It’s Bloody Good Fun

Our science lab this week was all about blood (this lab can be found in our science curriculum, R.E.A.L. Science Odyssey).  Molly has been eagerly anticipating this one for 2 weeks, while I kept forgetting to pick up lentils so we could complete it.  Finally, this week, we had all the supplies… it. was. on.

First, we discussed the 4 main blood parts:  Red Blood Cells, White Blood Cells, Plasma and Platelets, and their jobs:  carry oxygen to the body, eat bacteria/fight infection, carries food and keeps things moving, and clots blood to stop bleeding.  There are lab pages with the curriculum that include a drop of blood drawing, with clues for the student to use to identify each part in the drawing.  She then colored it and labeled it.

Now it is time to mix up the blood!  Supplies needed:

1/2 karo syrup

1/2 c red hot candies

5 lima beans

1 tablespoon lentils

wide mouth jar, spoon

First measure and pour the karo syrup into a wide mouth jar and idetify it as the plasma part of the blood.  This is what keeps blood viscous.  Next add the red hots, which are representing the red blood cells (RBC).  Then the lima beans, which represent white blood cells (WBC), and the lentils, which are acting as our platelets.  Stir!

Molly really enjoyed this and learned the 4 parts, no questions asked (I know because I told her I was writing this and forgot them… thank goodness for her help.  😉 )  While the model doesn’t do anything exciting, I think the hands on experience and reviewing what each thing was as we dumped it in really provided a fun way to learn.  Afterwards there was a lab sheet to fill in and also a space for her to draw the lab.  She has since made me promise we could keep the model until my birthday.  I’m calling this one a success!
