DO NOW 1.DO NOT get your supplies 2.Take out your “Rube” ric 3.Homework: Edit/Revise Calorimeter Paragraph

Rube Schedule 16 th and 17 th - Discuss diagram and work on your machine 18 th and 21 st – Work on your machine and meet with me about the diagram 22 nd and 23 rd – Rube must work; Record with I Pads 1/4 & 1/7 – Create an I Movie 1/8 & 1/9 – Final diagram due

A step is when energy is transferred from one object to another. There may be multiple transformations at one time. Some objects will have more than one arrow “How to….” No potential or kinetic, the forms must be intentional (no heat from friction or clicking of dominoes )

Why is it inefficient? Discuss sound and friction! Cannot change! I need to see quality work! Use a large blank sheet of paper. Make sure your drawing fills the paper. Color it!

When the ball hits the books, mechanical energy from the ball is transferred to the books. 2. Mechanical energy from the books is transferred to the lamp when the books press the button on the lamp. 3. Mechanical energy changes to electrical energy when the button is pressed. 4. Electrical energy changes to electromagnetic when the light turns on. How to Turn on a Lamp This should be a short paragraph that explains all of wasted/inefficient energy. You do not need to explain each step individually, instead give a general explanation. What is the source of the wasted energy? Why is there wasted energy? Why is this energy not useful in your machine? Make sure to discuss friction! Efficient Transformations Wasted Energy Key M = Mechanical E=Electrical Etc…

How to… Chemical energy from the battery changes to electric energy when the boy uses the remote. 2. The electric energy changes to electromagnetic energy as it sends a signal to the car 3. The electromagnetic energy releases the chemical energy in the battery of the car Wasted Energy paragraph goes here. Key M = Mechanical E=Electrical Etc…

1.Draw your machine 2.Create a key 3.Draw in numbered arrows and letters to represent energy 4.Write a sentence for each arrow, explaining the transformation. Rough Draft

Some Important Info A step is when energy is transferred from one object to another. There may be multiple transformations at one time. Some objects will have more than one arrow You cannot count potential or kinetic energy. The forms of energy in your machine must be intentional. (No heat from friction or clicking of dominoes ) You must discuss friction in your wasted energy paragraph. I need to see quality work! Use a large blank sheet of paper. Make sure your drawing fills the paper. Color it!
