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.
