Erosion Challenge- Alex Jack Callum

Last Monday we had an erosion challenge where we had to build a block house to put on a sand hill. Then we had to defend the house from weathering, buckets of water, with bark, sticks and other materials. Here are some photos of our groups creation-

Our final creation had a rock buried in the hill and bark buried around the hill.

After a second bucket of water, our house was demolished.

Overall, our group came second. Something we could improve on is making the house sit on the flat bit of the rock. Some things we did well were making supports under the house and putting bits of bark around our hill, making the water run straight off the hill, keeping the sand from eroding. In the end we were proud of our defences from the weather and the design of our house. By Callum and Rowan

DESTROYED IN MINUTES!!!

We start building.

We add a moat.

We look proudly at our finished project.

We look at other groups ideas.

We got a sprinkle on our house, it didn't do much. 

A down pour hit our house and made a sink hole.

Overall we were pleased with some of our design ideas but if we did it again we would put some stilts under the house to hold it on the hill. We would also put a channel in the sand to stop the water from damaging the sand around our house.

Destroyed in seconds!

For our erosion challenge we built a Lego block house that looked a bit like a castle, but it looked more like a big square of blocks. We put bark around the outside of our house and a bunch of sticks crossed over diagonally underneath our house so it would hold the house up. Unfortunately our house didn't stay in place.

This is our house after the sprinkle.

This is what our house looked like after the event...knocked off the top of the hill.

If we did this challenge again this is what we would do differently: 1) Make the sand hill wider so the house would stay on the top.
2) We would use more pinecones to surround the house or use a stick tee pee to hold the house in place.
3) We stuck sticks into the hill to make it strong but we would bigger sticks and have them on the bottom of the house.

We had lots of fun doing this challenge in the sandpit and we learnt alot about erosion.

Jack, Charlie and Max are proud of their results in the junior athletics.
Great to see you wearing your sunhats.



Fundraising

In Room 2, we have been fundraising for solar lights and have raised $71 in total. We have raised the money by having a colouring competition, a jelly bean in the jar challenge, with the prize being all the jelly beans and the jar, Halloween mufti, and a Halloween cupcake sale. We also got a $100 donation from the Waihola Woman's Institute. 

Our blog

Hi Room 2, let's get this blog going again!  Claudia took some photos of our athletics today.  They are saved in a folder called athletics 13.  Can someone put some up for us, with a write up?  Our athletics day is now November 7th - 3 weeks away.  Keep practising!

Solar power vs Wind power

In room 2 we have been comparing the positive and negative points of wind power and solar power as alternative power sources. We researched many questions that we had about each power source. We also interviewed Bob Lloyd a physics lecturer from the university and asked him a lot of our questions. After comparing all of our information we found that solar power is a better option for our area, it would not cost as much, need less to maintain, they are more energy efficient and has a longer warrantee. We investigated different solar power options for around the school, such as a solar sprinkler, a solar fountain, a scarecrow and solar lights for the path to the hall down the steps. Room 2 decided that the solar powered lights would be the best option. We have researched a range of solar lights from websites of local companies and selected 3 based that we felt would work. We would love your feedback on which one you think would be best for us to purchase from the options below.

OPTION 1: The Warehouse

OPTION 2: Mitre 10 Mega

 

OPTION 3: Mitre 10 Mega

 

 

TO VOTE FOR YOUR FAVORITE PLEASE MAKE A COMMENT AND SAY WHICH OPTION 1, 2 or 3 YOU LIKE BEST and WHY. Thank you from Room 2
