red, white & stained blue…

The cell lab at the Science Museum was pretty impressive. Grace choose to learn about red and white blood cells by looking at sheep’s blood under a microscope. To do so, she had to prepare a microscope slide by spreading a small drop of blood across the slide. After it dried, she dipped it into a blue looking dye which stained the cells so they could be easily seen under the microscope. Following the step by step directions at her workstation, she was able to identify the red and white blood cells, and the relative frequency of each.
Pretty cool given she did absolutely everything by herself following only the written/video instructions at her lab table.
Also pretty cool that Grandma & Grandpa stayed and watched the 20 minute process
