In Science we have been learning about the human body. In one particular lesson we focused on the digestive system. We found out what happens to our food once we have eaten something. It travels through a number of different organs including the large intestine, the small intestine and the stomach before it eventually leaves the body. We recreated the digestive system by using a plastic bag to represent the stomach- we place food and drink into the bag. We then crushed the food that was in the bag and placed it into a pair of tights to represent the intestines. We then squeezed the tights and watched the digested food erupt from the tights.
6NW exercise and the impact on the body
We carried out a range of exercises and measured our pulse to see the impact these exercises had on our body.
6NW circulatory system
We recreated the circulatory system by using plastic bottles and straws.
In 6LJ we have been learning about the circulatory system. First, we completed a Burn2Learn activity, where we had red and blue card to represent oxygenated and deoxygenated blood respectively. The tables in the classroom had different labels for body parts on them. The children took their oxygenated blood to a body part where it became deoxygenated, then went back to the heart that pumped them to the lungs. After being oxygenated at the lungs, they journeyed back to the heart that pumped them out to another body part. Following this lesson, we looked at the heart in more detail. The children enjoyed creating a model of the heart using bottles, coloured water and straws to represent the ventricles and valves of the heart. They noticed how the blood only flowed in one direction.
6LJ - How nutrients travel around the body
In order to build on our understanding of the circulatory system, we re-visited year 4 science on the digestive system. We learnt that the nutrients from our food are taken out in the intestines, and we modelled this using an experiment. First, we crushed up biscuits, banana and some water in a plastic bag. This represented when we chew our food. Then, we added some orange juice to the mixture to represent the acid that breaks down our food in the stomach. Following this, we transferred the mixture into the leg of a pair of tights, which represented the intestines, and squeezed the liquid out with our hands. Our hands represented the muscles that our intestines use to squeeze our food along the digestive system and take the nutrients from our food. From here, the nutrients travel into our blood system.
