An extension to our commitment to Waterwise Schools is to look at protecting our water sources in WA. Recently Claire Hammersley from Murdoch University’s Environmental Assessment and Management came to St Emilie’s to present an incursion to the Year 6 students about aquatic weeds, in particular Amazon Frogbit.
Here are a few photos of the incursion. The students learned that Amazon Frogbit was recently declared as a ‘weed’ It was originally brought into WA as an aquarium plant but unfortunately has ended up taking over our waterways, depriving our native species of nutrients and oxygen.
The students learned about the different types of aquatic weeds and their habitats in a waterway.
The students had the opportunity to observe and investigate Amazon Frogbit and a native aquatic plant called Duck Weed.
Claire showed small groups of students the ‘catchment model’. The catchment model demonstrates how water travels on the landscape and shows how water pollution impacts the whole catchment and environment.
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.
This week we celebrated National Science Week with Mrs Cogger during Science. Mrs Cogger held the Brain Break quiz for the year 6 students. The students worked in teams of 3 to answer ten Science quiz questions. Mrs Cogger had plenty of prizes to give away all donated by National Science Week.
Our winners with 9/10 were Sienna, Connor and Chanel. They each received a NSW cap.
Second place was Emelia, Meilee and Isabellle. These students received a bookmark and pen.
There were several teams on equal third place.
Mrs Cogger wished to share the National Science Week fun with the teachers. So each morning she emailed out one quiz question. The teachers had to inbox the correct answer. Here are our happy winners.
There were several other National Science Week winners throughout the week. Here are some more happy winners.
This morning the Devereux brothers and and the Backus children met with Mrs Cogger to work in St Emilie’s Community Veggie Garden. Today we had some seed potatoes to plant. These were left over from our donation of seed potatoes from WA Potatoes Seed Potatoes for Schools project. We had been waiting for these last few potatoes to start ‘chitting’. Mrs Devereux also brought along a few of her Royal Blue potatoes that were ready to be planted.
First of all we had to weed the garden bed.
Here we are ‘armed and ready’ with our garden tools.
Then we had to dig a hole to plant our potato.
We are still looking to fill the veggie garden roster with volunteers so if you would like to meet on Friday 17th August at 8am, then please let Mrs Cogger know. Mrs Cogger would like to thank the Devereux and Backus families for volunteering this morning.
Mrs Cogger is delighted to announce that three of our students have been recognised for their fabulous Science designs in the ‘Celebration of Science’ logo competition. This a wonderful way for St Emilie’s to be acknowledged during National Science Week which commences this Sunday.
Our three award winners are
Ellani Limnios 1G
Kieran Ng 4B
Samara D’Souza 6B
The winning entries will be displayed at the Community Science Expo and the winners will also receive a prize. Prizes will be presented to the Logo Competition winners by the City of Canning Mayor at the welcome ceremony which starts at 10am on Sunday 19th August at CREEC.
We hope many of you will be able to attend this ‘free’ event sponsored by
Here are a few of our students entries. As you can see we have a lot of artistic flair and talent in the school!
