Science in Year 4 Beam class

The Beams have been in their element during Science this half term. They quickly rose to the challenge of creating a functioning electric circuit after being presented with crocodile wirers, buzzers and batteries with no guidance whatsoever on how to fit them all together. Now, they are not only able to name the parts of a circuit, but also know how to set one up efficiently to test equipment before seeking to integrate new elements into it. 
And what an array of items they have experimented with! String, paperclips, aluminium foil and elastic bands and nails have all allowed the children to work out the properties of electric conductors and insulators and become more skilled and confident at working with others to solve a task. The only challenge that remains is to regulate our voice volume a little more efficiently—-  due to the children’s contagious excitement, Science in Beam Class is never a quiet affair!
The children were fascinated that a pencil may be either a conductor or an insulator depending on where you attach the crocodile clip; and when one pencil refused to cooperate, it was our Science wizz Chris who suggested that the lead inside the pencil may have snapped due to potential rough treatment of our important writing utensil. 
Not surprisingly, our lessons got a little messier as we started to experiment with potatoes, strawberries, bananas and lemons! Setting up for our comparative tests on these potential conductors and insulators has allowed the Beams to develop a deeper understanding of fair and reliable testing and the importance of keeping some variables the same during an experiment so as to be able to draw reliable conclusions from observations.  This was a tricky concept for some in the beginning, but now it is children like Daniel who remind Miss Rieger that comparing a chicken with a kiwi bird would not make for a fair test, because a kiwi is bigger than a chicken! 
Three cheers to Beam class for embracing their Science this half term with such enthusiasm. Parents, carers and family friends-do not be surprised if your children ask you to try and experiment further at home, but rest assured that we have asked them to only do this after consultation with all of you!
