Science lesson plans by grade
Every listing on ClassCrafted carries the grade levels it was built for, so you can go straight to your year. If you teach 5th grade, for example, you'll find science experiments around matter and its interactions, ecosystems, Earth's systems, and space — alongside worksheets, lab sheets, and review games for the same standards.
Science experiments and lab activities
The science resources teachers reach for most are the ones that get students doing: structured experiments with clear hypotheses and observations, lab activities with recording sheets, and projects that stretch a concept over a week. Look for listings that spell out materials, safety notes, and the questions students answer along the way.

Science resource questions
What comes with a science lesson plan?
Each listing describes its own contents. Every resource page shows the file format — PDF, Word, PowerPoint, Excel, ZIP, Google Docs, Slides, or Sheets — plus preview images, the grade levels it covers, and reviews from teachers who bought it. You can message the seller with questions before you buy.
Are there free science resources?
Yes. Some teachers share their materials free, and you can filter any search to show only free resources. Others are paid, and each purchase pays the teacher who made it — ClassCrafted keeps a 15% platform fee and sellers keep 85%.
