Science Fair Orewa College (1)

Science Fair is something we do not know at schools in Germany, but it is very common in Intermediate and High Schools here in New Zealand.

This is what students usually do: Pick a topic of your choice, then prepare a paper following a particular structure, which could be like

hypothesis >> background information >> equipment >> experiment >> data and graphs  >> con-clusion.

Once written down you print out your paper and glue each page to a board (see pictures below). They are then presented to a teachers’ board, they vote for the best papers which then will participate in a competition with other schools!

YES, you can certainly learn a lot from these posters, at least from a few! So let’s see what you could learn …

This is how all the posters were lined up....

Question 1: "Which substance best enhances the longevity of cut flowers?" WOW, that was certainly I was interested in, what a great topic! And the results was a big surprise,… is it:
  1. Sugar
  2. Vinegar
  3. Coffee water
It’s sugar!! So next time, when you give your love a bunch of flowers by and add a little sachet of sugar! I am wondering, if we should ask the flower shop around the corner, if they should or could sell sugar in the future as well ...

Add sugar to flowers ?

Question 2: This is certainly a question which is essential when trying to survive a major disaster: "Does M&Ms or Pebbles melt faster?" As far as I recall I think it was Pebbles melting faster. So if a disaster hits you during a hot summer night you better had bought M&Ms to keep everybody happy.

So what melts faster?


More hot topics and results in two days ….
