We have been learning lots more about Materials in our Science lessons this week.

We looked at a tray of different materials and talked about what we could do to them to change them. We then thought of some words to describe what happened to the materials. We came up with some fantastic words- squashed, stretched, bent etc We then thought about the properties of the materials- what makes each material special.

We took part in an investigation to see how strong four different materials were. We used card, wood, metal and plastic and added a 100 gram weight to the end of each. We talked about it being a fair test and made sure the rulers were the same length, we used the same weight and put them right at the end and we used the same amount of sellotape. We all make a prediction before the investigation started. We saw that the metal ruler did not bend at all and measure how much the others ruler bent in cm's writing out results in a chart and then drawing our own bar charts.

The investigation made us think that metal is a strong material as it did not bend with a 100 gram weight. We will try it next time with a heavier weight.
