In science this month, we have been learning about the circulatory system. We began by researching the different parts and their functions: the heart, blood vessels, blood and lungs.
Next, we learned how blood transfers nutrients, oxygen and waste around the body by diffusion and osmosis. We did a fun experiment using skittles to show the ‘nutrients’ diffusing from a high concentration to a low concentration.
We also designed an experiment to answer the question ‘does exercise affect pulse rate?’ which we found that it does and then we learned the reasons behind it.
Finally, we discussed keeping ourselves healthy with a balanced diet to get the correct nutrients that need. We researched the different components of food and the positive and negative effects of them (eg. Sugar). We also looked at the many benefits of exercise.
