Water Science

Today we did a water experiment with ice and salt.  We got balls of ice in a bowl and then our teacher came around the tables with dye to put on the ice.  After we got the dye she came around with salt and we got to sprinkle it on the ice.  When we sprinkled the salt on the ice it started to crack, the dye helped us see the cracks.  We waited a bit until we got to go outside to crack the ice.  After we got outside it was time to crack them.  Each team went at different times.  Our group was last.  When we went we threw the ice up into the air and let it smash to the ground.  The bigger ones smashed more as the weight is heavier.  Because of this there was more force as it was falling.  Here is a picture.

Water Cycle Experiment

On Friday last week we did a water filtering experiment.  In our lesson we learnt about the water cycle and how water gets filtered.  We got told that it takes six hours to clean water!  After we learnt about this we each got into partners and it was time for the experiment.  For the experiment there was a bucket of dirty and non-filtered water.  With that water we used different ingredients to filter it and make it cleaner.  The ingredient we had to use were cotton balls, paper towels, bark and sand.  Not every ingredient filtered it properly though.  When my partner and I finished using the ingredients we chose our own amount of the ingredients we could use to make it as clean as we could.  Me and my partner chose cotton balls and paper towels and it worked!  Here is what ours looks like. 

Science in a Van

On Friday last week Science in a Van came to visit our school.  They taught us about the periodic table and showed us some experiments. My favourite was the cloud in a bottle experiment because it was cool to see the cloud come out of the bottle. Here are some photos.

Science Roadshow

Last week on Thursday the year 5 and 6 students of Good Shepherd School went to Edendale Primary School to experience the Science Roadshow! We learnt so much about ice and fire, the human body and other things that are related to science. We enjoyed watching the hosts do fascinating experiments like dropping an 8 ball into the metal stick with a hoop attached to it, before they dipped it into the liquid nitrogen the ball could thread through the hoop, but after they dipped the stick into the liquid nitrogen the ball couldn’t fit! 

We had a lot of fun, and recommend that everyone goes to the Science Roadshow if they get a chance.
