Heart as a Pump:
|We did this experiment: When your heart beats it acts like a tennis ball filled with water. The heart muscle squeezes blood out of its way. Between beats it goes back to its original shape. The human heart creates enough pressure to squirt blood 30 feet. The kids had a tough time actually squeezing the tennis ball, but they got the idea.|
Circulatory System Activity:
This is how Harold looked before we started. I named him to pique the kids' interest!
|Heart and Circulatory Activity|
- the fluid is called plasma (corn syrup)
- red cells carry the oxygen (red jelly beans)
- white cells fight infection (white jelly beans)
- platelets help to clot and form scabs (rice)
We have moved to homeschoolden.com. In the years since we moved from this location, we've started creating lots of packets and worksheets. We have a number of science packets.... and our science packets are especially popular. We continue to do a lot of hands-on science [and history], which I think is why the kids love science and history SO much!
Digestive System Packet which includes lapbook pages, worksheets, plus our hands-on activity ideas.
We have a packet on the Skeletal System Packet which includes a half-dozen hands on activities.
We also have a packets on Earth Science, Cells, and more!
And this at some point soon, we will be studying the circulatory system again... and we'll be sharing a new packet on the circulatory system. Here's the sneak peek... It might be a bit longer once we actually dive into the unit. I purchased some nice graphics that I'm really happy with! :)
See you soon over at our new location: homeschoolden.com or over at our Homeschool Den Facebook Page. ~Liesl
