Net Forces with Barbie

This unit focuses on the idea of Barbie as she travels through her daily life, experiencing net forces.  Our goal is to keep her as safe as possible.

Friday and Monday!

Task 1:  Designing a bumper for Barbie (this will be tested on Tuesday, 4/3)
Task 2:  The physics of seatbelts (you must design a seat and a harness with 3, 4, or 5 points of security for Wednesday)
Task 3:  Determining mu and mu reflection
Task 3:  Barbie's parachute
Task 4:  Bungie jumping!

Bridge Project on Statics

Go to http://bridgecontest.usma.edu/  and download the software.  Run the install program and decide on your bridge.

Your goal for day one is to get a working bridge, and then minimize costs.

You will receive points for

  • the weight your bridge can hold
  • the design cost of your bridge
  • the aesthetics of your bridge design and its build
  • the agreement in design size between your bridge and your model

When you get a working design, you will need to minimize the costs.  When you think you are done, call me over, and send me a copy of the design file.

Building the model:

You may use straws (a hollow core structure) or a bamboo skewer model.

Build the bridge at a scale that is .5 m = 1 cm.  Both sides will need building, as well as one crosspiece of cardboard and a bottom of sticks

Newton, and the Concept of Force

Finishing up Q3

GPS discussion (I'll be calling you)
Quiz 1, #2, #3, Worksheet 2





Create an outline or motion map for the each of the sections found in these two lessons.   The creation takes the place of notes, so yes, you must EACH do this.

Newton's Law Lesson 1
Newton's Law Lesson 2

Application:   Using what you have learned about vectors, and vector components, as well as the 8 subtopics described in the two lessons above, concentrate on ONE of the sports below and tell me how the sport is connected to the concepts in a poster format.

Baseball
Skateboarding
Racing

Vector Benchmark


As a culture, we have increasingly become reliant on GPS technology.  Farming, map-making, navigation, surveying, and military identification are increasingly connected to this network of satellite locations.

Project:

A.   Explain to me, using a hand-drawn picture, how GPS works.
B. Use Google Maps/Google Earth and find the exact location of five landmarks in the West Delaware District. Create a series of vector representations that tell me how far each landmark is from the old front door of the school.  List the starting GPS coordinate, the final GPS coordinate, the path length/degrees, and the two legs.
C. Check into these location, as well as the school using a GPS receiver or a smartphone software tool. If you choose to use the GPS, you will need to geocache the trip.

Common smartphone tools:
  • Facebook checkin (you would need to friend me)
  • Foursquare (again, friend me)
  • Mapmyride.com
Turn in your completed project by Thursday.  Groups larger than 3 will not be accepted.

Google Earth Trip



Your goal is to take a 6 stop trip around the world, starting and ending someplace in the West Delaware school district.  Along the way, scrapbook, in some way, the important landmarks you find.

Use the path feature of Google earth to help you determine the vector for each, and separate into component legs.   This form  will be helpful.


When we get done, we will write a reflection on what you've found out.  Expect this at the beginning of the class on Tuesday.


Grading is highlighted by the checklist found here

Golf Course Intro to Vectors




Step 1: You, along with one or other designers , will be putting together a 9-hole golf course. The maximum area available for the golf course is a land area that is 1760 yds by 2650 yds (you do not need to use all the land). A lovely creek (not a river) runs through the land, and there are trees on two edges, and a housing development on a third. You will need to have PAR information to do this, but these values are approximate, so you do have some leeway.

For the purpose of this activity, cost is no object, so trees and sand traps can be added at will.

Establish a scale: ___10___ yards = 1 cm is quite common

Draw a detailed sketch of your course using the paper by the meter sticks and hand in. Make sure you have added a compass rose and have marked the scale on your paper. 
Color the course using colored pencils or crayons.

Provide a vector length and heading for the first leg of each hole

Hints: Club houses are often 6000-15000 sq. ft. Houses are often 1800-4000 sq. ft., with the upper range representing a mansion-style home.
If you choose to make a mini-golf course, you have an area that is 100 yds by 500 yds, and must include a clubhouse, a parking lot, 9 holes of golf, and a snack shop On one side of the course must be a go-kart course.

Hint: Google 'golf course design' if you need a sample to get ideas.



Step 2 :
Each person in your group will make a scale drawing of one hole, using a scale of 3 cm = 120 yards, in Google Presentation, Open Office Presents, or Power Point. The scale drawing will be done digitally using Power Point, but three copies of the hole must be handed in. Label the drawing with a hole number, mark the tee with a T, and the hole in a flag. Make sure the compass rose on this drawing matches the orientation of the hole on t he master course. The master course must also be handed in.
