you. You can even add different features, like fins, a nose cone, and a parachute to find out how these alter the flight! Try it out! Read more
Build a Mini Trebuchet Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 145 reviews You probably know what a catapult is. In the Middle Ages armies would use them to hurl stones at castle walls. But did you know about an even bigger type of medieval siege weapon called a trebuchet? Try this project to build a miniature version! Read more
Erupting Diet co*ke® with Mentos® Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 94 reviews Have you ever seen the Diet co*ke® and Mentos® experiment, which is all over the Internet, and wondered what makes the reaction work? You might think that there is some ingredient in a Mentos candy causing a chemical reaction with the soda, like the way baking soda reacts with vinegar. But the amazing eruption that takes place when Mentos are dropped into Diet co*ke is not a chemical reaction at all! Instead it is a physical reaction. That means that all of the pieces of the reaction… Read more
Do-It-Yourself DNA Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 69 reviews Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? All living organisms have DNA. DNA, which is short for deoxyribonucleic acid, is the blueprint for almost everything that happens inside the cells of an organism — overall, it tells the organism how to develop and function. DNA is so important that it can be found in nearly every cell of a living organism. In this activity, you will make your own DNA extraction kit from household… Read more
How Big Are the Planets in Our Solar System? Log in to add favorite More Menu
STEM Activity 1 2 3 4 5 44 reviews Did you know that there are more planets than stars in our galaxy? All of these planets circle around a star, but only eight of them—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune—circle around the Sun—the star in our solar system. This activity explores the relative size of these eight planets. Is one bigger than the others, or are they all about the same size? Read more

STEM Activity 1 2 3 4 5 82 reviews Have you ever been fascinated by things that glow in the dark? It can be a lot of fun to play with bracelets, wands, and other toys that are glow-in-the-dark, like some stickers and creepy, crawly, plastic insects! Have you ever wanted to make something at home that glows? It turns out that it is not that hard to do — all you need is tonic water and a black light! Some common household chemicals can also affect this beverage's glow. In this science activity, you will make tonic water glow… Read more
