Quater 3 Blog #7

I hope that I did really well on my test and now that we are moving on to the rockets I hope that I can raise my grade a little.  Since I am doing this blog late I know that I did really well on my test.  I also know that I only got 1 point off so that was a 27/28.  I think that the review sheet really helped my study for the exam.  I hope that there will be a little bit more of grades that will be imputed into the grade book so I can raise my grade.  I think that for my rocket project I will be able to reach the 10 seconds that I need to do to get an a.

This week in physics we were learning about the multimeter and how to measure amps and volts.  To measure volts you need to attatch the two ends to the end of the resistor.  To measure amps you need to create a break in the circut.  I also realized that amps can be measured in multiamps and regular amps.  The lab that we had done really helped me to understand the concepts that we were trying to be taught.  I also think that the review sheet will help me a lot for the test.  For this up comming test I think that I will do well on the multiple choice portion.  I feel that I need to work on the math and equation section of the test.

This week in Physics we learned about ohms and how there is resistance in current systems.  We also learned how energy will always choose the path of the least resistance.  After we learned how to draw schematic diagrams and how to solve different equations.  For parallel systems we learned about how the amps split in parallel systems while they stay the same though circits that are wired in series.  While circuts are wired in parallel the amps split between each path that is created by the wire.  In parallel circuts the voltages stay constant while voltages in the series will change as it goes though each resistor.

This week in physics we are just learning all of the differnt equations for the unit.  We learned ohms law and why it works.  We also started to touch on what parallel and seirers wiring is.  We are also learning about ampameters and how the work and how to use them.  We are also learning all of the different setting and how to measure resistance and voltage.  With the lab we learned that wring in serires will make the voltage drops across the enire system stay the same.  When wired in series the amps will be devied throughout the entire system and then the light bulbs may be dimmer when more are added in the system

Energy Savings

I asked my parents about saving our energy bill, my dad told me that it wont make much of a differnce because we have seven people in our house and he has just added more photovoltaic panels on top of our roof.  The bill that I brought to class was from september and since then he said that we have added one more set of panels to our roof.  My dad told me that our energy bill is arround eighty dollars.  I think that it isn't that bad considering my brother runs his ac all night, we have 4 refridgerators, and all of our rooms have ac.  In my house we also use solar water and propane fore our stoves and dryer.  My dad tries to consierve as much energy as he can because he says that the energy prices are just going to rise continuesly.

Blogpost Quarter 3 #2

This week in physics we mainly reviewed the lesson that we were learning.  I don't think that I really prepared well for upcoming test that is on tuesday.  I think that the equations will be the easy part of the test while the unit concepts are going to be challenging for me.  On the PA I had a hard time on problems 9 and 10.  I was wondering how do you find h, m, q, and g while it doesn't give you any numbers to start off with.  Although I feel that the free body diagram is pretty easy to draw the challenging part is knowing where there is an electrical force.

Quarter 3 #1

This week in Physics we are learning about positive and negative charges.  When doing the lab I realized that when applying friction to something it becomes charged.  Weather it becomes a postitive or negative we do not know.  I was wondering if there was a way to tell what the tapes were charged while doing the lab.  Me and Joe tried to put it to a postitive end of a battery to see if there would an attraction or a repelling effect on the tape.  It turned out that it didn't matter weather the positive end or the negative end of the battery, the tape was attracted to both sides.  I also learned that when touching the tape it regains a neutral charge because our bodies take away or give that extra electron to bring the charge of the tape back to neutral.
