Perry Peak News

Beached Whales!

News Flash!

There was a large commotion today at the

coast near the town of Perry‘s Peak. A large

group of whales became stranded on the beach.

This presented a huge problem for sun bathers

and nature enthusiasts. The bigger problem is

how to rescue them before they perish.

The onlookers tried everything they could

think of from pushing the whales into the water

with tractors to bribing the whales with food.

Nothing has worked so far. The town’s mayor is

hoping that a solution can be found soon!

Real World Solutions:

Levers & Pulleys Project How can we use our knowledge of levers and pulleys to solve real world problems?

For this project, you will be organizing into “companies” to solve real-life problems

involving the use of levers or pulleys. You will begin by answering the following four

guiding questions:

• What will we lift?

• How heavy is it?

• How high will we need to lift it?

• What is the best way to lift the load? (lever or pulley)

This first stage may involve some research. For

example, if the challenge you have chosen involves

moving a whale, you might need to look up the

average weight of a whale.

The next step will be to create a scenario in which

your load must be moved and to where. This would

be the “real life problem” aspect of the assignment.

You will answer the following guiding questions:

• Why does my load need to be lifted?

• Who needs the load lifted?

• Where does my load need to go?

• What is my timeline for lifting the load?

You will need to create a newspaper ad or feature

story to introduce the scenario you are solving. For

example, if your problem involves moving a piano,

you may create a “help wanted ad” for a person

requesting help from a local company. On the

other hand, you might be using a feature story in a

newspaper about a beached whale needing lifted

from your local beach.

Following this step, you will need to determine the

dynamics of your company. You will need to

answer the following questions:

• What is the company’s name?

• What kind of work does your company do?

• What is your company’s slogan?

• What role(s) will each member (or employee)

play in the company?

• What is your plan for accomplishing the

project and managing your time so that you

meet the required deadlines?

You will eventually create a company poster advertising your company

including your company name, slogan, and type of work that you do.

Next, you will need to do the math behind the assignment. All students in the

group must work together on this portion of the assignment. Work must be shown

in the boxes provided on the proposal sheet. You will be applying skills and

knowledge that you have acquired throughout our science module. Be sure to

determine which simple machine is the BEST choice for completing the job! Use

the following as a guide:

Levers:

1. Determine the weight of the object being moved.

2. Determine the class of lever that you will use for this assignment.

3. Determine the location of the effort and load that will give you the greatest

advantage.

4. Determine the distance from the fulcrum to the load.

5. Determine the distance from the fulcrum to the effort.

6. Calculate the Newtons needed to lift the load using the formula.

Load x Distance Fulcrum to Load = Effort x Distance Fulcrum to Effort

Ex: 220g x 20cm = e x 10cm

4400 = 10e

4400 = 10e

10 10

440g = e

4.4 Newtons = effort

7. Determine the price you are going to charge per Newton of effort to lift the

load.

8. Determine the cost involved in building the lever (*may require some research).

Add this cost in to your price.

9. Calculate the final price you will charge for your work. Is it a reasonable

price? Do adjustments need to be made?

Pulleys:

1. Determine the weight of the

object being moved (load).

2. Determine the distance that

your object needs to be

moved.

3. Determine the type of pulley

that you will use to accomplish

this.

4. Determine the number of rope

arms you will need if you are

using a compound pulley.

Keep in mind that one person

must be able to lift the weight of the load when you are done designing

your pulley system.

5. Determine the amount of rope that you need to move the required

distance.

Length of Rope = Distance load needs to move x # of Rope Arms used on your pulley

Ex: 10 m x 3 rope arms = 30 meters of rope

6. Determine the amount of effort it will take to lift the load.

Effort = Load ( lbs/g/kg) / # of Ropes

Ex: 12 lbs. / 2 ropes = 6 lbs. that will need to be lifted

7. Calculate the amount of work you will need to do.

Work (Newtons per cm/m/mile) = Force (Effort in Newtons) x Distance (in cm/m/miles)

8. Determine the price you are going to charge for each N per distance of

work.

9. Add in the price of the rope and pulley(s) (*may require some research).

10. Calculate the final price you will charge for your work. Is it reasonable?

Does it need to be adjusted?

Next, you will write up your proposal. This is the overall plan for your project. It will

be submitted to the teacher for approval. Later, it will be used as a “pitch” to

your prospective client.

Project Proposal: Completion Date:

1. What is your overall

scenario or problem?

2. What will you lift?

3. How heavy is the load?

4. How high will you need to

lift the load?

5. What is the best way to lift

the load?

6. Place your calculations in

the box here & draw an

illustration if necessary.

7. What will you charging

your client for this service?

(calculations)

8. What is your company

name & slogan?

9. What tasks will each

member of your group

complete?

6

You will need to complete the following components for this project:

During the final stage of the project, each company will “pitch” their

proposal to convince their clients that their company is the right company

for the job and should be hired for the work. This portion of the project

should include the following:

1. Hang your presentation board in front of the room.

2. Introduce your company and employees.

3. Address the problem that you are being asked to solve.

4. Explain your solution to the problem.

5. Explain your pricing

6. Finish off by telling the “client” why your company is the “right

company” for the job.

� A newspaper ad or feature story to

introduce the problem your client has

� A proposal for the work to be

completed

� A company poster advertising your

name, slogan, and the type of work

that you do

� A company presentation to the class

7

Scoring for this project will be based on the rubrics provided. Each student will receive both a

group score and an individual score for their work and participation in this project.

Please keep in mind the following organizational points:

i. Groups will be chosen by the teacher

ii. Most of the work will be completed in class

iii. Companies will each have a folder that contains their work

iv. Folders will be labeled and left in the classroom (no official papers may leave the room)

v. The assignment and requirements can be accessed online in case you need to view it

from home
