Look what we can see with our Digital Microscope

Mrs Hayman bought a digital microscope with some money donated by our hard working PTA.  We can use it all by ourselves.
Here are some of the things we looked at and took photos of.
It made us remember our learning about molecules from term 1.  We couldn't see individual molecules with this microscope, but we did see a lot more detail.

Massage Circle

At the end of reading we sometimes do a massage circle. We end it by leaning forward and hugging the person in front because everyone needs hugs. Then we lean back. It is fun!

Why is the sea salty?

First we watched a video clip and found that the sea is salty because minerals and salts from rocks wash into the sea. Over time due to the water cycle the concentration of salt in the sea gets stronger.
We boiled some salty water in a fry pan to see how this might work... 




We could see the salt that was left behind due to evaporation.

Super Science Friday

We are investigating why sea water is salty. We are also looking at concepts such as floating and sinking and density.

Our experiment was predicting if an egg would sink or float in fresh and then salt water.   We discovered that the egg sunk in fresh water and floated in salt. We discussed why. Some ideas included
The salt pushes the egg up.
The egg is lighter in salt water. 
Then we mixed salt water and carefully added freshwater over the back of a spoon. We predicted what would happen if we added an egg. The children predicted it would float sink.  And it did. The egg floated in the middle. Try it at home. The water must be very salty - about 6 table spoons per cup. 


Congratulations Madi

We presented Madi with her ribbon and certificate for 3 years as an animal handler for Ag Day.

Ag Day Animal Handlers

Congratulations to all our animal handlers. We have Madi and her calf, Emily, Fetcher, Blake and sister Kendall, and Maya with their lambs. 

Earthquake Drill

Today Glenbervie School held an earthquake drill to support the nation-wide "Shakedown" earthquake practice. 

Cricket coaching

Today we had the first of three cricket coaching skills. It was heaps of fun learning to bat and how to catch the ball correctly. Look at us. Do we look like real cricket players? Can't wait for next Wednesday.

Can we clean the water?

We made some filters to try and clean some dirty water.
Our first filter had big rocks, then little rocks, then sand.




We tested our filter with water mixed with dirt, bark, dish washing liquid and oil.
We compared our dirty water with the filtered water and although it was a little cleaner it was still very dirty.  It ran through the filter very quickly.

We then built a second filter - this time we used cotton balls, then stones and then sand.  It took quite a while for anything to happen.  Our video shows this clearly but you have to tip your head sideways because that's how it uploaded.





We then compared the unfiltered water with our two filtered examples.  The cotton ball filter definitely worked the best.  It took much longer for the dirty water to filter through and you could see all the dirt being trapped in the cotton wool.  We talked about how the roots of plants work like filters and help absorb all the things in the water, cleaning it before it goes into the stream.






Class Garden

Our garden is looking great but Olivia is not keen on us making a salad to share.

Super Science Friday - Cloud in a Bowl

We made a model of a cloud in a bowl using shaving foam.


Next we added some drop of blue food colouring to represent water molecules inside a cloud.  The water vapour cools higher up and condenses to form clouds.


As we added more drops they simulated water molecules banging together and forming water droplets.  When the droplets are big enough they fall (precipitate) from the cloud.





We had fun watching the blue rain fall from our cloud.
Try and make your own cloud at home.
