How Does It Happen?


Bucket Experiment

On Tuesday Hoiho class did Jacob's Wonder Brick. The Wonder was "How does water stay in a bucket when you swing it around?" First we got some people to swing the bucket around with the water in it.

Patrick and Aria got a bit wet because the bucket hit their leg when they were swinging it around.

The water stays in the bucket because the water swinging around in a circle gets a force, which makes the water want to fly outwards. If you swing the bucket around fast enough this force will be greater than the force of gravity so it wont spill.

The amazing water and bucket trick!

On Tuesday, Hoiho went outside to do a "bucket" experiment. We filled the bucket up about half way with water, and if you spin the bucket around your head so your arm just touches your ear, the water will not fall out! 


The water stayed in the bucket because of centrifugal force. The bucket is what stops the water from flying outwards. Without the centrifugal force, you would expect for the water to fall out of the bucket because of gravity!
(Phew, thank goodness for centrifugal force!) But if you fill it to the brim, some of the water will come out while you are getting it up to speed!

Dome Strength


We brainstormed strong 3D shapes on the whiteboard . We said that an arch was a strong shape, then we talked about where your weight would go if we stood on an arch bridge. We had a lot of ideas about where our weight would go but we found out that it went down the curved sides towards the ground.Then we demonstrated with our arms how strong a dome is with Jonty and Mrs Bryant pushing the top of our hands down. It was fun experimenting with domes.

On Wednesday 4th Hoiho class did a science experiment. What we did is we got four empty three quarter eggshells. We put two eggshells close together at one end and two at the other end in a rectangle shape. Then we started to put blocks on.

Some people thought that the eggshells wouldn’t hold three blocks. We stacked the third block on the empty 3/4 eggshells. Finn, Jacob, David
We put on the 4th block and there was a loud CRACK! Everyone yelled and I said "That was close". And one eggshell was cracked now. By Patrick 
Then we placed the tenth block on top of the ninth block. And the eggs didn’t break. Caleb
On the 14th block we heard a crack in an eggshell and it collapsed like the twin towers. By Margeaux
On Thursday we were writing like scientists about doing a forces experiment. First we did the title then the materials. After that we did the hypothesis. Then we did the procedures which took a while. Last of all we did the conclusion.

Garden Fundraiser Meal

On Friday we had a fundraising lunch to raise money for a small and poor school in Vanuatu. We grew some of the food ourselves! We grew HUGE cauliflower and broccoli! Here are some of the things we ate: grated carrots, pesto, wraps, hummus, broccoli stalks, stir fry, cauliflower cake, apples, fejoas , bread chips, onion dip and heaps more. Making the lunch was lots of fun, and it was worth spending our time preparing it because it was very tasty.
