Science Week Five

Homework; we are almost beginning the first internal assessment (and credits) for the year and your homework is to be completing the research task One, on fossil fuels. You will have received this in class but is you have misplaced it you can access it from the link list on the right hand side of this page. There is also research task two on Biofuels. Both these tasks are to be completed before assessment which is taking place in two weeks time and you are welcome to begin the second task now.

Advantages and Disadvantages of Biofuels

Advantages and Disadvantages of Biofuels: "Primary Advantages and Disadvantages of Biofuels

No fuel source is completely positive or completely negative. Consumers need to weigh the pros and cons of biofuels to determine whether they feel comfortable with this emerging resource as an alternative to traditional fuels."

Homework

Currently you homework is to be completing the first research task which was handed out this week. You should do this in your exercise book so it can be ticked off as part of the assessment. If you need another copy of the assignment you can down load it from the links on the right hand side of this page or click here.

We have begun the year with a topic that looks at the implications of using carbon compounds as fuels. So far we have met a family of hydrocarbons known as the alkanes. These are the compounds found in petrol, diesel and LPG and are currently being used around the world in enormous quantities.

In our practical work we've been comparing complete and incomplete combustion using the laboratory Bunsen burners.

 

We have also attempted to calculate the amount of energy produced from a candle flame.
