This week the students had a visit from Megan Brown from Waterwise Schools. Megan gave presentations to the students on a variety of Waterwise topics.
Megan explained about the important work of the Water Corporation and it’s role to provide clean and healthy water to Western Australians.
Megan showed us water ‘before’ it goes to the treatment plant.
And we compared the water to ‘cleaned’ water.
Megan told us how the dams used to provide Perth with enough drinking water but because of our drying climate we now have to source other water resources.
We learned how there is limestone in the ground around Perth. Limestone ‘holds’ water.
Megan showed us this fantastic model of the water cycle and we could see how the water soaks into the ground below.
We learned about the desalination process.
To conclude we learned that our drinking water comes from three sources – dam, ground and desalination.
The Year 5 students had an interesting presentation about how Aboriginal people valued and sourced water and the strategies that they used to locate sources.
The Year 6 students completed a quiz using Keepads.
We learned about the desalination process – how the water is processed using
- ultra filtration
- reverse osmosis and
- ultra violet light
This is the unit used in the reverse osmosis process.
The water goes through four stages before it is pumped into our water supply.
The Year 3 students participated in a drama activity about the water cycle.
The focus in the Year 4 session was to learn how leaves use and transport water. The students had the opportunity to use their Rotary microscopes.
We thank Megan from Waterwise Schools for sharing her Waterwise knowledge with us. The presentations were most informative.
