Putt Putt Boat Follow Up Report

The Putt-Putt Boat Follow Up Report is due Monday May 7th 2012

Below is the outline of the task:

Putt-Putt Boat Follow Up Report

Goal

To demonstrate your understanding of the Science behind the Putt-Putt Boat.

To begin, please read through the information provided in the following link:

http://www.sciencetoymaker.org/boat/howBoatWorksl.html

You may also want to review the second video in the Putt-Putt Boat Playlist. Watch the portion from 1:44 – 2:52. This information will help you understand the Science behind how the engine works.

Please answer the following questions in paragraph form.

1. Draw a “cross-section” diagram of your engine. A cross-section is a diagram that shows what something looks like on the inside; it looks like it has been cut in half. An example of a cross-section diagram can be seen on the link shared above.

Label the following on your cross-section diagram.

a)      All changes of state that may be occurring

b)      All energy transformations that may be occurring e.g., chemical to thermal

c)       What thermal energy transfers are taking place (conduction, convection, radiation)

2. Answer the following question in as much detail as possible.

In your own words, explain how the Putt-Putt Boat engine works.

Your answer should be no less than half of a page and no more than one full page typed. Remember to review the information on the link!

3. Personal Response

In this section, please provide a personal response about your experience building the Putt-Putt Boat.

Consider the following topics for discussion:

• Technical problems you encountered and how you solved them
• How well your group worked with each other
• What you learned when working on this project

Success Criteria

Diagram

All the information is accurately labelled with changes of state, heat transfer and energy transformations

Drawn neatly, used a ruler

Used a pencil, no colour

Scientific Explanation

Includes a lot of detail, clear

Scientific vocabulary is used

In your own words

Does the answer make sense? Correct information

Personal Response

Personal thoughts and feeling are clearly shared

Relates to personal experiences
