Start out this activity with: *What do you notice?* *What do you wonder?*

How many inches of snow produced that pile? How much snow in volume is on top of the car? How much could that snow weigh?

Students try to approximate the weight of the snow by using our snow water equivalent percents (SWE) and their own thoughts about how dense this snow might be. When they've calculated a weight or range of weights, we try to decide whether the car should have been flattened by all of that snow. Wicked fun! Is this even possible or was this picture photoshopped?

That's a big roll of toilet paper! Why would anyone need such a big roll of toilet paper? How does it compare to Charmin's other toilet paper products? If this roll lasts for one month, how big a roll would I need to be able to last for one year? Why did Charmin make this product? Will it sell?

Should I oven bake it, deep fry it or barbecue and smoke it? When do I have to wake up to begin preparations? How long will the cooking take? How much will it cost? How many can I feed? Will there be enough mashed potatoes? I feel panic coming on!
