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.

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.

Homework• Use the Mump Island conversion factors from

page 18 to solve the dimensional analysis problems on pages 20 and 21.
