Roller Coasters!

You built and tested your roller coasters during block this week. I'll have winners, pictures, and video later. Have a great Thanksgiving.

Roller Coaster Investigation

Today is your first day to work on your roller coaster. Most people just experimented with loops and heights and will actually build the things during their block day this week.

For today, I just need this info from you to help me buy supplies:

Build A Roller Coaster Intro

Today was yours to finish Energy II and to start the Build a Roller Coaster lab. You will have both periods next week to complete the roller coaster; we will test them in the last 20-30 minutes of your block period next week.

Power

Really short notes about power on bellwork:

The rest of the period we worked on Energy II (conceptual, honors). This is due tomorrow, and you will have some time to work on it tomorrow.

Everyone: Pulley Lab

Today first period is continuing work on their pulley lab and all other periods are starting it. It is due on Thursday for everyone.

Pulley Lab

Conceptual: Pulley Lab

Today we started work on the Pulley Lab. We will continue working on this tomorrow and it is due Thursday.

Honors: Efficiency

Today's only new thing appeared in #3 on bellwork:

Homework tonight is Machines II. The hard copy has a typo on the fourth line: change d_out from 10 m to 1 m.

Honors: Machines

Homework is Machines I.

Conceptual: Efficiency

We spent bellwork doing a few problems like the ones on last night's homework, then added one new thing: efficiency. Homework for the weekend is Machines II. The fourth line on the hard copy you were given has a typo and you will not be graded on those answers.

Honors: Energy Conservation Practice

Today we practiced an energy conservation application: the roller coaster! Your homework is Roller Coaster Practice (below). I also passed out missing assignment reports.

Homework front:

Homework back:

Conceptual: Machines

Homework is Machines I.

Honors: Conservation of Energy Verification Lab

Today we're doing a verification lab about the conservation of energy. The bellwork was a bit of a warm up and the lab can be found here.

Conceptual: Energy Conservation Practice

Today we practiced an energy conservation application: the roller coaster! Your homework is Roller Coaster Practice (below). I also passed out missing assignment reports.

Everyone: Conservation of Energy

Notes today really were just explaining the bellwork:

Then we played with a pendulum. Homework is Concept-Development 8-2:

Everyone: Work

Today we are talking about work with all classes. Bellwork:

Notes:


For Honors, we also added that W = Fdcos(theta), where (theta) is the angle between the force and distance vecotrs.

Homework tonight is Ranking Tasks: Work, which looks like this:

Honors: Energy

Today we are trying something that we've never done before: bookwork!

I actually don't know how to teach with these things because I've never had them. So we'll just see how it goes and mop up any misunderstandings later. Your homework is Energy I (see below).

Conceptual: Conservation of Energy Lab

Today we're trying out a new lab. I've never done this one before, so we'll see how it goes. First, some bellwork to get warmed up:

An electronic copy of the lab is here, and the setup looks like this:

It is due on Thursday.

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.

Conceptual: Energy Practice

Today we did a bellwork that basically summarizes the reading from next week. Then we finished Energy I. No new homework tonight.

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.

Conceptual: Energy Continued

Today we're continuing the assignment from yesterday (click here for details). Please turn in Energy I on Monday.
