This year we're working on Preschool Themes. You can check out this post for our learning goals) One of the big themes we're working on is the Human Body. The most recent section was Heart and Lungs.
As always, we read a ton of books! He really seemed to like A Drop of Blood, probably because it starred a vampire.
This was one of those times when an activity seemed great in my head... but didn't quite work out. The idea was to have Xander see how much water he could pump using a hand pump in 30 seconds. Then we could discuss how his hand got tired, but his heart pumps all day and night. I'd done a similar activity in a 7th grade classroom and it worked out wonderfully. Unfortunately, I picked up a cheap bulb from Wal-Mart, not knowing that it didn't have a valve inside, so it made a horrible pump. Next time, I definitely need to invest in a good rubber pump with a valve. You could also add a hose clip to simulate clogged arteries and see how much harder it is to pump.
Model of a lung
We made the very popular model of a lung. Cut the bottom off a two liter bottle and stick a balloon inside. Then cover the bottom with a bigger balloon, or heavy piece of plastic. The little balloon simulates the lungs while the bottom simulates the diaphragm. Push up on the diaphragm, and the lungs squeeze out the air. Expand the "chest cavity" by pulling down on the bottom portion, and the lungs fill.
Listening to Our Hearts
I picked up this inexpensive stethoscope for Xander. He has really enjoyed listening to everyone's heart! He likes to compare.
We did two Alphabet in Simple Science posts for this unit. We did B for Blood and H for Heart. Be sure to check them both out for fun activities!
We made a simple sensory bin out of red kidney beans, some googly eyes, some skeletons (left over from Halloween) and some straws and balloons. As you can see, Xander dove right in.
Blood Sensory Bin
We used red water beads (which somehow ended up pink) for red blood cells, ing pong balls for white blood cells, and little glass gems for platelets.
We watched a few YouTube videos, as well as Magic School Bus Works Out
Since I'm having trouble being consistent about math, I have started having Xander do 10 minutes of either Splash Math or a Math Age 4-6 app. We also try to incorporate math play when we can. Here he is
making a mess with learning with his number board. After a while of free play, I had him skip count by fives.
He also played with his Inchimals.
