We're gearing up for a lengthy study of the human body. This week, Tessa learned about cells by taking a look at a rather large example that can be seen without a microscope!
Thursday
- Watched Bill Nye the Science Guy: Cells DVD by Disney.
Friday
- Read Greg's Microscope by Millicent E. Selsam.
- Completed RSO Cell Lab #1: An Egg is a Cell.
This was a great quick and easy lab that provided some basic hands-on knowledge of one special type of cell. Next week, we'll dip our toes a little deeper.

| Tessa inspected the tiny holes of an egg shell. These holes allow air and water in and out of the cell. |
 |
| After comparing her lab diagram to a real egg, Tessa labeled and colored its parts. |
 |
| My sister provided home-raised eggs for this lab. As a bonus, we cracked open an immature egg that one of her chickens laid a wee bit too soon (on left). Tessa correctly deduced that no chick could have hatched from this egg because it lacked its cell parts (yolk and blastodisc). |
