We go through a lot of baking soda and vinegar in my house. We’re not cooking with it. We’re not cleaning with it. We’re mixing “potions” with it, erupting volcanoes, mixing it with food coloring and painting with it. Splashing salt on top to see what happens. Raiding the recycling bin and building courses for the bubbly liquid to travel down. (I highly recommend building such courses in a bathtub or on an outside deck!)
Although I’ve been an educator both in schools and the Museum for nearly 20 years, I’ve received some great insights into the way kids learn about the world observing my own kids try to figure out “what happens if” and “how does this work.”The author's son in a previous winter when snow was abundant!
This past weekend, my 9-year-old son was lamenting the pitiful ½ inch of snow on the small hill he likes to sled on in the yard. “That’s a problem,” I said. “Can you think of a solution?” After trying to relocate snow from other parts of the yard to no avail, he asked for a bucket. His solution: to pour bucket-loads of water down a path on the hill. How long will this take to freeze? How many layers of ice do I need to put on the hill to make it thick enough to hold the weight of me and my sled without cracking? Does the water freeze faster if I put cold water in my bucket?
My son was playing, getting messy and having fun, but most of all he was determined to have a place to sled by the end of the day (which was how long it took for the multiple layers of ice to freeze). Did he realize that he was conducting experiments? Forming hypotheses? Using scientific reasoning? No, but that’s okay.
Here at the Museum, we may not have the icy hill in the backyard, but we know we’ve done our job when we observe kids (and adults) engaged in asking questions, experimenting, or creating something new together. Are you looking for some “what-happens-if” fun during the cold winter months? We’d love to have you visit and experiment with us.
And check out these websites for some science inspiration you can try at home – recommended by Museum colleagues through the Association of Science and Technology Centers:
“The SciGirls website, http://pbskids.org/scigirls/, is awesome! It’s great for girls and boys.”
“www.edheads.com is a great website that has some really fun kid-friendly interactives with accompanying teacher guide (including virtual surgeries, crime scene investigations and nanoparticle development.”
“Carnegie Science Center has a website as part of our girls program at www.braincake.org.”
