Scientific Method

Patience: I am amazed at the level of patience my students have. We have been practicing the scientific method in preparation for the science fair. I did a simple experiment asking "How fast does snow melt?" 
We each got a little cup of snow and we set them out on the table. My initial plan was to move on with a math lesson while they melted in the background, but my students wanted to watch the cups melt. 

Some turned clear as they melted. Some had lots of water while they melted. Some just shrank. They were excited by every little change. 

We talked about how it was important that we didn't hold the cups because it would be "cheating" as the heat from our hands would melt it faster. We wondered why they were melting differently: some snow had come from the top layers and other from the bottom layers. 

Yup. 26 minutes we sat and watched snow melt. These kids are seriously extraordinary!

So... It should not come to my surprise that for the science fair, one group decided they wanted to see if glue dried faster on paper or on a pencil.... 

They hypothesized it would be faster on the pencil because since they hold the pencil, it would be warmer and the glue would dry faster. Sound logic to me!
