For the table, we'll refer to the columns as (A) through (D).
When filling out the columns, the information for (A) and (B) is in the lab already. For column (C) do your best to estimate. The calculation for column (D) is as follows:
(B) / 1000 X (C) = (D)
*for the hours used per day column you can use decimals too: 1minute = 0.017 hours. Like my coffee maker brews for 12 minutes, so 12 X 0.017 = 0.2 hours.
** for things like chargers and gaming systems, if they're plugged in they're drawng power (even if your not charging anything)
*** a fridge and hot water heater each run for 4-5 hours per day (more for the hot water heater if you use a lot of hot water in your home)
****for the light bulbs - count ALL bulbs in your home and guesstimate how long they're on for in each room.
When answering the analysis and conclusion questions use the following hints:
For question 1: Use the information from your table
For question 2: If in class - use the sample electric bill. Look for the letter "J." Then do "J" pres - "J" prev.
If at home - ask your grown-ups for your bill and some help.
For question 3: Take the answer from #2 and divide by the number of days in the month, which can be found using letter "O" on the electric bill.
For question 4: Compare yours (#1) to the sample/actual (#3). Is yours higher or lower? What could explain yours being different? For example, are a lot of lights left on in your home, do you do 4 loads of laundry per day, do you watch hours and hours of television, etc?
For question 5: use a cost of $0.06 per kwh to determine how much it costs to wash and dry your clothes.
For question 6: Is it high or low and WHY?
For question 7: Meter readers look at the first and last day and then estimate.
