40 Unit Study Ideas to Spark Curiosity in Your Homeschool

If you’ve ever found yourself staring at a blank planner wondering what should we explore next?, this list of unit study ideas is here to help. Whether you’re a seasoned home educator or just starting out, unit studies are a brilliant way to bring together different subjects in a cohesive, interest-led way. They allow your child to dive deep into topics that matter to them—while you effortlessly weave in skills from across the curriculum.

A unit study is an educational approach that focuses on a specific topic, theme, or subject area, integrating various subjects like math, science, history, and language arts into a cohesive learning experience. Instead of teaching each subject separately, a unit study allows students to explore a topic in depth, making connections across different disciplines.

In this post, you’ll find 40 creative and flexible unit study ideas designed to spark curiosity, invite exploration, and make planning easier. These ideas aren’t tied to any specific age or Home Education Philosophy – they’re adaptable and open-ended, giving you the freedom to shape them to suit your family’s style, your child’s learning stage, and your educational goals.

And if you’re eager for even more ideas, don’t miss the free downloadable resource which includes all 40 ideas from this post, plus 40 more exclusive ideas — giving you a total of 80 unit study prompts! You’ll also receive a printable subject mapping template to help plan each unit and a blank list to record your own ideas.

How to Plan a Unit Study

There are so many exciting directions you can take when designing a unit study. You might build one around your child’s passions — their pets, a favourite book series, a place you’re visiting, or even a question they’ve asked.

A unit study can last from just a few days to several weeks or even a full term, depending on how deeply you want to dive into the topic. The beauty of this approach is its flexibility — you can go as broad or as deep as your family needs.

Take Ocean Life, for example. This unit could include:

• Science – Learn about marine ecosystems and animal adaptations.
• Geography – Explore the world’s oceans and how currents affect climate.
• English – Write underwater adventure stories or research reports.
• Maths – Graph ocean temperatures or calculate migration distances.

See the Ocean Life Subject Mapping Example below for inspiration.
