Last week, we went to our medical sciences museum. They have a temporary exhibit that we hadn't seen yet called "Nanoworld." It has a lot of hands on activities dealing with things that are microscopic - including blood. One of Alexandra's favorite activities was playing in a "drop of blood." It was actually a red tent full of red balls. Hidden within the red balls was a white loofah. (sp?) It was, of course, a "white blood cell" amidst all of the red blood cells. (There were actually supposed to be several, but we only found 1.) This activity was supposed to show how in a drop of blood are lots & lots of RBC's, but comparatively very few WBC's. The kids enjoyed taking turns hiding the WBC & then searching for it.
Today, we got a very cute, scientific book from the library. It's called A Drop of Blood by Paul Showers. We also read Me and My Amazing Body by Joan Sweeney, a great author.
