What should you include in your high school science project?

Science teachers hold students ages 14-18 to a much higher standard when grading science projects. High schoolers must demonstrate a solid understanding of the scientific method and reflect current guidelines in the Science, Technology, Engineering, and Mathematics (STEM) industry. Students’ science projects must also demonstrate their curiosity and eagerness to explore new and complicated scientific concepts.

Structure your science project neatly in sections, and make sure you include all necessary components: Purpose, Background Information, Scientific Question, Hypothesis, Materials, Procedures, Results, Conclusion, and Works Cited/Bibliography. When editing your science project, some questions to ask yourself are:

  • Are my steps clear enough for someone to easily replicate my results?
  • Do I have tables and graphs to illustrate the collected data? Are they easy to read?
  • How original is my idea compared to other high school science projects?
  • How can I present my science project in a clear way to ensure my audience understands the complicated scientific concepts?
Science Project Ideas for Each Subject

In high school, students typically take Biology, Chemistry, and Physics chronologically from 9th to 11th grade. 12th graders can choose which science subject they performed best in and take an AP science class in that subject for a challenge and to college credit. Depending on their school’s science class offerings, high school seniors can also take more focused science classes such as AP Environmental Science, AP Psychology, AP Human Geography, or AP Computer Science. Learn more about the differences between each subject.

With so many intriguing science project ideas for high school students, choosing a project that’s best for you can be difficult. When reading through this list, consider which ideas strike your interest. Do they relate to something your teacher mentioned in class? Is it a science project you’ve always been curious about? Would you want to study this topic as your college major? Will this science project be helpful in your portfolio when applying for your dream university?

When you find a science project idea that appeals to you, the best way to approach the topic is to do background research. Look up some keywords from the description in research journal databases, such as The Concord Review and Journal of High School Science. These 12 research journals are easier to read and more suitable for high schoolers because the papers are all written by other high school students.

Biology Science Projects

  • Explore gene editing and its possibilities by creating genetically modified organisms or treating genetic disorders.
  • Discover why people get seasonal allergies and which biological differences make some people more prone to allergic reactions than others.
  • Research an invasive species that was recently introduced in your community, and predict its impact on native species.

If you’re curious to learn more about biology, consider taking an AP Biology class at your high school. Or, if you’re just getting started, check out an online class on the foundations of biology.

Chemistry Science Projects

  • Test how effective Advil (ibuprofen) is compared to Tylenol (acetaminophen) when dealing with different symptoms and illnesses.
  • Examine the chemical anatomy of different artificial food dyes or other additives, and compare their effects on our health.
  • Develop a skincare product that’s safe to use.

Physics Science Projects

  • Explore the popular yet controversial topic of how one electron can be in two places at once.
  • Determine the differences between the two atomic bombs the U.S. used in World War 2.
  • Uncover the differences in safety features between a gas engine car and an electric car when rapidly decelerating from a high speed.

Environmental Science Projects

  • Compare the water pollution levels in your town and a neighboring town to determine what factors might be causing higher pollution levels. Propose a social change initiative to lower water pollution.
  • Conduct a study on your school’s recycling habits. How can the current system be made more efficient? How much recycling ends up as unusable waste in landfills?
  • Investigate solutions to cleaning up oil spills. What is the most effective method?

In most cases, studying Environmental Science requires a solid understanding of Biology, since these subjects overlap. If you’re interested in both subjects, you might want to consider studying them in college. Before then, it’s essential to understand the differences between Environmental Science and Biology; so, choose the right AP course and earn college credit toward your future major.

Psychology Science Projects

  • Compare and contrast the effectiveness of medicine versus hallucinogenic plants for different illnesses. Why might some people prefer alternative medicine over traditional medicine?
  • Dive into how cultural or socio-economic factors may contribute to someone’s belief in conspiracy theories and political extremism on social media.
  • Research the effects of college admissions on self-esteem and long-term life satisfaction.

Presenting your Science Project in a High School Classroom

People tend to think that science projects are about writing science reports and long research papers. However, there are more engaging ways to showcase your scientific discoveries and have fun along the way!

Write a Blog
High school students can exercise their creative muscles by starting a science blog. Students can research current events in science and write posts about recent scientific developments in the STEM industry. Not sure how to get started? Here are some tips on how to create a blog.

Make a Board Game
Another fun idea to present a science project is to make a board game. As players progress across the board, they can learn about your research questions, hypothesis, variables, and what you discovered in your science experiment.

Add Kahoot to Your Slides
If part of your assignment is to make PowerPoint slides, make your presentation slides more interactive and engaging by adding a game of Kahoot. Kahoot is a website that lets you make a fun quiz to share with your classmates. You can add the game to the end of your presentation to quiz them on what they learned from your science project. Prepare a small prize for whoever gets the most correct answers!

Make a Model for a Live Demonstration
Consider whether or not your experiment can be replicated through a model in time, which is by far the best way to grab your audience’s attention. Even if your whole experiment can’t be built into a model, make part of it to help your classmates understand a difficult scientific concept.

How to Write a Scientific Research Paper
