# Related Rates Project – Calculus

## Timeline

• March 8/11 – Project introduction & initial problem selection
• March 12/13 – In class project work time, come prepared next class for feedback from Mr. Germanis
• March 14/15 – Project Feedback Day. Come prepared next class with a short 2-minute presentation of your work to the class.
• March 18/19 – Paper Projects Due by 2:05pm (or emailed rgermani@fwps.org by 9pm if absent).
• Be sure to submit a self-evaluation rubric with your project.

## Priority Standards Assessed:

• PS 7 – Solve problems using the derivative analytically, graphically, numerically, and verbally for a variety of problems (including optimization, related rates, and rectilinear motion).
• PS 9 – Solve problems including those that model area, volume and surface area.

You will be demonstrating your understanding of applying calculus to real world problems and showing your knowledge of implicit differentiation when solving related rates problems.

1. Choose two related rates problems to write a full report about. These should be from the provided examples and may not be the same problems as other students. You may choose your problem on a first come, first serve basis.
1. To earn full credit, your two problems must include two of the four features below:
1. Area of two-dimensional surface
2. Volume of a three-dimensional space
• Surface Area of a three-dimensional object
1. Angles requiring the use of trigonometric functions.
1. A written description of the problem you are trying to solve.
2. CLEAR question your problem is working to answer (i.e. What is the speed that the top of the ladder is falling when the ladder is 3 feet from the ground?).
3. Any formulas used to solve the problem (area, volume, surface area, Pythagorean Theorem, angles, etc.)
4. Clear description of all variables and derivatives and their units used to solve the problem and values you know as part of the problem (using the table may help).
5. A calculus appropriate picture of the problem you are trying to solve (including any measurements including units and variables you know or are working to solve).
7. A paragraph summary statement of the problem and answer in context written so a Geometry student could understand the setup and the meaning of the solution.
2. Grade your own project according to the Rubric based on what you think. You can go back and edit your project if you realized you missed something.

## Rubric

 Standard Description 1 Never Present 2 Sometimes Present 3 Regularly Present 4 Always present PS 7 – Solve problems using the derivative analytically, graphically, numerically, and verbally for a variety of problems (including optimization, related rates, and rectilinear motion).   Overall Score:   _____________ Student presents a well written question and interprets the problem for the reader. Student uses implicit differentiation to solve the problem. Picture provided aids any reader in better understanding the question being asked. Values and variables are labeled in the picture. Student interprets the answer for the reader and puts numbers into usable meanings. PS9 – Solve problems including those that model area, volume and surface area.     Overall Score:   _____________ Students have 2 of the 4 required types of related rates problems. Student demonstrates understanding of formulas needed to solve the problem. Student demonstrates understanding of variables used. Student correctly answers the question showing all work leading to the answer.
