Buddies





This year we have gone over to the Junior side to be with our buddies. When we are there we do their spelling testing, and when they have finished we do a fun game before we have to leave. This year I have had two buddies Ted, and Harrison. I am with Harrison at the moment and I will soon be with Ted when Harrison's buddy comes back from England. The things that I like about buddies are: we get to go over the road and interact with the Junior side more, we don't have to work in that time, and just to see everyone happy.

What is the Water Cycle


Have you ever wondered what the water cycle is?
The water cycle or hydrologic cycle is a continuous process where water evaporates, travels into the air and becomes part of a cloud, then falls down to earth as precipitation. It then evaporates again. This repeats again and again in a never-ending cycle. Water keeps moving and changing from a solid to a liquid to a gas, over and over again.
Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the rivers, lakes or oceans and rises into the air. Transpiration is just the same but with plants.
Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is when water returns to the Earth's surface within the water cycle. Condensation is the opposite of evaporation.
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the part in the water cycle which provides for the delivery of water to the Earth. Most precipitation falls as rain.
Accumulation of the precipitation is the final stage of the water cycle before it starts all over again. It accumulates back into lakes, rivers, and oceans. If it ends up on land with no source of water near it will soak into the earth and become ground water that plants and animals use.
The water cycle has four main parts to it: evaporation,transpiration, condensation, precipitation and accumulation. The water cycle is very important for humans, animals and plants because without the water cycle none of these living things wouldn’t be here today.

What is the Carbon Cycle


The carbon cycle is a continues cycle like all other cycles on earth.
Carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table. Carbon is what all living creatures breath out. If all humans died the carbon cycle would still continue. 
Carbon is stored in trees, plants, water, animals and human bodies. Carbon is released when trees rot and die, when people breathe out, when wood burns and when animals die carbon is released as they decay into the soil. Carbon can also be released when there is a volcanic eruption.
Humans can get rid of carbon in there bodies by breathing out, and dying its just the same with animals. Plants can get rid of there carbon by dying, decomposing and catching on fire.
When a tree catches on fire all the carbon in the wood releases and rises in to the atmosphere. If you set a table on fire all the carbon will come out and float into the air.
In conclusion we are cutting down all the trees which releases more carbon into the atmosphere which is unhealthy for the planet. We need to stop and think before we kill our planet. We need the trees to breath.
