The Ultimate List of Interesting Research Topics for Kids

Inside: A list of interesting research topics for kids in elementary school or homeschool!

Teaching research skills is so important in elementary school. We can help our students navigate the “how-tos” of research. Learning how to navigate text features in nonfiction books, finding credible sources online, and taking notes are all skills we’ve mastered and can pass on to our knowledge-thirsty students.

One of the tricky things is taking the time to come up with interesting research topics for kids and coordinating research units for each topic. Our students still need some scaffolding and guidance, and there are so many things they study in school. How can we possibly decide what topics they should research and have time to put together comprehensive units?

My Black History Research Journal- the Ultimate List of Interesting Research Topics for Kids

I’ve got you covered with a list of engaging research topics for kids!

A ready-to-go research unit, that follows my 5-step research process,  is also available for many of these topics for your convenience! These unit studies will allow you to expand on content taught in class or start fresh with science and social studies research units complete with everything from unit outlines, parent letters, and internet research lessons to help students find credible sources, projects, reports, journaling pages, and more.

Students will also build their research skills during the process, so these units are a great way to make time for science and social studies with an integrated curriculum since you will still teach the necessary language arts curriculum at the same time.

Learn how to skyrocket your students’ research skills by listening to this episode of Wife Teacher Mommy: The Podcast.

What are some good research topics for kids?

From the solar system to dinosaurs, scientists & inventors, and holidays around the world, below are good research topics for kids, possible research questions for kids to answer, and other interesting research topics for kids related to the topic.

This Solar System Research Unit has students research a planet of choice (yours or theirs), create a model, and write a report. Research should be more than just taking notes and writing a report, and this unit really brings art into STEM!
