Everyone: Study Guide/Work Day

These are the things you need to accomplish today and tomorrow:

1. Turn in Build a Roller Coaster
2. Turn in missing assignments (I passed out missing assignment reports)
3. Make corrections
4. Work on Study Guide (conceptual, honors)

Your test is on Friday.

Study Guide answers below:

Honors: Momentum Practice

Today we simply practiced some momentum problems before we move on to energy tomorrow. Momentum III (front here, back is below bellwork) is due the next time I see you.

Honors: 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: 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.

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.

Conceptual: Momentum

Today we introduced momentum! Homework is Momentum I.

Honors: Momentum/Rotational Motion/Gravity Study Guide

I was going to try to squeeze in a lab before the next unit...but then almost no one turned in Momentum III and those that did left most of it blank. I also found out that I'll be gone on Friday and I didn't want you doing a lab while I'm gone. So today (and tomorrow and Friday) are going to be work days. In addition to completing Momentum III like you were supposed to, you can work on the study guide for our second test, which will be Monday.

Study Guide

AIMS Days

I will see half of you Monday and half of you Tuesday due to the AIMS testing schedule. Conceptual classes, you have work time to prepare for your test on Wednesday. Honors classes, you will be learning a little about angular momentum (see below).

Honors: Momentum III

I wasn't sure how many of you would be here today, so we just worked on some practice problems in the form of Momentum III.

Conceptual: Study Guide Answers

Today we played a bit with angular momentum. The answers to the study guide I gave out yesterday are below.

Honors: Collisions

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

Elastic Collision I
Elastic Collision II
Inelastic Collision

Tony tried to film some more today...they are a bit shaky.

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

Homework is Concept-Development 7-1.

Conceptual: Momentum Study Guide

 Unit 9 Study Guide

Honors: Recoil

Guns recoil when fired to conserve the total momentum. Here is a video we watched that shows recoil fairly dramatically. No homework tonight.

Conceptual: Momentum Practice

Today we are catching up and doing some practice problems. We'll probably have a test next Wednesday, after Rodeo Break.
