Science Fair, Science in Class.....

We have had a fantastic week (so much so that I needed  the weekend to recover and catch up!). We are preparing for our Science Fair projects. All students have been given a little booklet and a timeline, as well as one being emailed home. If you need another, just let me know. The students are coming up with some interesting topics to investigate too!

This week we have been looking at water quality and how we could filter water on the off-chance we were stuck somewhere and needed to do so. We discussed what types of materials might filter water if we were out in the bush somewhere and needed to drink. We made a list of items such as grass, sand, stones, charcoal, gravel, bark chips or leaves. Each student had a 2 litre empty soft drink bottles, and they had to cut the end off. With very little help from me, they had to plan and carry out their own investigation. It was great to see them talking to each other, comparing their layers in their bottles. The outcomes were even more fascinating! We lined up the filtered water and checked and compared results and discussed why they may be so different - great discussions and even better ideas! Nate had the clearest (let's not confuse clean and clear!) water. We decided to put the water back through the filters to see if we could clear it up even more.
