Energy For Tomorrow
27 August 2012

The senior school have been having fun with science.  As part of our 'Energy for Tomorrow' topic Science Alive visited.  We had a hands on session with electrical equipment to learn about parallel and series circuits.  We had to predict materials that could conduct electricity and found out that rubber is a good insulator.  We also got to make our own night light to take home.  

"It was interesting finding out how circuits are built"- Sydnee “I liked looking at the series and parallel circuits" -Polly

"I really liked making my own night light it was cool" - BJ

The next part of our learning will be carrying out a range of science experiments to understand the importance of a fair test. You conduct a fair test by making sure that you change one factor at a time while keeping all other conditions the same.  We will also be learning about renewable technologies: wind, water, biomass and solar because we believe we have a moral obligation to sustain the energy in our world.

 

Otago Problem Solving Challenge
27 August 2012

Seven Year 6 students are taking part in the Otago Problem Solving Challenge.  Otago University create problems for able Year 7 and 8 students to complete but also open it up to a few Year 6 students.

Over the course of two terms the students sit five 30-minute tests, each of which comprises of 5 questions. 

Examples of test questions follow so challenge yourself – could you do them?

  1. Jack multiplies a number by 2 and gets 60 as his answer.  However, he should have divided the number by 2 to get the correct answer. 

What is the correct answer?

  1. Julian has a map of Wellington with a scale of 1 centimetre to 5 kilometres.  The runway at Wellington Airport is 2 kilometres long.

How long is the runway on the map? 

  1. Amber’s Mum gave her a bag of sweets for her birthday.  She kindly gave half of the sweets to her brother Boris. 

However, half of these were jelly babies which Boris didn’t like so he gave them to his friend Cliff. Of these, half were green which Cliff didn’t like so he gave them back to Amber. Amber now has 30 sweets.  How many sweets were in the bag at the start?

  1. Starting with a 5-digit number we can make two 6-digit numbers by placing the digit 2 at the beginning or at the end.

If the 6-digit number with 2 at the end is three times the 6-digit number with the 2 at the beginning, find the original 5-digit number.
