Lights! Camera! Action!

Today, we had a real life scenario for physics.    We had to recreate an action movie car crash scene.  My group got scenario #1.  We had one car going one way and another, faster car, going perpendicular do it so they would go boom! If they don't collide, then we fail.  Our slow car took 17:19secs to go 2meters.  The faster car was took 10:30secs per two meters.  One car always had to be on the table and we could only use on car at a time.  The only time we could have both cars going at the same time was when we were doing it for real.  My group had to start the slow car, which was positioned two meters away from the point of impact, and at 12seconds, we had to start the faster car.  Our group had the best crash!  Mr. Battaglia said that some babies died in that crash!


Where does the bad light goes?

Title

Today we had a white board discussion.  Today is like the first time I got a chance to talk because of this new rule of raising our hands to talk.  I asked a question to this one kid who was talking about the flat lines on the graph.  He said maybe the first was traveling sideways.  Since velocity also involves direction, I asked what it would look like on a motion map and a velocity vs. time graph.  He didn't really answer but that's okay.  We had a quiz... I mean fiesta...today.  I'm not very confident in my answer.  When finding the slope, I counted like how if the y axis intervals went up by 5s, rise over run be a number divisable by  5 over what ever number.  So if the point was 3 points up and 2 points over, I would have gotten 15/2.  I don't know if it is right, now, but at the time it seemed like it.

Cartwheels for a Cause

Hola bloggers,
today we finished up a lab we started 5days ago.  We have to recreate numerous position and velocity graphs using our bodies, a motion detector, and Dora the Explorer.  Once we actually started using our equipment right, we saw that if the slope of the line was positive (moving away from the reference point (reference point was the motion detector)), it was above x axis line.  If it was a negative slope, then it was below the x axis line and moving towards the reference point. 
Last class I was wondering what it would look like if someone did a cartwheel.  Mr. B let us test it out since we finished the lab early.  He asked us to predict what it would look like on the graph.  I said that it would probably look like if someone was walking except a little more wavering (of the line) because I was the one doing the cartwheel and I can barely walk in a straight line let alone do a motion where I put my hands on the SLIPPERY floor and flip my legs over.  My prediction was right (YAY), and me and another girl at my table each did 2 cartwheels, one going towards the motion detector and one moving away from it.  The lines on the graph were really...wobbly I guess.  I don't have a smart phone (yet, I'm getting one soon!!!!) and wouldn't be able to take a picture to put on here, but I totally would if I could.  The lines all looked the same except the lines we spaced out...a lot.  It most likely has to do with I'm like...7inch taller and she was wearing jeans.  Anyway, we had to make motion graphs for the lab.  I didn't get it at first but after doing a few of them, I totally understood it.  I'm like the motion graph MASTER now!  Until next time,...wait I almost forgot the joke...that would have disappointed you, wouldn't it have?

Blog Buddies

Heyyyyyyyyyyyyyyyyyyy, Today in 1A Physics, we got assigned two people to read our blogs and comment on them.  We also went over our hw from Monday.  My group did question #1.  I was happy to draw on the white boards because I'm a dork like that :).   Jessie and Marty demonstrated what the graph said.  I thought a possible situation for it could be two people left from their houses to go for a bike ride.  Ones house is farther away from the other which is why one started in the origin and the other was above it, closer to the final destination (as my group came up with).  We discussed whether speed=velocity.  We concluded it didn't because velocity also includes distance or direction. Question #2, was basically the same thing but there was another graph in addition to the first one.  Line A had a negative slope in the 2nd graph.  One person thought that it meant that the cyclist went out for a ride (graph 1) then they took a break.  In graph 2, A and B turned back home and B went back out for a better workout. I thought it meant the same except in graph 2, B kept going without turning back but their isn't really a way to determine that.

PANDIFLY

Bonjour mon amies,

Today in science, we took a quiz on conversions.  I got 1 or 2 wrong...plus the 4 @ the bottom that I didn't read the instructions and answered them wrong, so beware and ALWAYS read the instructions.  On the back we had to draw a panda mixed with a butterfly,  (I call it a Pandifly) I think it looked pretty good... :/...maybe.  I have a question for all you people out there reading this...( Mr.Battaglia and possibly Shirley), how many fruit flies would fill up a school bus? The closet estimation of an answer you can possibly get...

What did the receiver say to the radio wave? Ouch! That megahertz.

