Year 1 have had a challenging science lesson this week exploring whether materials are manufactured or natural. First, we explored natural materials and described these as materials that can be found out in the world either by being collected, farmed or harvested. Examples of these are materials such as wood, rock, iron, wool and sand. We then talked about manufactured materials which are those that don’t exist naturally and have to be created by being heated or by mixed with other things. Examples of these are materials such as plastic, polyester and paper. What we found very tricky is learning that some materials can be both. For example rubber can be natural if it is the sap that has come directly from the tree but it can also be manufactured using plastic and some metals are natural such as iron but others are manufactured such as steel. Year 1 also watched polyester being made in a factory from recycled bottles and found out that their school polos were made 65% polyester.
