Reflection: Staircase of Complexity Water Changes The Shape of The Land - Section 4: What Did We Notice?

 

This year students have been making predictions, testing out their hypothesis and then looking back at their predictions. Second graders often want the prediction to match the final outcome and when it doesn't, they quickly try to change the prediction.

This was the first lesson this year where students made a prediction, tested it and then wrote their results without trying to change the original prediction to match the results exactly. For the most part students predicted that the dirt would run down the hill, but the fact that the water formed into small streams and carried the dirt down the hill with it is not exactly what they expected. They were willing to leave their original prediction. 

This is a step towards internalizing the scientific process of conducting an experiment and I was excited by this unexpected outcome.
