 * 1) Read through p24-5 of Exploring Science 8
 * 2) Look at the dissection of a heart to see how it works. How much to you remember? See if you can correctly [|label the different parts of the heart]
 * 3) Look the animation to see the difference between the different types of blood vessel
 * 1) Complete worksheets on [[file:dcsks3science/ES8_CHAP_Bb5.pdf|the circulatory system]] and [[file:dcsks3science/ES8_CHAP_Bb8.pdf|blood and circulation]]
 * 2) Extension: Complete the worksheet on [[file:dcsks3science/ES8_CHAP_Bb10.pdf|Blood]]
 * 3) How quickly does your heart rate recover? [[file:dcsks3science/ES8_CHAP_Bb3.pdf|Measure it after exercise]] (n.b. this will take about 15 mins - do the exercise as a class and just record the results in a table, measure beats per 15 seconds and multiply by 4 to calculate beats per min)
