2nd Class

As one of the experiments for Science Week we made Ooblek.  Ooblek is a special substance that is liquid and can be poured but becomes solid when you put pressure on it.  Ooblek is a non-Newtonian Fluid.  It is also great fun to play with!

We have been doing a lot of work with magnets and this week we used a magnet to make a compass. We placed the magnet on some foam that was floating in a basin of water. The North Pole of the magnet pointed North straight away and no matter how many times we changed it around, it always turned towards the North. This is how a compass works.

During Science Week we used lemons to make mini volcanos.  We added a little food colouring and baking powder to make them erupt.  Lemon juice contains citric acid.  When you add baking powder to the citric acid  it reacts to form carbon dioxide and sodium citrate.  This causes it to fizz and bubble.

Our tastiest experiment for Science Week was cooking pizza.  We discovered that heating materials changes them in different ways.  The heat brought out all the flavours and the cheese melted.  Final result, a yummy slice of pizza.  We have also been doing fractions so we revised halves, quarters and eighths.

We have been learning all about magnets  and finding out which things in the classroom are magnetic. We did two experiments to find out more about magnets  and we discovered that magnets can work  through paper plates and also through glass. /

  With Halloween on the way we see pumpkins everywhere.  We drew our own to decorate our classroom.

We were all looking forward to our Halloween Fun Day  and it turned out to be great fun for everyone. In the morning we paraded around the school  and then watched as all the other classes parading around. In the afternoon we played Halloween games. We tried to bite an apple which was hanging up,  not as easy as it looks! We made Chocolate Apples and also Chocolate Lollies. By Home Time we were ready for our Halloween Break!
