Teaching the Scientific Method to Preschoolers

Yes, I love science.  I admit it.  If there were enough hours in the day, it might be fun to take an online class or two in science. I love teaching my son neat things about it, too.  Science can be so much fun for preschoolers and they never know they are learning, but you are building a great foundation for future understanding of basic terms.  Like the scientific method.
To demonstrate the scientific method we had a liquid race.

                         3-2-10 001   
I grabbed an empty cookie tray (this tray just might happen to be from Oreo’s  :-P) and some liquids of different viscosity (thickness).  I propped up one end of the cookie tray and we poured the different liquids in the lanes.

                    3-2-10 003
I asked as we poured which one my son thought was going to win the race.  He told me the red one was going to win.  When I asked him why, he told me that red was one of his favorite colors and that is why. 

     3-2-10 010   3-2-10 013
So we felt each liquid with our fingers.  We compared the textures (stickiness) and thickness.  We talked about if really thick and sticky syrup would go fast or slow.  Then we talked about the differences between the Kool Aid, the syrup, and the barbecue sauce.
My son then decided that the Kool Aid would win.  When asked why, he told me that it was runnier and more like water.  Yipee!

                  3-2-10 004
So we did the race.  He was so excited to see the red win and be right.  I was excited to be there as he learned the scientific method, whether he knew it or not.  :-)  Try it.
Are you a science geek like me?  Or do you loathe it?

  1. I love it! Another great one is to add baking soda and vinegar to half a glass of water. Then add 5 raisins 1 at a time. The raisins will float to the top when enough Carbon Dioxide bubbles collect on them. A great lesson on buoyancy.

  2. I love this idea! I will have to try this with my girlie. I like your new site, grabbed your button!

  3. that's a GREAT lesson! What an easy *free* way to experiment with liquids too. I'm not sure I would have thought of using a cookie tray - but if there are ever Oreos in our house, there will SOON be an empty cookie tray for sure!! (too soon, oh too soon)

  4. LOVE LOVE LOVE this one! Now to eat a lot of cookies to get an empty cookies tray.
    Link this one up to my science sunday post this Sunday, it's so cool!
    And obviously, I'm a science geek too.......

  5. Great! I have always enjoyed science. =)

  6. wow this is an awesome idea one that I had never heard of before good for you

  7. Very neat idea! I love science. I taught 8th grade sciene/social studies one year and it was probably my most fun year of teaching.

  8. Love it! That is the experiment, not Science so much, which is why I love ideas like these to help me teach it to my daughter!

  9. You are so thoughtful and creative when it comes to your kid's learning. Are you planning on homeschooling? Just curious.

    BTW, LOVIN the new blog design. Even when I stop by here on my Blackberry, I can see the full design! So cool!

  10. I recognize that bbq sauce - K.C. Masterpiece!!! Love it!!

  11. Fun idea - and this gives me a good excuse to go buy Oreo's, right? ;)

  12. This is a great idea... thanks so much for sharing!

  13. Yay for science and preschoolers! My friend and I teach science twice a month at our church's nursery school. We have monthly themes (colors, health, our body, plants, heat/cold, magnets, etc) and do two different lessons on each. It is so much fun and a great way to enforce early that science is fun before they get to school and (hopefully not, but too often) think that it's boring. Fun experiment!

  14. Found your blog via teach preschool (Deborah), I love your blog, every children can do that. My students love to see the photos of the experiments :)

  15. What a great reason for me to indulge in some Oreos. That sounds like fun and your son is a smart little "cookie".

  16. Cool! Great project! Check out my website for more easy science for kids.

  17. What a great idea!! You are so brilliant! My 6yo loves science, and so do I, but I'm not great at ways to teach kids.
