The tallest living dog stands 1.23 yds from foot to withers. When
standing on his hind legs, the dog, Zeus, is about 7.5 ft tall. Zeus weighs
11 stone. He eats about 12 cups of dog food a day.
Using dimensional analysis, convert all of the measurements in the
previous statement into either meters, kilograms or liters.
1 yard = 3 feet
1 foot = 0.3048 meters
1 stone = 14 pounds
1 pound = 453.6 grams
1 gram = 0.001 kg
1 cup = 8 ounces
1 liter = 33.814 ounces
Homework Discussion
Take 5 minutes with your table group to discuss
your Mump Population homework.
After 5 minutes, I will display the answers I got.
Dimensional Analysis Quiz on Friday
Open notebook.
All dimensional analysis work must be shown.
Create a quiz question
Your group will have 15 minutes to create a dimensional
analysis question that you think would be appropriate for
the quiz on Friday.
The question must require the use of at least 3 conversion
factors.
Show all work on whiteboard AND a lined piece of paper,
including how the problem will be solved.
At the end of the class period, I will collect the lined piece of
paper. It must include a heading with all group member
names.
