It’s Science Week, an annual celebration of all things science and technology!

So to help celebrate, Dr Rina Fu a biomedical scientist and university lecturer, joined Bec and Jeziel for some cool experiments. Dr Rina is fascinated by how the human body works since a young age. “I think science is amazing…And teaching about science is just helping us be aware of the world that we live in and how it works.” She is also known as the “Mad Scientist Mummy” after her story book character. “There is a little nice plot to say, hey guys the mad scientist is not always the Einstein look with the explosive grey hair. It can be a female scientist.”

Today they kicked off by experimenting with blood. Jeziel dropped some of his blood in two different test tubes. One contained water and the other contained saline solution. Jeziel’s hypothesis was, “In water it’s just gonna chill. In the salt water it will separate and go see you later.” When you donate blood they need to find out your blood group. This involves removing the plasma and white blood cells to leave the red blood cells. The red blood cells are suspended in the saline solution which preserves the red blood cells. The low osmotic pressure difference prevents it from popping.
