Ashley and Jye Yin tell us all about the science fair that has been happening at Hillcrest Normal School this week...
All of the senior classes took part in a science fair this week. Room 22
and 11 did light, Room 23 and 9 did simple machines, Room 10 did fire and Room
8 did magnets. We all had set up a table with an experiment.
One of Room 8's
experiments was showing people how to make a magnet. What you do is you get a
pin and a magnet then you stroke the magnet along the pin but only stroke it
one way. You need to stoke it 25-50 times. What happens is the magnet pulls all
of the atoms in the paperclip to face the same way, and that is what creates the magnet. In a
magnet all of the atoms are facing the same way but in a pin they are all
facing in different directions. We had some special visitors at the science
fair, Mrs Frizzle(a character from the magic school bus) and Mrs Ryan (an old science teacher at our
school). They came to open the science
fair. We all had lots of fun and learnt heaps.
