The Water Cycle Explanation Writing

The Water Cycle 

I am learning to inform my audience through an explanation.

By Peter

When you take a drink, do you ever stop to wonder where water came from or how it came to be? Maybe you drank water that cavemen drank millions of years ago? Maybe it could be from a plant! Maybe it came from the water cycle! The definition of a cycle is a series of events or steps that are repeated over and over. The water cycle is really simple anyone could understand it (except babies). 97 percent of water on earth is salt water, leaving the other 3 percent fresh water. The only problem is with freshwater, is that we can only drink 1 percent of the freshwater because either the water is groundwater or it’s ice. The water cycle consists of the three main stages, evaporation, condensation and precipitation. When precipitation ends, the water cycle will restart all over again. The first stage is evaporation.

When you look at your clothes on the clothesline, it may seem wet, but after a while, all the water’s gone off the clothes! This is because the sun evaporated the water off the clothes. It’s the same with the water cycle. The sun will heat up the water and the atoms in the water will move super fast, then the water steams up. And when all the steam is gone, it already has turned into vapour, which you cannot see. The sun will evaporate the water from the plant, but that has another name called transpiration. The heat from the sun will transpirate the water from the plant into steam and into vapor. The vapour now leads us to the next step of the water cycle, condensation.

The next step leading on from evaporation is condensation. An example of condensation is a hot shower. Since the water from the shower is already hot, the hot water will evaporate itself and when it meets the surface of the cold mirror, the mirror will become blurry. This also happens with the water cycle. When the water vapour has risen into the atmosphere, it reaches its dew point and starts to cool down and turn into very tiny water droplets. As the tiny water droplets fill the cloud, the cloud grows darker. The dark clouds leads us to the last step of the water cycle, precipitation.

The last step of the water cycle is precipitation. As the cloud grows darker, it fills up to its maximum limit of water droplets, causing it to rain. Rain state of matter being a liquid.. It can also fall as snow or hail this is its solid form, mist and fog in gas form. Rain that falls to earth that collects together forming a body of water is called collection. But if water falls onto soil, it may seep into the soil and become groundwater. And water that falls onto land, could take another route to a source of water. This is called surface runoff. And if the water falls into a moving stream, that is called streamflow.

In conclusion, the water cycle is something that we cannot live without. Every step is needed for the water cycle, or the water cycle will cease to exist. Evaporation turns and heats the water into steam, condensation, turning the vapour into clouds, and precipitation water falling back onto the ground or a water source. We should take more care of our water and should not pollute the water or else we wouldn’t have water.

Watercare

Water, water everywhere! On Friday of week 6, we were lucky to have Sally from Watercare come to teach us more about the water. We did a drama activity and experiments. Firstly we examined the process that water goes through to become drinkable water in our households. Our drama was based on the process that the water goes through to be cleaned. We were the water going through each stage. We had so much fun as we ventured around the school. Once we learnt how water is cleaned we then had to try and clean the dirty water ourselves. We had to create a filter system in partners. We had to do four different tests for our experiments. We experimented with a range of filters to try and test which filter system was the best.

Cross Country

Cross Country

Good Shepherd School had been busy training for cross country this term and finally the day arrived. In week 6 we all arrived at school in our running gear and had our house colours painted onto us. We were eager and ready to go and win house point. Overall the race was long and required a lot of stamina, but we were prepared. Here are some pictures from our races.

Samoan Language Week

This week was Samoan Language Week. In Room 6 we learnt a lot about Samoa and the Samoan culture. We watched Cultural Hub clips about the Samoan alphabet, animals and body parts. Did you know that the Samoan alphabet has only 17 letters? We had experts teaching us greetings and phrases.
Our experts were Matila, Remy and Rosa.

Science in a Van

A few days ago, we had science in a van. During "Science in a van", they did some cool experiments.
They balanced a mop on only two fingers using physics. Then another guy did another physics experiment. He picked up a table with a bottle with a cloth underneath it. Then he removed the cloth  underneath it and the bottle didn't move at all. They did more experiments, but the last experiment was my favourite. They got some dry ice and sealed it tight in a container. And for a moment, it didn't do anything... but popped off when you least expected it.

Balloon Experiments

Yesterday we did some science experiments. We blew some balloons and tested the pressure. The balloons were red, yellow and blue. The blue was the one with the most air pressure because it was so big and all the pressure was getting all pushed and it was really packed. The red was the least because it was so small. We did another experiment, where someone blew the balloon and put it underwater in a bucket. When he unleashed it, it went back to it's original size, then water came splashing out of the bucket. 

Growth Mindset Studies

In term 1 we learnt about growth mindset.
We studied about famous people like, Marie Curie,
Thomas Edison and Martin Luther King ,JR. Our group chose to study about Albert Einstein.

This is mine. I chose to study about Albert Einstein because he discovered the famous equation e=mc2.
