Making hokey pokey - the baking soda has a chemical reaction and makes the sugar go hard

turn the lights on - its converting electricity into light and heat

playing tennis - action reaction, hitting the ball it bounces off the racket

cooking noodles - the boiling water cooks the starch in the noodles and making them soft to eat 

mowing the lawns - pulling the starter cord uses kinetic energy

the fridge - using electrical energy  a heat exchanger to remove the heat

TV - electricity to convert the TV signal into a picture

making banana quick- the quick particles dissolves in the milk

tap - gravity makes the water flow

lighting the gas - the gas burns, heats the water which cooks the 
food

microwave - the microwave energy heats up food by warming the water

putting the jug on - electricity is used to heat an element which  heats the water
  
dishwasher - uses the movement of water (friction) to clean the dishes

computer - electricity gets converted to on and off voltages it goes through logic components 

telephone - sound gets converted to electrical impulses 

Lawnmower - the spark plug creates a spark which ignites the petrol which explodes and drives the piston around

growing vegetables - photosynthesis

compost - food chemically decomposes ( its a chemical reaction )

camera - light goes through a lens and the image is stored 

bread making - the yeast mixed with the warm water and sugar starts to grow and makes the dough rise

Open a coke bottle - causes a sudden difference in pressure and the carbonated water erupts through the bottle making bubbles

burning a candle - the wax burns to release light and heat 

WiFi - the electromagnetic waves carry the signal and data 

stereo - converting electrical impulses into noise

Eating - your body uses the nutrients from the food to power your body

Lightening and Thunder - when 2 cloud masses collide there is electrical discharge

Tides - created by the moons gravitational pull

Day and Night - the earth spinning around on itself as it goes around the sun

Seasons - caused by the angle of the earths axis as it rotates around the sun

boat - it floats by displacing its own weight in water (this is action reaction)

Tongariro Crossing

On Saturday I woke up at 5:30am and got in the car we drove to the shuttle park. James and I found a perfect walking stick.

The shuttle came but it could only take 5 people so we couldn't get on. Finally the second shuttle came it could take 21 people so we got on and I took the stick with me.

When we got to the start of the track, we started to walk and it was nothing like I thought it would be and it was nice an silent. It took an hour to get to the saddle .

We started to think if we were going to climb to the top of Ngauruhoe and we thought we would give it a go and we started; we didn't go very far until mum and I didn't want to go any further but dad and James kept going. We thought we had gone quite far when we got to the top.

We started to go over a long flat part and we stopped and looked at a water pond and had a rest. We started walking again and we started to climb up a slippery part. There was a chain that you could hold on to too help you get up.

We got to the top of the hill.  I wanted to go to the top of tongariro so we started to climb and it was so windy so we came down. We went down a steep rocky face and stopped and had lunch at the edge of the Emerald lakes.

We walked over the last flat and climbed up the hill and saw the Blue lake. I thought it splendiferous.

Finally we were on our way down, we stopped at the Keretahi Hut and had more food and a toilet stop. We saw where the eruption damaged the hut from 2012.

Walking through the forest we seemed to walk for ages and ages before we finally made it back to the car.

There was lots of amazing scenery but it isn't the sort of thing to rush back and do quickly because it is such a long walk.

holiday writing

In the holiday I went horse riding; my horse's name was Cisco. My mum drove us there.

first I got on my horse and waited for the rest of the group, then we got in an order and I were second to last. we walked along the track and when I finished you got to choose to trot or walk. I decided to trot. 

We had family friends there and we were the only people that decided to go faster but one of our family friends wanted to walk because the last time she rode a horse she had a bad experience. So we went off on the track and we started to trot and I thought it was really fun compared to walking. We were trotting and walking on and off. Now we all started to gallop. 

I think that horse riding is really fun and I want to do it again. There is one problem, it is expensive.
