9 Aluminium Science

It is now only $5, what a bargain! Take your money to the office, and return the permission note to me with your receipt.

Good news. The Reptiles Alive show will be coming to WHS on Tuesday 29/11! Snakes, crocodiles, turtles, etc. It will cost $6. I’ll get a permission note to you next week.

Our class excursion is still in the ideas stage. Post some ideas for where we could go.

Congradualations on your achievements in the yearly exam! Hopefully you all put in your 100% and are feeling proud of your results. Well done.

Just two more topics to go (ecosystems & technology) till Year 9 is finished.

Dont forget to do your homework for tommorow; water cycle questions.

I’m slightly disapointed by the behaviour of some students during today’s lessons. Lack of focus during the morning lesson caused much of the confusion you experienced in the afternoon lesson. I’ll try to make my high expectations clearer in the future, but I wont be lowering them

Overall I thought it was a success. We will have a debreifing/conclusion in the next lesson.

I am happy you are enthusiastic about the blog, but it is a place of learning and I expect you to treat it with the same respect that you give other such places. This means not posting comments which are off topic and especially not offensive. Please use your well developed common sense.

If you havn’t yet posted your results please do so ASAP.

Yesterday (26/10) we looked at the abundance and diversity of flora and fuana around Wyong River by counting the number of each organism within a quadrant (1m x 1m).

We need to colate all that information into one overall view of the environment around river.

Each group is to submit their table of information as a comment to this post.

On Wednesday (27/10) we collected water from the Wyong River. This morning (28/10) we analysed that water using a stream watch kit, looking at among other things, disovled oxygen (DO), temperature, pH, total disolved salt (TDS), and turbidity.

Each group should have recorded the results of their experiements into the site data sheet during this mornings class. Some sections will still need completing. The Bureau of Meterology may be a useful resource.

We will now collate all that information to get an overall picture of the health of the river. Each group is to submit the information from their site data sheet.

Do this by reproducing your site data sheet in a comment to this post.
