Hi Hyrum,

I was really impressed with the way your environment group put together your presentation for the airport mural.  It was great to see you look at your first draft of your mural, pick out what worked, what didn't work, and make changes accordingly.  Refining is what can make good things even better!
It was great to see you aspiring to new projects during passion time.  I hope that your stone carving comes together, and that mum has a blast working on it with you!

Air Pollution

Today at Enrich we looked at the air pollution. Wellington is the least polluted city in the world at the moment. The most polluted city is in Iran. It is called Avhas. It is the most polluted city in the world. I definitely wouldn't want to live there. If you don't know what it looks like have a look at these up the top. In most of these places you probably won't even be able to see the stars at night. You should be very happy that we have fresh air and clean water.

Environment

Today day at Enrich we worked on our environment projects. We organize the presentation. We also did a good copy of the mural that we are hopefully doing at the airport. We sorted where we think it should go and it is very blank. This is what it looks like.

Later on after morning tea we talked about water pollution. We watched a video about the water pollution and here's a link to it.  http://www.youtube.com/watch?v=-YAoyTsyM7M. It was saddening  seeing whats happening to the sea life. We found out that tortoises and turtles are now the most endangered animal groups. I hope that after you watch this you will think about you having fresh water because lots of other don't.

Fibonacci maths 2

Today at Enrich we did the high interest station again we went though and looked at other way of how the Fibonacci sequence connects to nature. Like, a rabbits family tree and a cows family tree. Up the top there is a family tree of a rabbit. You can see that the dots go 1, 1, 2, 3 and the rest of the ones that are on there. It was great learning about the Fibonacci sequence. I will probably see how far I can get at home on a piece of paper. There is also a picture of a Fibonacci spiral.  The size of the boxes are the Fibonacci sequence.  It connects to so many things in nature!

Fibonacci numbers

Today at Enrich for math we did Fibonacci numbers. They are a sequence of numbers where you add the two number before the number for example 0 and one make 1. Here's the first 100 numbers:

 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811 29514229 832040 1346269 2178309, 3524578, 5702887, 9227465, 14930352, 24157817, 39088169, 63245986, 102334155, 165580141, 267914296, 433494437, 1134903170, 1836311903, 2971215073, 4807526976, 7778742049, 12586269025, 20365011074, 32951280099, 53316291173, 86267571272, 139583862445, 225851433717, 365435296162, 591286729879, 956722026041, 1548008755920, 2504730781961, 4052739537881, 6557470319842, 10610209857723, 17167680177565, 27777890035288, 44945570212853, 72723460248141, 117669030460994, 190392490709135, 308061521170129,

It get's very high numbers in the first hundred numbers. It was very fun this morning and here's a picture of Fibonacci. The largest Fibonacci number has 465 digits

We explored how a Honey bee's family tree was like the Fibonacci sequence.

Electricity circuts

We used 12 batteries in this one 

We used 12 batteries 

                                                               I think this we used 6 batteries

Today for science we made light bulbs. We used pencil leads, a jar, pie tin, positive and negative wires, eight D size batteries and tape. First we got out the batteries and taped them into twos. We attached the  wires and tried a whole lot of different leads. The first one we used was the hard kind. It exploded. The next was soft and one lit up and broke. We kept experimenting and I think it was when we used twelve batteries to power a 4B lead. Here's some pictures of most of the attempts.

Today at Enrich I did chemistry with Jenni. We made elephant toothpaste. We had to put rubber gloves on to protect our skin and hands. We had to because it had hydrogen peroxide in it. We added food colouring and yeast to make it rise. This was what it looked like after we poured the yeast into it up above. Mine was the second biggest. Kavarn's was the biggest
