Science Week

We did lots of interesting things for Science week.
Paper Rockets
We made these rockets with paper by wrapping one strip of paper around a pencil. We sellotaped the top to trap the air and put a picture of a rocket on top. Then we inserted a straw in the paper cylinder we had created and we blew our rockets. It was great fun.

Larger rockets
We made these large  rockets by wrapping an A4 sheet of card around a metal template. Then we cut out a circle and cut a slit and turned it into a cone shape to form the top of the rocket. Next, we brought our rockets outside and teacher had a special rocket launcher and we each placed our rocket on the launcher in turn and pumped air into it. When we released a valve our rockets went flying into the air and we ran to catch them!!

The Bubble Show
We went to see a bubble show yesterday in the halla. We saw some huge bubbles and learned some interesting facts about bubbles. We saw that it didn't matter what shape the bubble wand was (we saw star wands, rectangular wands, cubic wands and triangular wands) - the bubble still came out in the shape of a sphere. We got a chance to look at giant bubbles and we observed that all the colours of the rainbow (red,orange,yellow,green,blue,indigo and violet) are visible at first in the bubble. When all the colours disappear the bubble is about to burst. If the bubble wand was very big then the bubble was very big also. We also saw a bubble filled with smoke, a bubble within another bubble and several bubbles joined together. To make the bubble mixture you will need a fairly large container filled with water. Add 1% glycerine and 4% washing up liquid. Mums and Dads will need to give a hand making the mixture!
