Snow Problem

Snow Problem

While we were shoveling, Himself wondered how much snow he had shoveled. Those are the kinds of things a mathlete thinks about. He decided to give his students an extra credit problem based on the following data. Can you solve the problems? Don't forget to show your work.

Data:

Driveway                                               rectangle 95 ft x 17 ft
Avg snow depth - Storm 1/27/2015     24 in.
Avg snow depth - Storm 2/2/2015       15 in
1 shovel of snow                                   1 bucket
bucket                                                   cylinder: 35 cm in length and 30 cm in diameter
mass of bucket                                      1.9 lbs
mass of bucket + snow                         10.1 lbs
time shoveling snow - Storm 1             4.5 hrs
time shoveling snow - Storm 2             4.0 hrs
Calories burned shoveling by

hand                                                      549 Cal/hr


What is the total volume of snow on the driveway for the two storms, (in cm³)?

     

What is the volume of 1 bucket of snow, (in cm³)?

What is the total number of shovels of snow for the two storms?

What is the mass, in grams, of snow in 1 bucket?

What is the average density of the snow, (in g/cm³)?

What is the total mass of snow shoveled in the two storms, (in metric tonnes)?

How many Calories did I burn while shoveling for the two storms?

The Friday Five Good Things

Five good things that happened this week

1. Art supplies arrived before the big storm

2. Played with the Gelli plate and made some monoprints

3. Made Inchies and Twinchies

4. Though I don't consider shoveling to be something to look forward to or get excited about, I did enjoy helping Himself shovel. Misery loves company.

5. Got part of my Spring teaching schedule.

How was your week?

Throwback Thursday

It's snowing again. I'm sick of looking at the stuff and sick of the talk of it. So I spent the morning lost in photographs trying to find a picture that didn't have snow in it.

This is from August 1996. Look how green everything is. It's a warm day.  The Eldest, 10, is barefoot. The Young One is 4. The Eldest had a  butterfly farm and the girlies are setting the butterflies free.

Is it August, yet?

Wordless Wednesday

Gelli Plate

In the supplies I ordered, I splurged and got a Gelli plate. It's a way of monoprinting without a press. Since it was snowing (again) on Monday, I decided it would be a good time to play.

The 8" x 10" plate seemed a little daunting, and I didn't care for the first attempt. So I cut a sheet of mixed media paper into 3" strips.

Smear some acrylic paint. Roll it out with a brayer. Make some marks with stamps, found objects. Lay down the paper, smooth with hand, and lift up. The first strip on the left was meh. I liked the second pull with middle strip much better. I rolled a ball of yarn around the third strip. I liked that effect, too.

Have you used a Gelli plate?
