electricity

Today in metal technology, we have been learning about electricity. i've learnt that electrons are what power electricity. electrons are the pieces of an atom that are zipping around the shells. I know how voltage runs through out batteries (negative to positive) as well as power (positive to negative). I learnt about cells in batteries and and that they need a flow to keep them going.

Metal technology - Automotive

Automotive

For the last few lessons of Metal technology, my class and i have been learning about automotive and how a petrol and diesel engine works. personally, I prefer an diesel engine. mainly because it cost almost a dollar less than regular petrol however it is not that good on the environment. The difference between a petrol engine and a diesel engine is a petrol engine needs a spark plug to start the vehicle where diesel engines need compressed air to start the vehicle. i'd prefer pwning a manual vehicle, 5 speed to be exact. Reasons being, you can haul heavy stuff or when your stuck, you can get out just by adjusting the transfer case. manual can go faster with the more RPM (revs per minute) which is another reason why i want a manual.

Bridge building

Today in metal technology, our class was split up into 4 groups

and we were told to create a bridge out of Popsicle sticks and a hot glue gun.

at the end of this unit, what ever group held the most kilograms on their bridge would get a prize

of $5 and I happened to be in the winning group. Me and my two teammates,Rome (the guy on the very right) and Vaden ( the guy in the middle with the red hair) are so amazed that we won and it so happened that we beat the school record!!!

Here is a link that takes you to to a result table and proof that we won...
