To bring together all of our learning on the blood and circulatory system, we have all created our own bottle of blood. We used red and yellow food colouring, cheerios, marshmallows and oats to represent each different part of our blood – make sure you ask us to explain at home exactly what we did and why! Over the course of the last few days, we have all written a factual report which explains the main components of our blood, using our bottle of blood experiment as our inspiration.
