The Heart as a Pump – Science Spectacular, Manchester Science Festival “It was awesome and gross” was how one young visitor described his visit to ‘The Heart as a Pump’ exhibit – truly praise indeed! The exhibit, which was based in Manchester Museum, formed part of ‘Science Spectacular’ at the Manchester Science Festival. It was run by researchers from the Institute of Cardiovascular Sciences and Faculty of Life Sciences at the University of Manchester and proved to be a fun day for all involved. Participants began their tour of the cardiovascular system with an interactive display of animal hearts where they were encouraged to don surgical gloves and touch ‘real’ hearts. Children tried to match pictures of various animals to the individual hearts – whilst they found it easy to distinguish between the mouse and giraffe hearts we had on display, differences between pig and sheep hearts were less obvious. No one could believe how big our giraffe heart was. The anatomy of the heart was explained to older visitors by the researchers present and knowledge was consolidated with an informative poster. Feedback from young and old was extremely positive. “I liked messing with the hearts” “I have enjoyed finding out about the heart, especially touching the real ones!!!” “The hearts were cool!! Loved it …” “It is amazing. I didn’t know how big or small a heart was.” “I liked seeing the water flea through the microscope” Moving further round the exhibit, participants learned about the function of the heart. An opportunity to view the beating hearts of water fleas down a microscope and to try and count the heart beat under different conditions illustrated clearly how this may be changed. This was further explained in an ECG demonstration where measurements were taken on a very noble, an ultimately exhausted, PhD student at rest and after exercise. Children appeared to gain a lot of pleasure from making him run faster! An interactive model of the circulation (purchased with funds from the Physiological Society) illustrated the role of the heart and blood vessels within the body. Participants were able to pump de-oxygenated ‘blood’ to the lungs and oxygenated ‘blood’ to the rest of the body. They were then given the opportunity to think about what can go wrong with the circulation in disease. A particularly messy activity was our model of healthy and diseased arteries. By pouring ‘blood’ (actually fish tank gravel) through ‘arteries’ which were healthy and those which had atherosclerotic plaques in them children learned how occlusion of vessels slowed and, or prevented, blood flow. This was related, in discussion and on a poster, to heart attacks and stroke, and the importance of healthy lifestyle was highlighted. Children especially loved this activity and got extremely enthusiastic – we had to borrow a hoover to clear up all the spilled gravel/blood. “Lovely. Educational. Messy.” “It was brilliant! I liked dressing up.” Dressing up as a scientist was another popular activity. Children put on lab coats, gloves, goggles and hats as they learned the importance of safety in the laboratory. A parental photo-shoot followed for the majority of ‘scientists’. Participants were given a quiz sheet to work through as they moved through the exhibit consolidating knowledge gained and, as some questions were quite difficult, encouraging interaction with the research scientists. General information about the cardiovascular system was related to current research interests of the scientists whenever possible. Children were given a ‘goody bag’ to take home with colouring pencils and pictures, a word search and an entry form into our poetry competition. Although the closing date has not yet been reached, we hope the offer of prizes such as a microscope will encourage entries. We will post the winning entries on the Cardiovascular Research Group website. We also hope this will ensure that children will reflect upon what they have learned during their visit to our exhibit and thus continue their learning. Feedback about the event was excellent. All in all it was an exhausting but extremely enjoyable and worthwhile day. “Very entertaining and knowledgeable, very important and useful” “Wow! Lovely event; enjoyed it!” “Excellent day! Thanks to all the staff – my two children and I had a great day. Thanks.” “Loved the variety of exhibits. Great fun for all the family” “Excellent props and info provided by the workforce. I have thoroughly enjoyed the day! Thanks again!”
