This week my kids learned all about the components of blood and the functions of each of those components in an engaging experiment that made for some learning fun!
Baby food jars with lids
Red vines or red hots
First add the corn syrup to the jar. The corn syrup represents plasma.Plasma is a thick, clear/yellowish liquid. Plasma is 90% water and contains nutrients, proteins, hormones, and waste products. They make up about 55% of blood volume.
Next tear up pieces of licorice or add the red hots to represent the red blood cells. Red blood cells carry oxygen and carbon dioxide through the body. Red blood cells die about every 3 months but are continually produced in the bone marrow. They make up about 44% of blood volume.
Add a few marshmallows next. The marshmallows represent the white blood cells that are responsible for fighting infection and other foreign invaders. They make up about 0.5% of your blood volume.
Last add the sprinkles, they represent your platelets. Platelets are responsible for clotting your blood when you get a cut or injury. They make up about 0.5% of your blood volume.
Now you have a great model of your blood! So cool and so educational!
