Blood

I've been getting the question 'why do we have blood?' recently so decided to do a mini unit on it. We started by watching the Brainpop video then exploring the different components of blood (with sweets) and the different percentages of each in the blood.

We explored blood under the microscope - mine! the things we do for education : (

I hooked the microscope up to the PC so they could look at things in more detail.

They also explored the circulatory system and discovered the difference between veins, arteries and capillaries - which they recorded on a nice poster.
