Suds to Duds
We talked about the elements calcium, and magnesium. We formed a hypothesis on how these minerals would affect water. They started with a cup of water. We then added liquid dishwashing soap, and then told the kids to take their straw and blow! The soapy water bubbled up pretty well, with bubbles spilling generously over the cup. This was an example of soft water.
We then added two different laundry detergent boosters to see what happened to the water. The kids saw that the water bubbled even more with the boosters added! Then the kids had table salt added to their water, and then they blew once again. This time, there weren't many bubbles at all compared to before! We created very hard water.
The next experiment we did was to demonstrate how electrons can "jump"! We gave each kid a blown up balloon, and some tissue paper. We then asked them to tear the tissue paper into small pieces. Then they were told to rub the balloon as fast as they could, across their hair to create some static electricity. Once they charged it up, they took the balloon and placed it a few inches above the tissue paper. They watched the tissue paper "jump" onto the balloon! Then we had them rub the balloon with some anti-static dryer sheets. They tried a second time to pick up the tissue pieces but this time they didn't "jump"!
Feel the Force
Jokes are fun, especially when they are really experiments in the making! Next we had the kids all go around the corner, and then one at a time they were told to try and get the two giant magnets to touch, lining up the ends exactly. They were unable to do it, (I purposely had the ends set to opposite polarity). Then the last child who came through figured out that they could flip the magnets, so they would stop repelling each other!
Get a Half-Life
To help the kids understand the concept of radioactive elements, we did an edible experiment! The kids took 32 pieces of cereal to put in their cup, and then we had them eat 1/2 of them, continuing to divide them in half, at timed intervals. Once they had eaten all the cereal, we explained how that related to the half-life of radioactive elements as they break down.
If you would like explanations or step by step instructions, to replicate the above experiments; you can purchase the book Fizz, Bubble & Flash. It's a super book with easy explanations, and lots of wonderful analogies to explain things in child friendly fashion!
Fizzy Frenzy, Hocus Pocus, Feverish Fizz, Glow-In-The-Dark
I had a perfect kit that we broke out for this week's Wonderful Wednesday! You can get it from Amazon for less than $20, and you can replicate many of the experiments a number of times! One word of caution though - I did away with all the "hocus pocus" and reference to magic - eliminating the sorcery feel that the kit intended to have (I guess it's capitalizing on Harry Potter). I just removed the contents, and then used the kit as I saw fit for the experiments I wanted to use. It is simple and has easy instructions, with everything you would need for all of the experiments!
We moved on to our trail mix for snack time, which went with our dress up theme for this week's geography - hiking those trails!
Dress-Up and Snack Time
One of the great joys of doing school in Community with friends, is the way the children develop their friendships through the process. It was so much fun to watch them play, after our day was complete. They eked out the very last of the snow that was left behind!

I really appreciate that Mary! Thank you. I'm hitting the mark then - hoping to inspire and bring joy to those who stop by. Thank you again! Blessings, ColleenDelete
So many amazing ideas here - happy to have found your blog as I plan for our first year homeschooling next year!! http://learnathomejourney.com/ReplyDelete
So glad to hear that my blog has inspired you as you get ready to embark on your new journey of homeschooling. I pray it is a blessed one! Blessings - ColleenDelete
Oh what fun! Love the ideas and fun with science. I'm visiting from Weekly Wrap Up!ReplyDelete
Nita - Thank you for stopping by! We are having too much fun! Ha =) Blessings - ColleenDelete
I love how the simplest experiments can be such a hit! We have a chemistry set similar to the one you showed and the first experiment was just dissolving a colored tablet to make the water change color. My kids were in awe ;) Thanks for sharing your ideas!ReplyDelete
North Carolina! I wish I'd known. I was recently in Greensboro, NC followed by Greenville, SC. I would have LOVED to pop in on one of your fun studies!ReplyDelete
Michelle - Anytime you are near Raleigh, NC - you let me know! I'd love to see you! Blessings - ColleenDelete
