How much snow is that?


Click image to see larger.

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?

The Forever Roll

Clicking on this image will show it larger in a new window.

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?
