Science club – Circulatory System

Week Five – Circulatory System

Arrival Craft: Paper heart from Scholastic model book.

Introduction: Today we’re looking at the circulatory system. Does anyone know what the circulatory system does?

The circulatory system moves blood around our bodies. What organ pumps all the blood around our bodies?

The heart is a big muscle that pumps blood around our bodies.

Does anyone know where their heart is?

If children are unsure, ask a volunteer to find the heart on the anatomy model.

Individual task: Children can make hearts out of plasticine and put them on paper people. body 

Gather Together: We’re going to do something a little bit different today. I have several activities that we can only really do one or two at a time. So, I’m going to put a different activity on each table. When you finish with the activity on your table move around to the next table. Everyone will get a chance to do everything and, when we’ve all visited all the tables, we’ll have snack time.

Set up microscope on one table so children can look at blood cells.

Set up heart models on another table so children can look at the hearts, take them apart and put them back together.

Set up blood pressure monitor and stethoscope on another table so children can have a go at taking their blood pressure and listening to one another’s hearts. bloodpressure

Set up CPR dummy on another table so that children can practice CPR. (These can be pretty pricey, but they make inflatable ones now, which the kids love see details here.)

Break for drink and snack.

Gather Together: What is our blood for?

There are four main components of blood and they each have their own job: red cells transport oxygen, white cells fight viruses, platelets build scabs, plasma transports nutrients and hormones.


Individual task: Make models of blood, using sweets to represent the different types of blood cells. bloodcells
