10 No-Prep STEM Experiments That Always Work.

Ten-minute science you can run with what's already in your kitchen drawer. Hand-picked by our Montessori educators. Ages 6–12.

It's 2:47 on a Saturday afternoon. The rain hasn't stopped. The tablet has been confiscated. The kid is on the kitchen floor saying I'm bored for the fourth time. You have ten minutes before you lose the afternoon — and you need something that doesn't require a trip to the store, a prep table, or a PhD.

This is the pack our educators pull out when that exact moment happens. Ten experiments we have each run with kids more times than we can count. Every single one works. Every single one takes ten minutes or less. Every single one uses stuff you already have.

❓ FAQ

The honest FAQ

Is this just your free blog content in a pack?
No. Three of these experiments appear on the blog in some form. Seven do not. All ten include content you can't get on the blog — the educator's note, the classroom adaptation, the what-they're-learning cheat sheet, and the video walkthroughs. If you're already an SPF regular, that's what you're paying for.
My kid is 4 (or 14). Will this work?
Probably not a perfect fit. It's built for ages 6–12. A curious 5-year-old can do about half of these with help. A 13+ kid will find them too simple unless you use the challenge extensions. If it's not right, the refund policy is real — ask and we'll send your $9 back.
I teach a class. Can I use it with all my students?
Yes, one purchase covers your classroom. We've priced this assuming teachers will. If you want multi-classroom school-wide licensing, email us — we have separate pricing for that.
What if I don't like it?
Email us within 30 days and we refund you. No form to fill out. No questions about what you didn't like (though we appreciate the feedback).
Is there an upsell after this?
Yes — and we'd rather tell you now than spring it on you. After you buy this pack, you'll see an optional offer for the STEM Flight Lab, our 4-week unit on flight (one topic, much deeper). You do not need to buy it. The pack you just bought stands alone.
