Conceptual: Energy

Today and tomorrow you are reading about energy and completing Energy I. I cannot post the reading here, so you have to get it done during class.

Honors: Recoil

Guns recoil when fired to conserve the total momentum. Here is a video we watched that shows recoil fairly dramatically. Homework tonight is Ranking Tasks: Momentum.

Honors: Save the Egg!

First we did a bellwork about bouncing and watched a couple of videos (here and here) that showed the difference between bouncing and not bouncing.

Later we completed our Save the Egg! activity.

Conceptual: Practice and Angular Momentum

Today we mostly practiced stuff we already knew, either through bellwork or by completing Momentum III (sorry, I have an e-copy of the front side only). We also looked at some "magic tricks" involving angular momentum, but you will not be tested on that.

Honors: Change in Momentum (Impulse)

Homework is Momentum II. Next class you are making and testing a device to save an egg from a drop from the second floor, so bring materials if you want to use something other than pop cans, cotton balls, skinny balloons, and duct tape.

Conceptual: Collisions

Today we talked about the two kinds of collisions. We tried out several collisions on an air track. There are some videos of this demo from over the years on YouTube (thanks to the long-ago-graduated Edgar and Tony):

Elastic Collision I
Elastic Collision II
Inelastic Collision

2012-2013 school year:

Elastic Collision 1
Elastic Collision 2
Elastic Collision 3
Inelastic Collision 1
Inelastic Collision 2
Inelastic Collision 3

Homework is Concept-Development 7-1.

Honors: Momentum

Today we introduced momentum! Homework is Momentum I.

Conceptual: Recoil

Guns recoil when fired to conserve the total momentum. Here is a video we watched that shows recoil fairly dramatically. Homework tonight is Ranking Tasks: Momentum.

Work Day

Because of all the people taking math AIMS, we had a work day today.

Honors: Forces Test

You will have 30-35 minutes at the beginning of the period to work on your study guide and notecard. The last 55 minutes of class you will be taking your test.

Conceptual: Impulse and the Effect of Bouncing

This is all we got written on the board today, but I'm also posting some old notes below it that are more explicit. We also threw eggs at a sheet and made devices to save an egg when dropped from the ceiling. Homework: Momentum II..

Videos of bouncing are here and here.

Honors: Forces Study Guide

Today is your day to work on the study guide for our second test. We also counted stamps today. Next class you will have about 45 minutes to last minute studying, and the last hour will be your test.

Period 4, I have to proctor AIMS on Wednesday, so make sure you email me any questions Tuesday as you will not see me Wednesday. miss.volkening@gmail.com

Study Guide: Forces
Answers:

Conceptual: Momentum

Today we introduced momentum! Homework is Momentum I.

Honors: Tides

Today we talked about tides and black holes. If you missed the notes, the Wikipedia acticle on tides is quite good. For our class, we care about what causes the basic tides, spring tides, and neap tides. You will not be held responsible for all the details in the Wikipeida article...although the whole subject is quite fascinating.

I also found a pretty good video that explains the tides well. You can view it here.

Here is a video we watched of the very dramatic tides in the Bay Of Fundy.

Homework: Tides

Honors: Law of Universal Gravitation

Homework tonight is Universal Gravitation.

Conceptual: Forces Study Guide

Here is your study guide for your second test: Forces Study Guide. Your test is Friday.

Honors: Finding g With Centripetal Force

Today we used centripetal force to verify the acceleration of gravity near Earth's surface. The bellwork is below. Here is the lab.

Conceptual: Law of Universal Gravitation and Tides

Today we talked the Law of Universal Gravitation:

And we practiced a bit with Universal Gravitation.

Then we went over some consequences of the fact that gravity is weaker at larger distances: tides and black holes. If you missed the notes, the Wikipedia acticlte on tides is quite good. For our class, we care about what causes the basic tides, spring tides, and neap tides. You will not be held responsible for all the details in the Wikipedia article...although the whole subject is quite fascinating. 

Here is a video we watched of the very dramatic tides in the Bay Of Fundy.

Here is a video of the amazing Neil DeGrasse Tyson explaining black holes. My pictures are backwards from his explanation - I drew a person diving in, while he talks about a person going in feet first.

Homework: Tides

Honors: Centripetal Force

Today we talked about centripetal force and practiced a problem combining circular motion and friction. Your homework is Circular Motion II.

Conceptual: Work Day

Period 1 gets one more day to turn in missing work and make corrections. Please do so! I will do my best to get those into the gradebook for your quarter 1 grade.

Work Day

The end of the quarter is tomorrow, so today we had our crazy-busy work day. You got a missing assignment report (except period 1 as the system was down - you'll get one tomorrow) and I posted new grades. I cannot guarantee that I'll get all your late work and corrections graded on time to go on the quarter grade, but I will try.

Centrifugal Force

Today we spoke briefly about centrifugal force. We were really killing time on a pep assembly day, however, so we won't be testing on this. No homework.

Conceptual: Centripetal Force

Today we talked about centripetal force and practiced a problem combining circular motion and friction. Your homework is Circular Motion II.

Honors: Rotational/Circular Motion

Bellwork became a sort of notes today:

We went outside to run around in circles to discover the relationship between tangential velocity and radius and tangential velocity and rotational speed.

Homework tonight is Circular Motion I.

Honors: Static Friction Lab

First we walked through Inclined Planes I, which you worked on when I was out last Friday.

Later we completed the Static Friction Lab. It is homework if you didn't finish in class.

Conceptual: Centripetal Force Lab

Today we completed the Centripetal force lab - it is homework if you didn't finish in class. Bellwork set it up:
