With thousands of possible projects, it can be difficult to narrow down something that’s a good fit for every student. Try these tips to help them find the right science fair project ideas.

Match Your Project to Your Interests

This seems obvious, but it’s really helpful for kids who feel overwhelmed by all the choices. It’s also a good way to get reluctant learners more excited about science fair projects. Encourage students to think about what they love to do in their spare time. How can they turn that into a project?For instance, kids who love sports might explore the most effective stretches for warming up, or methods for throwing a football farther and more accurately. Music lovers can learn how sound waves work, or discover the link between music and emotions. It’s all about starting with something you love.

Challenge Yourself, But Keep It Realistic

Science fair projects need to be something kids can complete by themselves or with adults in support roles only. If a student picks something that’s way beyond their skill level, chances are the parents will wind up doing most of it. That being said, the point of the project is to learn and grow. Aim to learn something new, whether it’s knowledge or skills, by setting measurable goals.

If You Want To Win, Be Innovative
For science fair contests with prizes, the more creative you can be, the better. Projects that address real-world problems with new and interesting solutions often catch the judges’ eye. Be sure to be thorough in your research, and be ready to answer questions about your methods and results. Scientists love asking questions!
