🎃 This is one of our Halloween crafts, back in the spotlight from Friday, 1 October 2027 — but you can make it any time you like.
← All projectsPumpkin Seed Scientists
Professor O will help you learn: Scooping out a pumpkin becomes a science lesson: guess how many seeds are inside, count them in tens, test which ones sink or float, and save some to grow next spring. It covers estimating, counting and how plants make seeds.
⚠️ An adult must cut the lid off the pumpkin with a sharp knife and handle the hot oven and baking tray. Let roasted seeds cool fully before eating. Pumpkin seeds can be a choking hazard for young children, so supervise snacking.
Play through the project step by step, with narration read aloud.
