Class 4's science day theme was the circulatory system. We learned about local scientist William Harvey and his discovery that the heart pumped blood around the body. We took our own pulse before and after exercising to find out how much harder our hearts had to work. We also examined some sheep's hearts, cutting them open to see if we could identify the different parts.
Using cardboard, split pins, aluminium foil, copper tape, elastic bands, masking tape and anything else they could find in the classroom, the children were asked to design and build their own switch to operate an electric circuit. There was an amazing range of designs and ideas for activating the switches, including pressing, pushing, pulling, lifting and twisting!
We have been looking at the work of the American artist Jasper Johns, who created several paintings of the US Flag. When we studied them closely, we could see, beneath the paint, that he had first applied a collage of newspaper and magazine cuttings. We wondered about why he had done it and whether his choices of collage materials was intended to say anything about his country or life there. As we have been learning about the United Kingdom in our Topic lessons, we decided to create our own versions of the Union Jack, choosing collage materials that we felt related, in some way, to Britishness or British life.
We had a lovely time on our minibeast hunt, searching for different types of creatures in the school grounds. After trying to identify them all, we recorded their habitats and thought about what distinguished them from each other.
