Remember that all of my notes for this main lesson block can be found in much more detail on my website.
The Nation of the Great River
- begin by having the girls make a web on a huge sheet of chart paper -- "What do you already know about the human body?" -- using black pens to show prior knowledge
- finger knit with red a long piece of yarn and lay it out on the floor to be the Great River; add index cards with the names of the President, the Cabinet, and the different Departments
- read The Story of the Great River
The Circulatory System
- read "Heart: The Double-Barreled Pumper" chapter from Blood and Guts: A Working Guide to Your Own Insides, stopping as follows:
- at the end of page 49, watch the Meet the Heart video by the Khan Academy (this video happens to be a really good complement to the Great River analogy)
- at the top of page 50, do the Tennis Ball Squeeze activity
- at the top of page 51, talk about how a seashell sounds like the ocean but it's really magnifying the sound of the blood rushing through your head, do the Stethoscope activity, and use a blood pressure cuff to take your partner's blood pressure
- at the bottom of page 52, look at the Artery vs. Vein transparency (pictured above, also see note below) and then watch the How a Healthy Heart Pumps Blood video by the American Heart Association
- on page 54, do the Under Your Tongue activity
- at the bottom of page 55, do the Matchstick Pulse Meter activity
- at the bottom of page 57, do the Stress Test activity
- look at the human blood smear under a microscope, #25 from our set of 25 prepared microscope slides
- read the Amazing Facts on page 58
- review all vocabulary using the Circulatory System three-part cards from the ETC Montessori material for Human Physiology
Note: we didn't do these but "Returning to the Heart" on pages 16 & 17 of Easy Genius Science Projects with the Human Body: Great Experiments and Ideas has several neat hands-on activities that would be a very good follow up to the valves in the veins.
