More About Pulleys and The Extra Hand

Lots of machines have pulleys in them for example a cage that pulls you across a river.                           David

You use pulleys when you are sailing. It makes it easier to pull the sails up. You also use pulleys on cranes to lift up heavy objects like big containers. Also on flying foxes you connect the pulley to the wire. And with flags you use the pulley to raise the flag.                      Ben

You can find pulleys on cranes, garbage trucks with claws, big boats, sail boats, ski lifts, drawbridges, flag poles and bikes.              Margeaux

Today we had a big argument about where the weight goes when you pull the weight up with the pulley. First Ben said half the weight goes to the beam. It does, so he was right. The beam acts like another hand.                        Patrick

We learned that the beam supported half of the weight and our hands supported the other half of the weight.                    Josh

The weight will be half the weight that it actually is. This is because the beam is acting like another person so it is halving the weight between you and the beam.   Margeaux

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.  

By Margeaux 

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.

Lifting With A Pulley

First my class saw Ruby using scales with a metal lathe plate hanging on the bottom of the scales then her face turned red.

Suddenly Mrs Bryant said, “You can put it down now”.

Then Ruby had a turn with the pulley. Mrs Bryant asked, “Is that easier?” Ruby replied, “Yes”.

Suddenly Mrs Bryant told me to have a go.                   David

Pulleys make it easier to lift things into the air. They are useful for lifting weights and heavy things. Today in class we were lifting a metal lathe plate with scales and a rope with a pulley to see which one was harder to lift. We found that it was harder with the scales. To get the lathe plate the same height as it was with the scales you need to pull the rope two times higher. Lawson

Lifting with the pulley is a lot easier than lifting with the scales. Because the scales just tell you the weight and the pulley is helping you to lift what ever you’re lifting. When you’re lifting the pulley lift it two times higher than the weight moves.                                                                Aria

Pulleys make it easier to pull things up. You have to pull it two times higher. Jonty

Bat On

The Hobbits Reading group created this poem in response to a poem they read called Kick Off.

 Bat On
The team wants to be the ball flying through the sky,
The ball wants to be the bat whacking sixes,
The bat wants to be the pads protecting the batsman’s body,
The pad wants to be the bowler bowling the ball at the wickets,
The bowler wants to be the umpire putting out the finger,
The umpire wants to be the fielder catching the ball,
The fielders want to be the wickets getting smacked down,
The wickets want to be the crowd cheering out at the end of the game,
The crowd wants to be the team, holding the World Cup ...

An Exciting Day
