We recently finished up our unit on the circulatory system. Today, I want to share the worksheets and activities we did with this unit. The kids really loved this unit (and learned a lot too!)!
We started off with an overview of the circulatory system before learning about the heart, blood vessels, blood flow through the heart, blood transport through the body, blood composition (red and white blood cells, platelets), blood types, cholesterol, and diseases of the circulatory system. Plus, we did a number of hands-on activities that the kids really loved!
Today, I’m ready to share our packet and some of the hands-on activities that made this unit engaging for the kids! Our Circulatory System Packet is well over 40 pages!
So, here is what this packet includes:
- Circulatory System by Susan Gray
- Your Circulatory System Works by Flora Brett
- Your Circulatory System
Then we talked about the circulatory system in general. Over the first couple of days we did the Circulatory System and Heart worksheets (pages 4 and 5).
Once we had talked about the heart, it was time for a hands-on activity. We spent a couple of days practicing how to take our resting pulse rate. I had them find their pulse on their neck and had them count how many beats they could feel in 15 seconds. Then we multiplied that number by 4. We made note of their resting pulse rate.
Another day, the kids found their pulse rate while resting, while walking slowly, while running, while skipping, and then with the activity of their choice. One of my daughters jumped rope. Another ran up and down the stairs for a minute. Then we wound up finding all kinds of activities to do and check our pulse rate. I had the kids graph their results.
This activity was a huge hit!!
Next, we talked about the blood vessels – arteries, veins, and capillaries. One of the activities was to have the kids locate a few of the major veins and arteries (Aortic arch, Renal vein, Femoral artery, Jugular vein, etc.) We had reviewed the skeletal system before starting this unit, so the kids could see how some bones and blood vessels share the same name (like the femoral artery). They located these using the hand-outs you see below (which are in the circulatory system packet).
1. I took a huge piece of butcher paper and made an outline of the kids with pencil (yes, even my 8th grader did this!). The kids then made a dark outline with black marker.
2. Next the kids drew in some of the major organs. They studied some of the hand-outs to help them figure out where these were. I had them do the brain, heart, lungs, stomach and kidneys.
3. The kids used the veins and arteries sheets to help them start sketching in the major paths. I told the kids that they had to have pairs and their artery and vein had to join in a web of capillaries so they could do the activity at the end.
4.The kids then used red markers for the arteries and blue for the veins. The capillaries were webbing of red and blue. At a minimum, the kids had to have arteries/veins that ran to the brain, lungs, hands, and feet. My older two also had some veins/arteries leading to the other organs.
We spent quite a bit of time talking about how blood flows through the heart, to the lungs (to pick up oxygen), then goes back to the heart before being pumped out to the body (to drop off oxygen). We spent time looking closely at the heart hand-out (above) and blood flow through the heart. Then we were ready to trace the path blood takes through out bodies.
First, I demonstrated the flow of blood (I go into a lot of detail about the demonstration in the packet – which chamber blood enters from the body before heading to the lungs to pick up oxygen, etc.). Then, the kids did their own blood flow activity starting with 10 blue tiles in the heart… which had to go to the lungs to pick up oxygen (flip to red)… then back to heart before heading to the toes (or brain) to drop of oxygen (flip to blue)… etc. The kids *loved* this!!
What is blood made of:
Next, we went on to talk about what blood is made of.
- 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)
Then, we went on to talk about the different blood types: O+, O-, A+, A-, B+, B-, AB+, AB-
We surveyed 50 people about their blood types. We made sure to ask only unrelated people (no parents and children) to make the results as random as we could. But if you don’t have time, I included our results and you can use those instead.
Once you have your results, have the kids add up the totals. Then, have your students graph the results, using a different color for each column. Give them the US results and have them graph those results as well, using the same color for each blood type. How did your results compare with the national averages?
If you are interested, you can purchase a blood-typing kit (affiliate link). Although I know the blood types of my older two, I couldn’t remember the blood type of my youngest. She was eager to have do the blood typing kit even though it entailed pricking her finger!!
The kit includes a comparison chart once your blood has mixed in each of the water droplets. It was pretty straight forward to do!
Pages 43-56 of this packet have various lapbook and notebook pages (with various medical images) that you can use with your students if there is different material you want to cover. Plus, there are a couple of pages that touch on getting rid of waste (kidney) and on the respiratory system (lungs), which our family touched on during this unit.
Circulatory System Packet (answer pages are included)
The Circulatory System Packet is 40+pages. It is $4.75.
