Today’s post comes from Wellesley School.
A Day in the Wellesley Science and Technology Classroom
We have been doing a school-wide inquiry on time. As part of this study, the junior students are each making a clock.
This morning I went to science and technology and we started painting and putting the numbers on our clock. First we had to draw a plan for it and then we had to cut it out of wood. Today we got to paint it and make our numbers. I cut out a truck and I painted it brown. First people used coloured paper and we cut out shapes for the numbers. We had to be careful so they fit in our clock. Then we drew the numbers on with felt tips. We cut out a circle with lines and we used the lines to line up the numbers. We had to put them in the right place so the clock would be right and show the right time. Mrs Hawthorne said next week we will glue them on and varnish our clocks. The middle bit of the clock was where we had to drill it for the clock mechanism to fit through. The hardest bit was when we had cut out the wood and I really liked cutting it out.

Year Six having a quick fun lesson on fair testing.
When we came into the science room after our lovely morning tea break our science teacher Mrs Hawthorne told us that after our kitchen chemistry sessions we were doing something special. Our school belongs to the Hutt Science Centre and we have borrowed some Gazoom Rockets!
What we were going to do was very fun. We put down on a chart whether we would use 1,2,3 or 4 cm of water in our rockets and we all had 1 whole tablet (which was what was fueling the rockets). Me and my partner chose to put in 2. Then we went outside. My partner was to stand and watch while I launched the rocket. I put in the tablet and then stepped back. Whoosh! The rockets went up off their bases. Although some just fizzed. Our rocket was the second highest! We were very proud. From the results we had to decide what was the best amount of water to react with the alka seltzer tablet to make the rocket go the highest.
The second time we did the same thing except the rockets all had 2cm of water because we found this was the amount of water that fired the rockets the highest. The variable we could change was whether we wanted one or half a tablet. We chose half. This time I was watching and my partner was launching. Again whoosh and fizz! The rockets came up again (and down). This time our rocket only went up a little bit although one of my friends, Sam, his rocket went way high up.
I think this was a really fun session and I loved it. If you want to make a Gazoom rocket go high, use 2cm of water and half a tablet.

Classes from Year 6 up are introduced to the basics of Lego Mindstorm programming.
On Monday afternoon 7N had their second robotics session. We have been learning how to programme lego mindstorms. Today we had to programme our robot so it touched a wall, turned and reversed before going back the other way. We also had to make it do a 360 turn. Once Mrs Hawthorne could see that we remembered those basics, she set us a couple of more difficult challenges. We learnt how to add an extra motor and how to use the sound sensor. We had lots of fun adding to our robot and building extra parts on our robots. My group, me and Blake were very successful in programming.
Mrs Hawthorn helped us when we were stuck and she made it a much better experience. 7N really enjoyed robotics and the range of our ideas was fantastic!
Thanks for the session, Mrs Hawthorne and we hope to come back soon.
