UNIT 4 Heat and Thermodynamics

Assignment One

Answer the following three questions in your own words and post your answers to the discussion page.

What is energy????

How is energy transferred in our Environment? What is work? [|Work Equations and Formulas Calculator]

Assignment 2 In your own words give the definition for the following vocabulary words for this section. Post you thoughts to the discussion board for this page. Please remember I want to know what you think these words mean.

Work Heat Thermodynamics Energy Engine Heat engine Internal energy Energy of motion

Assignment three to be presented in class Presentations: Give a 2-3 minute presentations on your assigned topic. You may use power-point visual aids and outside sources in-order to insure the classes understanding of the topic.

**Identify** the cycle of a heat engine. **Identify** energy and how it is transferred ||
 * This is what you should be able to do after this unit: ||  ||
 * **Demonstrate** an understanding that heat flow and work are two forms of energy transfer


 * __Here is how we will get there:__ ||
 * **Create** a project showing the work done by a heat engine.

**Identify** that most processes tend to decrease the order of a system over time, so that energy levels eventually are distributed more uniformly. || **Identify** variables effecting experiments
 * **Display** measurements and data graphically

**Show understanding** that internal energy of an object includes the energy of random motion of the object's atoms and molecules//.// || __Making Connections__ || = = =__**Project Description:**__=
 * **Determine** that **t**he greater the temperature of the object, the greater the energy of motion of the atoms and molecules that make up the object. ||
 * **Apply** the process of analysis comparing results to others completing the same experiments. ||
 * __Taking a Critical Stance__ ||
 * **Display and Analyze** measurements and data graphically through graphs and equations. ||  ||
 * **Display and Analyze** measurements and data graphically through graphs and equations. ||  ||
 * **Display and Analyze** measurements and data graphically through graphs and equations. ||  ||
 * Boat Construction:** You must create a boat out of different materials that will travel the length of the metal tub without touching the sides. This will be a timed event. If your boat touches the sides you will lose points. 2 points each time it hits the sides and 1 point for every second it runs along the side. The boats may not exceed 12” in length.

[|**http://www.sciencetoymaker.org/boat/makeBoat4_07.htm**] Grading: A- Move the boat and weight successfully to the end without touching the sides in less than 45 seconds. B- Move the boat and weight to the end of the tank without touching the sides. C- Make the boat and the weight move ½ way down the track without touching the side D- Make the boat move halfway down the tank. The
 * Engine Construction:** Using the following website as your instruction students most create an engine for your boat. You will be required to have the engine power your boat across the tub.
 * Materials**: You will be required to collect the materials for this project. The candles for the engines will be provided.

The The Write up:

Complete a one page technical write-up that includes the usage of the following words. The words should be bold in your write-up and used in a way the demonstrates your understanding of the words meaning.

Work Heat Thermodynamics Energy Engine Heat engine Internal energy Energy of motion

Your Please cover the following topics in your write-up:

How successful was your project? Briefly explain your design. How did you approach the problem? What problems did you run into? How did you resolve them? Given the opportunity what would you do differently if assigned this project again? Please describe your contributions to the group effort.
