Year 8

Year 8 have been looking at different changing states during out current science learning. We have been keen for the students to think about everyday situations, and then to understand some of the science principles that are taking place.

One example was that of a boiling kettle. Mr Peters explained how he always fills his kettle to the top whilst making a cup of tea. Miss McNie has a smaller amount of water. We asked the Year 8 pupils to think of a scientiffic way in which we could test which was the most effective method to use.

The pupils carried out a practical experiment where we boiled two beakers of water. One beaker contained a high volume of water, whilst the other had a low volume. We made this a fair test by using identical bunsen burners as the heat source. The beakers were place on top of a tripod.

Year 8 timed how log it took for the water to boil in each beaker. We knew that boiling point had been reached when we could observe the water evaporating up the side of each beaker.

Our results were recorded in a bar chart in our science books. Our conclusion was that a low volume of water is quicker to boil than a large volume. The students were asked to display this data in an accurate bar chart that contained the correct gague on each axis.

Keys words for this experiment were: evaoration, boiling, high volume and low volume. This is all part of the learning intention to encourage scientiffic language and allowing the pupils to form their own conclusions.
