Holiday update
You will produce a report of your first experiment.
You will look at Solutes, Solvents and Solutions and how Salt pulls water molecules together.

Periodic Table
Review you Major Projects. You are to conduct an experiment in the Next 10 weeks and make a scientific conclusion. You need to make a hypothesis and scientifically test it with controls.
Problem topics at this stage are:
"Are we alone in the Universe?" and
"Territorial marking by Dogs"
In your books
Go to http://www.periodictable.com/ and for Groups 1,2,17 and 18

- list the elements and note colour, metal etc
- draw the 1913 style shell structure
- note the valency of the group
Google"Methane Jmol" this will give a 3D picture methane.
In your books draw this molecule, write its formula.
Google "Jmol Periodic Table" In your book as many things as you can about the relative sizes of elements.
This is an online Acid Base Lab http://phet.colorado.edu/simulations/sims.php?sim=pH_Scale
Write as many observations as you can about acid, bases and different liquids.
To learn more about chemical reations use this simulation.

Thursday Lesson
For your Major Project you have to plan and conduct and experiment in the next 10 Weeks. This period I will review your Moodle submissions, for a realistic area of investigation, a hypothesis that can be tested, and a plan to conduct the experiment.
Some examples of areas of investigation that are unsuitable for a Year 10 Project.
"Are we alone in the Universe?" - as of yet there is no experiment with control to test this
"Scent marking of Dog's Territory" - there is equipment to conduct the study and control.
Use www.periodictable.com to write in your book other elements in the Group 1 (H,Li, K...)
What can you say about these elements. Draw the shell stucture of Group 1 (One electron in the outershell).
Repeat for Group 2 (Be, Mg.....)
Repeat for Group 17 (DET group 7)
Repeat for Group 18
look at Methane a compound (Google "Jmol methane")
Run the simulation http://phet.colorado.edu/simulations/sims.php?sim=pH_Scale
In your book write as much information as you can about pH scale
What the numbers mean, what are the acid and base molecules?

About Me
- drhill
- I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
