Pupils learn about the circulatory system and the composition of blood, before
making ‘blood’ using ingredients to represent its different parts. Pupils discover
how blood is used in blood transfusions to improve and save lives.

If making the blood with food items, you will need these minimum
quantities per group of students:
•
7 white marshmallows (to represent white blood cells)
•
a handful of Cheerio cereal soaked in 2 drops of red food dye (to
represent red blood cells)
•
a teaspoon of hundreds and thousands (to represent platelets)
•
100ml of yellow liquid, e.g. orange squash / lemonade (to represent
plasma).

Giving blood saves lives. The blood you give is a lifeline in an emergency
and for people who need long-term treatments. Many people would not be
alive today if donors had not generously given their blood.

Team Margot Foundation was formed because of a little girl called Margot
who needed a bone marrow transplant. Margot’s family and friends came
together as
Team Margot
to help find her a matching donor and ask
people to do something amazing: register as potential stem cell and bone
marrow donors.
Margot wasn’t able to find her perfect match, but did eventually find a
suitable donor match and received her bone marrow transplant.
Unfortunately, Margot’s leukemia was extremely aggressive and she
passed away, aged 2 years and 2 months.
Team Margot continues to campaign for every individual that is eligible to
register as a stem cell and bone marrow donor.
Through the ‘Giving to help others’ education programme, the charity also
encourages organ donation, blood donation, stem cell donation and cord
blood donation.
