unit 11

Electricity and Magnetism

In this lab i enjoyed a lot learning about something that has the potential to be dangerous.  This was seen in the one day where we had some presentations from Mr. Adams that he said were dangerous and that we shouldn't do it at home.  Some of this stuff included shooting a magnetic bar, and levitating a copper tube.

My favorite lab from this was the thing that we did on the computer.  I enjoyed virtually messing around with resistors, light bulbs, and switches.  It made it easier to understand how certain parts of an electrical system work.

Some vocab words from this unit are:

Parallel system

Magnetism

Transistor

Ohms

Resister

Unit 10

Waves and sound

I really enjoyed this chapter because i could relate it to music.  I can now somewhat visualize the waves of sound when using and amp, singing, or even playing drums. One interesting thing that we did that i found to be hard to understand was the tuning fork exercises.  How it only worked at a certain height showed how sensitive sound can be.

My favorite lab from this unit was The slinky lab.  I enjoyed doing this but it was hard to focus with my funny and outgoing team mates.

Some vocab words from this unit are:

Node
Anti- Node
longitudinal , transverse, standing wave

Unit 9

Light Behavior


My favorite thing that we did in this unit was messing around with the laser and putting it through different substances.  For example putting it through glass is much different than putting it through plastic of water.

My favorite experiment from this chapter is the electromagnetic spectrum.

Some key words from this chapter are:

Reflection
Refraction
Divergent
Convergent
