Ospreys set up a comparative test to investigate how exercise affects your heart. During this unit, we have already learnt how important the heart is to our body, the different parts of the circulatory system and their jobs. We concluded that exercise increases your heart rate. We then thought of our own investigative question such as:

• Does leg or arm exercise increase your heart rate more? - Legs 
• Does a sprint or being chased increase your heart rate more? - Chased  

Year 6 set up a fair test to investigate how different types of exercise affects your hearts. During this unit, we have already learnt how important the heart is to our body, the different parts of the circulatory system and their jobs as well as learning all about heart heroes and villains. We found that tig increased our heart rate the most and the agility course increased it the least.
