Using the Scientific Method with Kids
The scientific method helps kids think like scientists:
- Ask a Question – What do you want to know?
- Make a Hypothesis – What do you think will happen?
- Do the Experiment – Try it out!
- Observe & Record – What did you see or measure?
- Analyze & Conclude – What did you learn?
Whether you’re casually chatting with preschoolers or guiding older kids with formal journal pages, this process builds problem-solving and critical thinking skills.
🔎 This is a great opportunity to explore the scientific method, learn how to write a hypothesis, and choose variables!
Make It a Science Project
Turn your favorite kitchen science experiment into a full-blown science project!
- Test different variables (e.g., types of milk in butter-making)
- Try multiple trials to compare results
- Use the scientific method to structure your project
- Create a display board with your observations
Great for homeschool science fairs, classroom projects, or just extra learning at home.

Love the cookie cutter idea. My little preschooler loves this mini science experiment: milk in bowl, food coloring drops and swirl with toothpick. Entertains for a good 20-30 minutes every time.
it’s never too late to share this on #kidsinthekitchen 🙂 http://lookwhatmomfound.com/2014/05/peanut-butter-oatmeal-power-bites-kidsinthekitchen.html
These are so cute and fun! Science experiments are always a hit with the kids. Thank you for sharing!
I am always intimidated by doing science experiments with my boys. I know they’d love them… but science was not my thing. So I shy away from them. These look so easy though, we may have to give ’em a try! Thanks for sharing on Makeovers & Motherhood’s Welcome Party Wednesday Link-Up! I am featuring you this week!
It is great when we can use items we already have at home to help our children have fun learning! These are wonderful ideas that are easy to prepare. And I love that you contained each on a separate tray, should make clean-up a bit easier. Thanks for sharing at the Thoughtful Spot Weekly Blog Hop!
Everyone loves what you guys are up too. This kind of clever work and exposure!
Keep up the terrific works guys I’ve added you
guys to my blogroll.
Making sugar crystals in the kitchen is another great one! We can’t wait to do some edible engineering ourselves!
