My girls have really gotten into Science Experiments lately. I think because they are so fun. If you have not done any with your kids because you feel you don't know what to do I have a few pretty easy ones that are great for any age on our science page that you should check out.
When doing these experiments with young children it really is more about the fun than the science. I do however try and explain the science behind it but I am not sure they really listen to me. For this experiment the acid (vinegar) is reacting to the sodium bicarbonate (baking soda) and forming carbon dioxide (the bubbles). When the reaction occurs the bubbles make the raisins dance (the fun).
My youngest was not really sure what we were doing at first. She was sick the whole day and when I brought her to the table and told her we were going to do Science she just went along with it. However when my oldest poured the Vinegar in and the raisins started dancing she got VERY interested in what was happening. We ended up adding more baking soda then more vinegar then more baking soda to get the bubbles several times. Then we cleaned the glass and started over again.
Do you do Science Experiments with your kids?
1 Clear Glass
1 Cup Water
3 or 4 Raisins
1 Tablespoon Baking Soda
1/2 Tablespoon Vinegar (may need more)
Pour 1 cup water in your cup, then put your raisins in.
Pour 1 Tablespoon Baking Soda in the water and stir.
Now pour your vinegar in, if the raisins don't dance add more vinegar.
It took my little one a minute to see what was going on, but my oldest thought it was really cool.
We ended up adding more vinegar so the raisins would dance again.
Science is so cool!
We added some more baking soda here to get them to dance again. At this point we could add either one and our raisins will dance.
