Class 5 have been very busy learning about the human body in our Science lessons.
Firstly, we investigated BLOOD.
We learnt many amazing facts about what our blood is made from:
55% is PLASMA. This is the liquid part of the blood and transports all the nutrients, proteins and hormones around our body.
44% is RED BLOOD CELLS. These transport oxygen around our body.
The final 1% is made from WHITE BLOOD CELLS – which help us fight infections, and PLATELETS which help us stop bleeding and enables wounds to heal.
To show what blood looks like under a strong microscope we made our own blood. We used the following ingredients:
Cooking oil = the plasma
Red jelly = red blood cells
White beans = white blood cells
Rice = platelets
We had a messy time creating!
We were also VERY LUCKY to do our very first DISSECTION this week!
Mr Glover generously gave his time to come into class and lead a dissection of a pig’s heart. The children (most of them!) thought this was great and really enjoyed cutting into the heart, lungs and liver!
