Week 3 for Wonderful Wednesday was filled with Mohawk Indians, as we dressed up to recreate the Boston Tea Party crew! It was especially fun for Sarah and I to find a way of taking her long hair and making it into a mohawk (short of cutting it all off)! I enjoy the costuming each week and finding ways to do various things. I love a good creative challenge and it's so much fun for me and her! What might be overwhelming for others, is a source of joy and fun for us.
Dressing up is definitely an optional thing. Dress up to whatever level your kids enjoy and you enjoy. We are extreme over here at Wonderful Wednesdays, but don't feel you have to do the same. A hat, a paper made costume element or a full costume bought or made; or even just a hairstyle for a week - is enough if your kids are having fun and learning more about that piece of history! So go for whatever brings joy and fun to your homeschooling day!
We began our morning with lapbooking through the current week's CC memory work and busting out in song while doing our hand motions through the timeline as well.
We dove into the science of the muscular system this week. I began our study with a few facts about muscles. We talked about the three types of muscles and discussed the difference in function and the appearance differences under a microscope for each one (which they looked at later under a real microscope).
The first activity we did was to figure out how much our muscles weigh. To calculate, you weigh the child and multiply the number by .40. The muscles in our body account for about 40% of our total weight!
Next we did a demonstration of how muscles alternate with contracting and resting. The kids lined up and then they alternated standing up if they were the muscle contracting and squatting down if they were the muscle resting. Muscle fibers alternate between states of contracting and resting.
We made a model this week, of hand muscles that worked when you pulled on the strings.
To demonstrate that our muscles are always alternating between a state of resting and contracting, we did an experiment with a paperclip and a knife. The kids unfolded the paperclip and then made a V shape with it instead (really was more like a U). Next, they put the paperclip on the knife and tried to hold it as still as possible with their arm off the table holding the clip just touching the table. The paperclip would then "walk" it's way down the knife as their muscles alternated contracting and relaxing! The more still they tried to hold the knife up, the more the paperclip would walk.
One more opportunity was given to the kids to explore how their muscles help maintain the center of gravity. They were given a ruler and told to balance it on top of their two index fingers and then using one finger. They noticed how their muscles compensated to always maintain the center of gravity so it wouldn't fall.
All in all, it was a Wonderful Wednesday!
