DMIC Problem Solving

Today we did DMIC Problem Solving in groups of four. Shylah was the questionnaire, I was the writer, Jorgia was the presenter, and Jess was the reader. The problem asked us to figure out how many cookies a child had eaten on the first day of five. The kid had eaten one hundred cookies in total.

First we took away six from a hundred five times and soon after realised that strategy didn't work. We then tried to divide one hundred by five. That strategy didn't work either. Then we tried guess and check. We started with the number fifteen. we added six to the four times and got the following numbers. Fifteen, twenty one, twenty seven, thirty three and thirty nine. We added all those together and got one hundred and thirty five.Then we tried ten which was to, high, five was two low, and then we tried eight.

The numbers were eight, fourteen, twenty, twenty six, and thirty two. We added all those up and got one hundred! We were really excited at our lucky guess. We were then chosen to present our work as we were the only ones to guess the answer. We got asked lots of questions by Whaea Kataraina and didn't really know how to answer some because we didn't think that far ahead.

When we sat down she asked us to figure out how many cookies the child at on the seventy sixth day. Our group was around two hundred off. That was ok though. The answer ended up being four hundred and fifty eight.

    Your group worked really well together including the presentation. The questioning was so that other groups could understand how you got your answer. It also helped your group to think about how you worked out the problem. Excellent work.

Science Roadshow

 On Tuesday the 30th of March, the Science Roadshow came to Otaki College with many different gadgets and gizmos to show us. They showed us experiments involving fire and explosions and lots of gases and balloons. It was very interesting to see. First when we got inside   there was already a few classes sitting down. we sat to the right of them and began listening. Two lady's were talking to them about something they had previously done. She soon got onto us and began the show. A blonde haired girl  introduced herself as Jess and her brown-haired friend was Steph. Jess said they would be talking about gases and asked if we knew any gases. Lots of people had good ideas and raised their hands.  When that was done she demonstrated some experiments. Lots of them involved fire. One of them had a gas blowing about candles without touching them. It blocked the oxygen from reaching the fire. The gas was called carbon dioxide (CO2).  They showed us a few more experi...
