The reading this week that interested me the most was learning information and new facts on ground water, which was put together by 'The Groundwater Foundation'. It was interesting to me because I have recently learnt that groundwater can be used as our water supply and it is the water that is stored under ground. According to 'The Groundwater Foundation' we are using groundwater at quite a fast rate. They have supplied a few tips on what we can do to help protect it. Some of my favourites are:
1. Take shorter showers (this is so easy to do! and we can all help if we stick to it)
2. Get involved in water education :)
They use groundwater in Perth for example, however here in Melbourne the water we use is surface water, which comes from lakes and rivers. Just to get a better idea visually, here is a graph Jenny included in her lecture to show us the distribution of Earth's water supply.

During the lecture we focused solely on water, what a huge topic!
Water is essential to all forms of life on Earth, it is so important and I didn't realise just how much we have of it on Earth. When I look at pictures of our planet and see all this water in oceans, but looking at the statistics is what really makes me open my mind to it. Water actually makes up about 70% of the surface of our planet, how incredible!
One concept that I learnt this week was that water is an amazing solvent. What does this mean? Well water is capable of dissolving a number of substances, making it a great solvent. It actually dissolves more substances than any other liquid ever. As a result of being a fantastic solvent, a lot of the worlds water has salt in it. I took a quick survey of what people think is inside a bubble when water heats up and here were the answers.
Sarah: Air Maddy: Carbon Dioxide
Laurie (Dad): Hot air Hayden: comes from the water. A mixture of air and water
Weirdly enough, the bubbles actually come from the water itself. When liquid boils, it turns into gas. In relation to water that gas is steam. Almost all the gas in the bubbles of boiling water is simply water vapor.
This weeks group presentation in our tutorial was on 'Stories of Cosmology.' The presenters focused on the big stories of Ancient Egyptian and Chinese cosmology. I learnt that cosmology are the stories of the origins of our universe and how it all began. The group mentioned that in Ancient Egyptian cosmology involved God's and the ones I took interest in were called Ra and Maat. Ra was the god of the sun, he had a falcon head and had a sun disc resting on his head. Maat was the goddess of both truth and justice.
In Chinese cosmology one of the points was the story of yin and yang and qi. The yin means ngiht and the yang means day and these are said to be two of the six heavenly qi.

To finish on this weeks reflection I just want to mention some ideas I could use in my future classroom in relation to science experiments involving water. Jenny mentioned these to us and I want to make a note of them because I don't want to forget. I'm super excited about using them one day!
WATER TENSION EXPERIMENT
This involves seeing how many water droplets you can fit on a 5 cent piece until the water bubble bursts. Apparently it fits a lot more water than you would think!

WATER VAPOR EXPERIMENT
Dip your hand in water and create a hand print on the ground to see how fast the print disappears. When you see the water disappearing, this is a visual model of water vapor.
