We have just started our new topic 'The Circulatory System' and over the next few weeks I will be posting some great teaching resources including, links to videos, worksheets and a wide range of activities that include experiments you can do at home!

Week beginning 30th March 2020


This week we are going to be looking at blood. You will find out what blood is made of, why we need it and the crucial role it plays in our circulatory system.


Hopefully you will enjoy watching the following video about blood. It is aimed at KS2 children, it is about 30 mins but if you are a bit squeamish you may may find a couple of the scenes a bit yuk!


Read the PowerPoint and then complete the activity showing the make-up of our blood. It will give you an opportunity to practise your pie chart skills!

How does BLOOD circulate around the Cardiovascular System? Here body parts and biology are explained to kids. Operation Ouch is a British science show for ki...

If you tried to complete the pie chart showing the make up of blood these photos show you the answer!

Remember a full circle is 360 degrees so 100% = 360 degrees. Therefore 1% = 360 divided by 100 which = 3.6. The red blood cells represent 45% of the volume so you need to multiply 3.6 by 45. This should give you 162 degrees (see photo 1 ,2 and 3)  Next I would do platelets as these are just 1% therefore 3.6 degrees. Finally the blood plasma is 54%. So, multiply 3.6 by 54 and this should give you 194.4 degrees. Look at the last picture.  3.6 + 162 + 194.4 = 360 degrees or the whole circle!




If you read my message today (Tuesday 24th) you will see that I suggested you complete an investigation in the garden today (while the weather is nice) The following is a useful framework - you will need to do a table for each separate exercise through as this only has one.  Try plotting 3 exercises on a graph. Good luck with it and don't forget to send me any results!

Human Circulatory System

This is a really useful video that you can watch. It describes how our circulatory system works in a child friendly way.
