Bridge Building

We have been learning about forces and how they help shape the sort of bridges that we build. 

We learned that there are three main types of bridge design; beam, truss and suspension.  

Using this knowledge we designed and built our own bridges.  

Miss Fletcher set the challenge that our bridges had to be 30 cm long and strong enough to hold an object.  

In my group there was Mikayla and Olivia.  

We used egg cartons cardboard ice block sticks paper towels to build our bridge.  Here is a photo of our truss bridge.  

What I like best about our bridge is how we drew the road.  

Volume and Capacity

This week we learnt about Volume and Capacity.

Speeches

For the last two weeks we have been working on writing speeches. 

My topic was on Kauri Dieback.

We had to present them in front of our class. 

I think I need to ad more eye contact

Here is my speech. Why we need to stop Kauri Dieback

Have you ever thought about the impact that Kauri dieback is having on our forests?  Well I have and it is a terrible disease. Kauri dieback is a disease that can spread from tree to tree in only 7 sleeps. I believe we need to stop this terrible disease from spreading and here is why?

Firstly the Kauri dieback disease can spread quickly through Kauri tree forests by the touch of a footprint. This disease kills the trees. People need to stop and clean their shoes and gear before entering walking tracks to stop the disease reaching the trees.

Secondly Kauri dieback can have a huge impact on forests. If Kauri dieback spreads to Tane Mahuta in the Waipoua forest, many other trees could be destroyed because Tane Mahuta’s roots hold up lots of trees. It would be so sad to see this happen to such an important part of New Zealand and Maori History.

Finally we need stop Kauri dieback because Kauri trees are native to New Zealand and native birds live in them. If the disease kills off all our Kauri trees there will be no homes for our wonderful native birds.

Kauris are endangered because of kauri dieback but if everyone helps out I believe we can stop it from spreading. That is why we need to stop Kauri Dieback.
