First we investigated Electrodough. We made up circuits using an electrodough and discovered it was a conductor and therefore it allowed our LEDs to light up and our buzzers to buzz. The following day, we created cartoon strips to show what the electrodough did - keep your eyes peeled as you should see them up around school soon.
This week, as it was science week, we spent a little more time than usual doing science! First we investigated Electrodough. We made up circuits using an electrodough and discovered it was a conductor and therefore it allowed our LEDs to light up and our buzzers to buzz. The following day, we created cartoon strips to show what the electrodough did - keep your eyes peeled as you should see them up around school soon. After this we continued with our normal science lesson, which this week was to make ice cream! The children were very excited about this and even more pleased when they were told they could try the ice cream too. They also learnt something about solids and liquids as they spotted that the ice and salt mixture had melted, whilst the milk, vanilla and sugar mixture had frozen.

This week in science we looked at ice. First of all we identified that ice was a solid form of water. Then we observed what happened when we handled it, we noticed that as it melted it got smaller and became smoother. We also noticed that the edges of the ice became more transparent but the middle of it stayed opaque. After that we carried out an investigation to explore what temperature ice melts at. We had lots of different predictions and were quite interested to discover there was not an exact temperature that it started melting at but that it was over 0 degrees centigrade. Below is the recording of the temperatures as an ice cube melted, which we took using a data logger. |
