Happy New Year and Welcome Back!!

​

If you have not taken the 2nd Quarter Common Assessment, you

need to get it done TODAY!

​

If you missed any work before break, I also need it TODAY!

​

We are starting a new chapter today, guided reading 3.1 "Describing Motion and Force".  It will be due on Tuesday. 

 

Here is a copy of the worksheet.

Here are a couple of videos about the physics of sky diving.  Pay attention to the arrows (vectors) that represent the forces involved.  Gravity is a force that pulls everything to Earth at a rate of 9.8m/sec/sec and all objects in free-fall are acted on by a force of air resistance or drag which is a type of fluid friction.

​

Here is a myth busters video demonstrating the sky dive from a plane

without a parachute as in the "Indiana Jones and the Temple of Doom".

Here is Felix Baumgartner's jump from the stratosphere.  Yes, this

is real!! https://www.youtube.com/watch?v=E9oKEJ1pXPw

​

3.1 guided reading is due today.  

​

I am doing a demo called Newton's Beads today.  You will need your comp book for the demo today.

Here is what we are doing.  I have a long strand of beads in a container that I will dump out.  I will dump them out from 3 different heights and time how long it takes from the time that the first bead hits the floor until the last bead hits the floor.  We will do 3 trials from each height.  The first height will be from a seated position.  The second height will be from a standing position. The last height will be standing on the chair. 

Before we begin, we will hypothesize what will happen to the time it takes for all of the beads to hit the floor as the height changes.  This will be recorded in your comp book on a table.

It should look something like this:

​

​

​

​

Analyze your results.  What happened to the speeds?  Why?  Was your hypothesis supported? How?  The write-up will be due on Wednesday.

​

If you miss the demo, watch this video below.  You will have to hypothesize what you think will happen if you drop the same strand of beads from three different heights.  You must have 3 reasons why you think that will happen.

​

Your Newton's Beads demo write-up is due.  I will want to stamp your composition notebook.  This must be written in the notebook, not on a piece of paper.

​

We will have a packet on "Describing and Measuring Motion".  There is a brief reading selection and questions that follow.  I am sorry, but I do not have a pdf of this packet.  There will be a quiz over this on Thursday.

​

Here is a video on relative motion.  It might help you to understand the crow dropping a ball question on the back page of today's worksheet.

THURSDAY 1/9/2020

​

The "Describing and Measuring Motion" is due.  There will be a quick 10 point T/F quiz over this packet.

​

There is a worksheet over reference points for homework.  If you class has a popcorn reward party tomorrow, your class will also get the "snail speed and velocity" packet.  I am sorry but I do not have a pdf of these worksheets.

​

​

​

Friday 1/10/2020

​

6th and 7th hours will be enjoying a reward party.  Do not forget that all work will be due on Monday.  

​

Frame of Reference worksheet is due.  Two snail worksheets for homework.  On one you must calculate speed and velocity (distance / time).  On the other you are calculating acceleration ({final speed - initial speed} / time).  I am sorry but I do not have a pdf for these worksheets.