Now I'm going to work on some speeches for debate (Meet on Thursday @ Stevenson) and then write a letter for french.  Its like a rough draft of what we will be sending to our french pen pals.

Scientific Notation

Hello Blogger World,
   Today in science,  we got cookie sale sheets (yum). And we also made a conversion table and did some stuff with that. i.e. 24Km =_____mi.  

24Km*1mi/1.6093Km. You would cross out the Km's and end up with 24/1.6093 and that ='s 14.91 mi.  

Ok so scientific notation.  9000000 is the same thing as 900000 * 10.  Which is the same as 90000 * 10^ 2. And so on until you end up with 9 * 10 ^6. 10^6 is the same as 10*10*10*10*10*10.  9260000= 9.26 *10^6. .000006 = 6*10^-6.  

Old science teachers never die. They just don't react.

Let's Fiesta!

Hey. Today we discussed the differences between inverse and indirect.  Indirect means not direct.  Inverse means opposite of pretty much. i.e. x*2= y/2 and is also a form of indirect.  Direct means when x goes up, y goes up.  Proportional means when x goes up and so does y but at a constant rate.  (sorry about the confusion on monday). Today we also took a fiesta***.  I forgot to write whether it was direct or indirect or inverse and I realized it the second I sat down.  At the end of the hour I told my teacher and he let me add it on.






*** fiesta means quiz

First Attempt

Hey all you bloggers,
today in science, we got into two groups, (I was in group 2), and made two circles, an inner one and an outer one.  Group 1 was in the middle first while group 2 was on TodaysMeet talking about the discussion.
Group 1 was talking about #11, #13 (and #14) of our Scientific Method Worksheet 2: Proportional Reasoning worksheet.

#11: Let y= a/(bx^2).  In each case listed below, describe how y will change. Explain each response.
a. Double a, keeping b and x constant.
    
b. Double b, keeping a and x constant.

c. Double x, keeping a and b constant.

My question was basically how to answer this question.  Apparently I was over thinking it because most of the people just plugged in numbers and write an explanation like y will increase.  What I'm going to do next time, even though I got the same answers as group 1, is plug in multiple sets of numbers just to double or triple check my work.

 # 13 and14 were directly and inversely proportions. The group brought up the differences between directly and inversely proportions and direct and inverse relationship, as did my group, and I thought I would look them up for anyone else out there who doesn't understand it either. 

• directly proportional: a relationship where a # increases or decreases together with another # with the same ratio - toolingu.com 

• inversely proportional: a relationship where a # either increases as another decreases or decreases while another increases - toolingu.com

• direct relationship: a relationship between 2 #s or variables where an increase or decrease in one # or variable causes the same change to occur in the 2nd -investorwords.com

•  inverse relationship: a relationship between 2 #s or variables in which an increase in the value of one # or variable results in a decrease in the value of the other # variable or the other way around -investorwords.com

 So my group, group 2, only about 3 people talked because #12 was so similar to #11.  Those 3 people went insanely fast and only confused the rest of us, then they went back and explained them more.  The girl sitting next to me, when the convo. was nearly done, she asked a question about #15 and we answered it but then she stopped discussing #15 and went back to #12 and restarted that subject and everyone was even more confused by that part so Mr. B stopped the circle. 

Anyway, about the problem we talked about how everyone, to solve the problem, plugged in #s for the variables.  We noticed that everyone used small and easy #s like 2 and 3.  Trying to solve the problem the quickest and easiest way using a minimal amount of effort is human nature! 1s and 0s will mess up the data and decimals, and negatives aren't as easy to use.  We had someone in the group plug in decimals and negative numbers and we still got the same result but it took a lot longer.

And finally, the moment you have all been waiting for..... the joke!!!!!!!!!
  
 An ion meets his atom friend on the street and says he's lost an electron. "Are you sure?" asks the atom. The ion replies, "I'm positive."

Until Wednesday, (hopefully),

Pilot 9/26/13

 Hey bloggers, I am going to be adding a new post every week for my 1A science class.  I am going to try to include the following:

• white board circles 
• a lab
• hw
• what I liked about the class and what I didn't
• give a mini lesson on what we learned so i can show i understand it and help other people that don't
• questions about things I didn't understand in class, then look up the answers and add it on here to help people that have the same questions

And finally...............

• SCIENCE RELATED JOKES

Until next time,
