Our work, as HistoryNeedsYou, concentrates on communicating History by making it fun, engaging and relevant. We also apply our ethos to communicating other subjects including poetry, drama, literature, engineering and science. Here’s a fun way to learn a little bit of biology, inspired by a homework question.
Homework challenge: make a 3D model of a cell, animal or vegetable.
Homework solution: bake blood cell biscuits, showing white and red cells.
Make a biscuit (cookie) mixture, colour 3/4 red, form into blood cells and bake.
250g plain flour
125g castor sugar
Red food colouring
Plastic sandwich bags
Cream the butter and sugar and gradually beat in the sifted flour. Add ginger to taste. Make into a stiff paste. Set 1/4 aside for the white blood cells. Add red food colouring and a dash of paprika to the mixture for the red blood cells. Beat it in until the colour is even and of a good deep red colour. Form into small balls and place on a greased baking sheet. Press each ball flat with a round spoon to form the distinctive shape of a red blood cell. For the White blood cells, form into balls twice the size of the red blood cells and do not press flat. Bake in a warm oven until the biscuits are firm but only just browning. Ten to fifteen minutes at 180C is usually sufficient but ovens vary!
When cooked, remove from oven and allow to cool. When the White cells have cooled slightly, place a chocolate button on top of each one to represent the cell nucleus. The warmth will make the chocolate stick to the cell. Leave the biscuits to thoroughly cool before bagging up. Stick a blood-bag label on each bag. You can make your own or find one on the interweb. Add the biscuits to the blood-bags, ensuring a mixture of red and white cells.
Present your homework and hope for a good mark. If your teacher isn't impressed then you can eat the biscuits to cheer yourself up! Sharing biscuits with school friends is a sure way to increase your popularity!
