**Year 7 Science Homework 2013** //Click on the test tube to access the Year 7 Science Resources. // This page is a homework diary in case you are not sure what homework you have for Science. The most recent work is at the top of the page.

More importantly, it tells you what has been covered in class so you can catch up if you are absent from school for some reason. You need to be responsible for organising to photocopy notes you miss, as well as spending time to complete the work you have missed in order to make sure you are familiar with all the material covered in class.

We reviewed what we had learnt earlier in the week about wheels and axles then went on to learn about how using pulleys allows us to lift heavy objects. We also talked about gears and how the gears on our bike work to give us greater speed or as a force multiplier to make it easier to pedal up a hill. We watched a BrainPOP on pulleys and another on gears.
 * <span style="font-family: Georgia,serif; font-size: 17px;">Homework: **<span style="font-family: Georgia,serif; font-size: 17px;">Finish filling in last two pages of fill the gap notes which summarise what we learnt about gears on bicycles and how to calculate gear ratios. The PowerPoint these notes are based on is in the Resources section of this wiki or the same information was provided on the BrainPOP about gears. To rewatch the BrainPOPs we could go to http://brainpop.com and enter the username: ecwbrainpop and the password: ecwbrainpop then search for the topic you are interested in.

We then did a worksheet to see how well we could identify the effort, load and fulcrum so we could identify different types of levers. We learnt about when wheels were probably invented and how a wheel and axle is a special kind of lever. Watched a BrainPOP on wheels as well to make sure we understood how a wheel and axle system can work as a force multiplier.

We then had a look at some plant adaptations by comparing a normal flowering plant, a cactus and seaweed and discussing the importance of particular features in terms of helping these plants survive in their particular habitat. We also listened to a great song by Mr Parr called the Ecosystems Song to remind us of some of the key definitions for this topic.
