As part of our studies in ‘Animals, including humans’, Year 6 have been investigating the human circulatory system and the functionality of the human heart. The pupils covered a range of science skills when they took a (very!) close look at an ox's heart. As the heart of an ox is similar to that of a human, the dissection gave the children a real insight into the human circulatory system.  The Throckley scientists carried out a careful risk assessment to ensure that everyone stayed safe during the lesson.  At first, some of the children were a little nervous about getting so close to a real animal heart, but once they got started, they were fine, and it was interesting for them to see such a vital organ up close. Before the teacher did any dissection, the class observed the external appearance of the heart and  observed that muscle is red, and fat is white. Then, the teacher – very carefully – sliced the heart open so that the children could identify and discuss the important sections of the heart.
