Letter to School Board Class Brainstorm

Letter to Board of Education Class Brainstorm:

·         make the windows open more- passive design- wouldn't need to buy AC
·         new light bulbs- we recommend fluorescent bulbs
·         solar panels
·         No portables- insulation! they have cardboard walls
·         energy efficient appliances* in the school cafeteria
·         try to make the school energy efficient
·         replace light bulbs to be fluorescent- last a long time, may cost more up front, but save money over time, don't give off as much TE, saves energy
·         solar panels- schools remain open for a very long time, solar panels will create low energy bills and run, most of the appliances in the school on sunlight, which is a renewable resource
·         buy new energy efficient appliances in the school kitchen, prevent TE loss
·         buy frames for windows that are fiberglass or wood, double pane, and open more to get a breeze
·         Duct system for heating/cooling- thermostat!


Letters due tomorrow! 

Letter to the School Board

 
Homework due - you will write a letter to a school board using the scenario below. 

"Your community is building a new school on a tight budget. The town planners do NOT want to buy energy-efficient equipment for the school because it will cost more. Do you think the town should or should not buy energy-efficient equipment? Why or why not?"

Make sure you:

·          Constants: things you keep the same in an experiment
·         Control: no independent variable; used to compare with data to see if variable affects results
·         Observation: describing something using your 5 senses
·          Qualitative: qualities of an object ex: round, blue
·          Quantitative: describing an object using number ex: 5 cm wide
·         Materials: the stuff you use in your experiment
·         Procedure: the steps you follow to test the hypothesis
·         Data: the results collected
·         Errors: mistakes made during the lab that may affect results
·         Conclusion: answer your problem question, back up your analysis with data
·         Energy: causes objects to move, change, or do work
·         trade-off: give up something to get something
·         consumption: to use up
·          potential energy: stored energy that has not yet been used
·          GPE: energy based on gravity and position above the ground
·          kinetic energy: energy of motion
·          Transfer: to move from object to object
·          Transform: to change from one form into another GPE à KE

Drive a Nail Lab Report due FRIDAY Sept 13

Make sure pages 1 and 2 are completed in your lab packet by class tomorrow. Tomorrow in class you will be following your procedure and gathering data.

Sample Procedure that group 003 made up:
1. gather materials
2. grab foam block and put nail in a fresh spot 0.5 cm down
3.grab the small plastic tube and put vertically over the nail
4.hold the plastic tube- grab the small steel rod
let it drop count how many times you drop it lift up the plastic tube and continue counting
5. record results in data table

6. repeat steps 1-5 with large plastic tube and other rods.
