Science

The aim was to blow our balloon up using yeast.a small paper funnel, a small plastic bottle and a balloon.
=== You needed: 1 tablespoon of yeast, half a teaspoon of sugar, 15mls of warm water, a small paper funnel, a small plastic bottle and a balloon. === === Steps: Using the small paper funnel, put yeast, sugar and water into the bottom of your bottle. Then place the lid on top and give the bottle a decent shake. Then replace the lid with your balloon. Wait for your balloon to blow up and then you have your very own bread balloon. ===

===We are also having a science fair. Everyone has their own investigation and we have come up with them ourselves. I am doing my science fair on bread. I want to find out what type of bread (brown, wholemeal and white) is most cooked after being in the toaster for 5 minutes.n ===

=**Science Extension:** = ===Recently, I have been involved in a Science Extension at Kuranui College. 2 - 3 children from each school in the South Wairarapa (Martinborough, Greytown, Carterton and Gladstone) went. From Greytown School Alice and I went. (Alice is one of my besties) === === We were taught by 2 of Kuranui's science teachers named Miss Wishe and Mr Tavernor (I hope that is how you spell their names) and we did heaps of different experiments with them. === === On the first day with Miss Wishe, we went over which metals react with certain acids. We also did an experiment to find out which snack food gave off the most energy. The end result was that the banana chip gave off more energy, because when we set it alight with fire and held it under a test tube, the water in the test tube's heat changed rapidly from about 25 degrees to about 85 degrees. The other snack foods were a ready salted chip, a twistie chip, some popcorn and a peanut. The peanut let off a reasonable amount of energy but wasn't hot enough to beat the banana chip!!!!!!!! :) === === On the second day with Mr Tavernor, we worked out how fast the water reacts with the acid. We changed the amount of water and acid that went into each test pot. We wrote a cross on a piece of paper and placed it underneath the test pot and stopped our timer when we couldn't see the cross as when the water reacts to the acid, the water goes very murky.. When there was 10mls of water and 5mls of acid, it only took about 35 - 40 seconds for the cross to disappear so it was by far the fastest!!!!! :) === === I really enjoyed the Science Extension as it was fun, I met new people and I got to try out lots of experiments. Alice and I had plenty of laughs like when she dropped the banana chip on the ground and made scorch marks!!!! :) :) :) ===

Term 3:  I am sorry to say (because I enjoy science) that we have not done any science this term.
