The path followed by the Sun is called the ecliptic, and any constellation within the ecliptic is called a “zodiac constellation”. You may be familiar with these as the symbol of your ‘star sign’ or horoscope identity. The word “zodiac” comes from Greek, meaning “circle of animals” and each of the twelve (except Libra, the scales) is represented by an animal. Year 8 Science students are required to search for an image of their zodiac sign and recreate the constellation using black paper and pin-holes. Use my Delicious links at right to start. If you have completed this task, you can search for your 2010 horoscope, and we will try to guess which prediction is true for each student in the class.
What is the difference between astrology and astronomy?
Have astrologers contributed to the science of astronomy?
Year 6/7 students will be creating a children’s story book to teach Mrs. Lee’s prep/1 class about Forces. You will use the on-line program “StoryJumper”, which allows you to add scenes, props, text and a cover to an on-line story book. Make sure your story includes one or more of the following forces: Gravity, Bouyancy, Friction, Surface tension, Magnetic forces, Muscular Forces, Static Electricity or Lift. Here are some examples of stories I have written and illustrated to demonstrate:
“Gravity and the Baby Bird” by Britt Gow
“Platypus Forces” by Britt Gow
You will need to sign up to “StoryJumper” and activate your account using your school email address. You can access your school email account at any time by going to webmail – make sure you have this link book-marked, so you can get to your email quickly and easily.

This week the Year 8 Science class will submit their 60-second science videos to be entered into the national competition. Each of the videos submitted have been uploaded to TeacherTube and can be viewed by clicking on the links below. The next topic is Space – stars, comets and asteroids in our solar system.
Rachel and Kirsten’s “How to make a Rainbow” video
Luke’s “How does a Wind Turbine Work?” Video
Jess’s video about “Oil Spills and Wildlife”
Josh and Cody’s “How a Star is Born” video
Georgia and Maddy’s “Phases of the Moon” video
Year 6/7 students will complete their “Forces” project – a poster or video about the actions of forces. The best of these videos have also been uploaded to TeacherTube and can be viewed by clicking on the links below. The next topic is Electricity. Students will learn what is important about electric circuits, how to make a switch and then construct a simple torch from basic materials (cardboard tube, wire, paperclips, globe, aluminium foil and tape.)

This week Year 7 students start a unit of work on Forces, including magnetic forces, gravity, friction, surface tension and bouyancy. While I am in Melbourne with the Year 11 work experience students, you will watch the Clickview video “Forces and Gravity” and do a short quiz. You will read the relevant chapter from the text book and discuss the activity questions. When I return to school we will do some experiments to investigate the properties of magnets, friction of different shoe types and forces with water.
This week in Year 7 Science we will be looking at Forces – conducting experiments using contact forces (friction, bouyancy and surface tension) and non-contact forces (gravity, magnetism and electr-static forces). In Year 8 Science we will be studying Simple Machines – inclined planes, levers, the wheel and axle, pulleys and gears. One of the best sites to find resources for these units of work is Science-Class-net. There are hundreds of activities, demonstrations, experiments, graphic organisers, quizzes and slideshows about all science topics. I am very grateful to Mr. Poarch, a retired science teacher, for sharing all his wonderful resources collected over a lifetime of teaching and making them accessible on the internet.
