Whizz! Bang! Pop!

We have had so much fun completing our Science Experiments during our Whizz! Bang! Pop! Inquiry.

Here are some photos from our Magnet Maze experiment where we discovered that Magnets have two poles, we call one the north pole and one the south. Depending on which poles you place together they can either attract each other or repel. Opposite poles attract.

Our Static Electricity experiment was so noisy… watching everyone’s hair go in the air was absolutely hilarious. We also made an aluminium can roll across the table without touching it. Here’s how it happens…

Rubbing the balloons against woollen fabric or your hair creates static electricity. This involves negatively charged particles (electrons) jumping  to positively charged objects. When you rub the balloons against your hair or the fabric they become negatively charged, they have taken some of the electrons from the hair/fabric and left them positively charged.

They say opposites attract and that is certainly the case in these experiments, your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it. This is similar to the aluminium can which is drawn to the negatively charged balloon as the area near it  becomes positively charged, once again opposites attract.

We follow up most of our experiments by writing a science report which lists the materials used, the procedure to follow and what happens during the experiment.

Here are some links to some great Science websites that we have used in class.
