While home learning, Year 4 learnt all about teeth and tooth decay. You can see some of the fantastic work below. As part of our Science learning, a dental nurse called Jenny made us a video tour of her dental surgery and talked to us about tooth decay. She then set us the challenge of making her some child-friendly leaflets for children our age to go up in her dental surgery.
We were able to use our Science learning to put together our brilliant informative leaflets, some of which you can see below. We sent them off to Jenny and she has put lots of them up in her surgery for children like us to read!
This week, we focused on the parts of the human digestive system in our Science lesson. Some of the children made models of the digestive system with things they had at home. Here are Harrison and Emelia’s models.
Our topic in Science lessons this term is Teeth. The children had a look at their own teeth in the mirror to identify the location and shape of the different types of teeth. They then investigated the roles of different teeth and explained their purpose. Finally, they made models of each type of tooth. You can see the results below!
Tooth Decay Investigation
Year 4 have been investigating tooth decay by looking at the effect of different liquids on egg shells, using egg shells to represent teeth. Here are some of the experiments they have been doing at home.
Molly's experiment. Molly has used Pepsi and wonders whether this will have the same effect as the Coca Cola Miss kerlogue used.
The children in school have been doing their own egg experiment.
States of Matter
This term in Science, we have been learning about states of matter. Here are some pictures of us considering the properties of materials. Eventually, we worked out that we could group them as solids, liquids and gases. You can also see some pictures of us investigating what happens to solids like chocolate buttons when heat is applied - they melted!
