Pick a Topic & Submit Here

The first step of your Science Fair Project is to pick a topic. Here are some tips:
  1. What are you curious about? Does water boil faster at the top of a mountain? Is there an app that tracks when I should brush my teeth? How can I build a better mousetrap?

  2. Once you've figured out your question, narrow it down. How could you create an experiment that would test your specific question? For example, you might boil water at the ocean and boil water at the top of a mountain to see if the water boils more quickly, depending on where you’re located.

  3. See if anyone else has done a similar experiment, and if they have, read about what they did and what they found. You may want to repeat the same experiment to verify the results, or you may want to create a whole new experiment.

  4. Keep it simple. Experiments do not have to be elaborate, expensive or take a lot of time. Avoid experiments that involve animal or human testing or hazardous materials.

Eligible Categories

Below are the most common categories of projects that we accept, but we will accept projects from any of the categories designated by the LA County Science Fair.

  1. Behavioral Science – study of human & animal behavior – includes psychology, sociology & more

  2. Biology – study of living things – plants & animals (consider splitting into two categories: Animal Science and Plant Science)

  3. Chemistry - study of substances - combine them, create compounds, analyze reactions and the materials involved

  4. Earth & Environmental Science – anything involving the earth – weather, climate, volcanoes, fossils, rocks & more

  5. Engineering & Electronics – Designing, creating & studying the function of machines, technology, electronics & their process. 

  6. Medicine & Health

  7. Physics – study of matter & energy including light, sound, magnetics, motion & more.

  8. Space & Astronomy – study of the universe and all its parts including stars, planets, moons, meteors & other celestial bodies
