Twelfth Grade Science Projects (158 results)

Science Buddies' twelfth grade science projects are the perfect way for twelfth grade students to have fun exploring science, technology, engineering, and math (STEM). Our twelfth grade projects are written and tested by scientists and are specifically created for use by students in the twelfth 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, twelfth 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
Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which method of timekeeping is the most accurate? Get ready to synchronize your watches! Timekeeping is the science of how to keep time with precision and accuracy. People have been finding ways of measuring time for thousands of years, usually based on the movements… Read more

Science Fair Project Idea
The first man-made satellite, the Sputnik 1, was launched in 1957. As of late 2020, more than 2,600 man-made satellites orbit Earth, with a little over 70% of them in low Earth orbit. If you would like to delve into how satellites and their sensors are configured, or into how their orbits are planned—and do not shy away from a little programming—this project is for you! With the help of FreeFlyer®—powerful software that allows you to simulate satellite orbit and… Read more

Science Fair Project Idea
Scientists recently found that some small drugs can stop infection by the deadly Ebola virus in its tracks. Lab researchers found that these drugs bind to a protein that the Ebola virus uses to enter our cells, and this is how infection is prevented. However, this also means that the bound protein no longer functions in our cells. How might these drugs accidentally disrupt important biological processes in our bodies? What other proteins might these drugs bind to? In this science project,… Read more

Science Fair Project Idea
Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use a Web-based… Read more

Science Fair Project Idea
Mechanical switches are common in many machines and robots. They can be used to detect when a button is pushed, when a door is open, or a low-speed collision when two objects bump into each other. Switches can act as "bump sensors" on a simple robot to help it detect when it hits an obstacle. The robot can use this information to navigate around obstacles and avoid getting stuck. Can you build and program a robot that can drive around your house while using bump sensors to avoid obstacles? Read more

Science Fair Project Idea
Electronic devices can be designed to detect dangerous fumes or other hazards, such as smoke or carbon monoxide. In this electronics project, you will build another potentially life-saving detector—a radon detector. Radon gas is radioactive and can pose a hazard to your health if you live in an area where it leaks from the ground. In this electronics science project, you will learn how to collect radon with an ordinary dusting cloth mounted on the intake of a fan, and then measure its… Read more

Did you know that mixtures can be unmixed? Chromatography is an analytical technique in chemistry to separate mixtures and identify each of its individual compounds. In this project, you will separate ink dyes found in different markers using a strip of paper, chalk and different liquids. By comparing different chromatography substrates and solvents, you will learn how different attractive forces between substances can affect the separation of a mixture into its individual components.

Safety Notes about Neodymium Magnets: Handle magnets carefully. Neodymium magnets (used in this science project) are strongly attracted and snap together quickly. Keep fingers and other body parts clear to avoid getting severely pinched. Keep magnets away from electronics. The strong magnetic fields of neodymium magnets can erase magnetic media like credit cards, magnetic I.D. cards, and video tapes. It can also damage electronics like TVs, VCRs, computer… Read more

Science Fair Project Idea
Can bacteria be altered to produce life-saving insulin for diabetics? Or change color to indicate the presence of a harmful toxin? Yes, it can! Using biotechnology, scientists work daily on problems like these. It starts with selecting a gene you want bacteria to produce and creating a sequence of DNA that has that gene and a promoter that will help express it at the right time and at the right levels. The next hurdle is actually getting this engineered DNA into the bacteria and… Read more

Can you imagine Valentine's Day or Halloween without chocolate? Well, if you're a chocolate lover brace yourself for the bad news. According to the United States Department of Agriculture (USDA), "Worldwide demand for cacao now exceeds production." If there isn't enough cacao, the major raw ingredient for chocolate, then the chocolate supply will dwindle. Hang on! Before you start rushing to the store to buy all the chocolate you can get your hands on, a solution is already in the works. In… Read more
