Soap Power

Our next bubble experiment was Soap Power.  It was was an experiment where we made a little boat, put it in some water in a bowl, and put dishwashing liquid in the engine.

The result was the boat speeding through the water for a few seconds and then stopping. If you tried it again in the same water, it would just sink. The reason it moved through the water was because the dishwashing liquid would break up the water molecules making the boat move forward. The reason it didn't work the second time was because there was already dishwashing liquid that had broken up the water.

18 Christchurch Schools to Merge

Today we looked at the governments plan to close 13 schools and merge another 18 in the Christchurch area.  As we are a merged school (Dannevirke Hillcrest and Dannevirke North) we looked at the challenges these schools have ahead of them during and after the merge.  Below, in no particular order, are our thoughts;

  1. naming the school
  2. deciding on the site
  3. closing the other schools
  4. deciding on uniforms
  5. merging cultures
  6. making new friends 
  7. bullies
  8. new teachers
  9. distance from home to new school
  10. adjusting to a new school
  11. money
  12. reemploying staff
  13. creating mottos
  14. deciding on what resources to keep or get rid of
  15. hiring builders
  16. deciding on logos/emblems
  17. what curriculum to use
  18. class sizes
  19. voting on a BOT
  20. celebrating special days/important events to specific schools
Have you been involved in a merger - school or business?  What challenges did you face or what other challenges do you think these schools are going to come across

Although we were faced with many challenges early on we think our merged school is now terrific!!  We wish these Christchurch schools the best of luck.

Bubble Duet

Knowing that bubbles are fill of air we wanted to find out how bubbles affect each other.  Daniel's diagram shows the experiment we carried out so we could observe related bubbles.

Below are photos of us carrying out the experience to observe how bubbles relate to one another.

We know that bubbles that are related affect each other.  One bubble will suck the air out of the other bubble therefore one bubble gets smaller whereas the other bubble gets bigger.Posted by Picasa

How Bubbles Form

For science this term we are relating the observed chemical and physical properties of bubbles.  To achieve this we are working together to build on prior experiences when sharing and examining new knowledge.

After participating in the experiment we discussed our observations on what bubbles are and how they form.  Below is Tyson's diagram showing the experiment.

Below are photos of us blowing bubbles and then making observations on what bubbles are.

We know that bubbles are globs of air or gas inside a hollow liquid ball.  The detergent forms are skin to trap the air.

Number Bonds to 1000

We have been looking at a strategy to solve number bonds this week. Conscious used the iPad and the app "Show Me' to explain how to solve these type of problems.

Should Christchurch get a new stadium

We have looked at the pros and cons of Christchurch getting a new stadium.  We then used the pros and cons to draw a personal opinion on Christchurch getting a new stadium.

                    PROS                                                                   CONS
Wowed                                                    No economic argument for having a stadium
Beautiful                                                  Large investment for peak events that come around very rarely
City benefits by                                       Black holes for massive amounts of public money
$1m for every major event                       Rate payers can't afford them
World class attraction                           
Luxury for a city experiencing hardship  

I think Christchurch should build a stadium but not now.  First they should spend the money on rebuilding residential areas.
I think they should not build a new stadium because Christchurch will be low on money and they wouldn't have any money for the people.
I think they shouldn't rebuild the stadium because there is more stuff to worry about but maybe they should rebuild it in the future.

I don't think they should build a stadium.  They still need to rebuild Christchurch and still have to repair the 25% of houses that still don't have plumbing and power.

I think they should build the stadium but after 95% of the houses are rebuilt.

I think they should recreate the AMI stadium because the Crusaders are the only Super 15 team that doesn't have a home stadium.
