Based on Great Lesson Three, Eldest did a project on Germs and Middly did a project on microscopes.
Daddy bravely pricked his thumb so that Middly could make some slides (using a little with human blood, and Eldest could observe Daddy’s thumb as it healed.
Here’s Eldest’s description of Daddy’s the healing:
I’m very grateful for Daddy sustaining an injury for the sake of science. I tried to stab myself in the thumb with a pin, but wimped out.
I did manage to provide Middly with some hair, though. So he made a slide with that. Once again, he drew what he could see at various levels of magnification:
I also got out a Microscope Kit and Middly built a microscope.
I meant to take a photo, but I forgot. So, here’s Middly’s drawing instead:
Middly talked about the effects of convex mirrors and how to put a slide together. I was rather pleased with his pictures.
They both drew a lot for this project.
Eldest drew a picture of germs in a body.
He talked about the invention of penicillin and of vaccinations.
He showed us a picture of bacteria being engulfed by macrophage, which he’d copied from a book.
Eldest particularly enjoyed using The Human Body Sticker Book by Usbourne for this project, and I was impressed by the level of detail.
