This week we have been learning about the Skin, Hair and Nails
If you missed the other parts of our Human Body Study, you can see them here: Human Body – Doctor’s Bag, Human Body ~ Body Parts, Human Body: Bones, Joints and Muscles, Senses, Cells, Heart, Blood and Circulation, Digestive System and Nutrition, the Brain and Nervous System, the Skin, Hair and Nails, the Immune System and Germs, the Respiratory System, the Excretory System, Reproduction System and Dental.
I got the idea for this edible skin model from Once Upon a Family.
The mini marshmallows at the bottom of the cup represents the hypodermis. This is the inner and most thickest layer of the skin. It is made up of cells that specialise in accumulating and storing fats.
The layer of strawberry yoghurt represents the dermis. This layer contains blood vessels that help you regulate the temperature of your body. It also contains a network of nerves and receptors that help you with your sense of touch, pressure and pain and is also where your hair follicles, sweat and oil glands are located.
The layer of broken up biscuits is the epidermis. This is the outer layer of skin, the part that you see everyday. The dead cells on the outer part of your skin sheds, constantly being replaced with new cells.
We used sticks of celery to represent the hair and chocolate chips to represent moles.
I also made a mini pack on the Skin, Hair and Nails.

While looking at the skin, we talked about our fingerprints as well. I got the idea for these fingerprints from Highhill Homeschool.
The boys made a fingerprint with black ink and then I scanned it and increased the size till it fit on an A4 piece of paper. Then they used markers to create patterns on their fingerprints.
Fingerprints are tiny ridges on the end of your fingers and thumb. In the 1900s, they started realising that no two prints were the same. Fingerprints can be described as having patterns of loops, arches or whirls.
