Today was the first formal day of home school. Momma went over the scientific method and tried to highlight the parts that was pertainent: (1) Pose a question, (2) Do an experiment, (3) Analyze the data and (4) Make a conclusion.
Today's experiment was based on the stomach (based on the theme of the human body that the Alpha's are studying). Applying the scientific method, the question was "How does the stomach and intestine work?" Momma took a pink balloon and S coated it with vegetable oil (stomach lining and enzyme) and filled it up with broken pieces of bread. After the last piece of bread, S poured in white vinegar (stomach acid). Momma blew up the balloon until it was the size of a fist (slightly bigger) and momma and S took turns shaking up the content and then poured a little bit out. S observed the that bread was broken up.
Then momma dumped the vinegar out, and S and momma took turns squeezing the balloon (now it was an intestine). Then momma poured it out and S observed that the food was broken down even smaller. Then, momma just let S squeeze everything out of the balloon. S pretended it was poop. Momma thinks that this was probably her favorite part of the experiement.
Momma asked what S concluded and S said that the job of the stomach and intestine was to break down the food. Momma really enjoyed doing such a simple experiment because it got the idea across so well and thinks S did too. Momma followed up the experiment with the chapter on Digestive Systems from the book Organs by Nancy Winslow Parker. Afterwards, momma and S did some simple craft with foam cubes.
Of course, it's still not perfect. Stripey and piano practice got neglected... but overall, Momma really enjoyed the first home school day.
