Asking Questions and Defining Problems Using MND

Asking Questions and Defining Problems

An important scientific practice is the asking and refining of questions that lead to rich descriptions, explanations, and reasoning of how the natural and designed world works, as well as those investigations of variables that can be empirically tested.

Students at any grade level should be able to ask questions of each other about the texts they read, the features of the phenomena they observe and the conclusions they draw from their models or scientific investigations (NRC Framework, 2012, p 52)

Example Questions:


  1. Why are some areas of the world's oceans warmer than others? saltier than others?
  2. How might the sea surface temperature and salinity data look different in throughout the year?
  3. How does temperature affect salinity in the ocean? 
  4. How does temperature vary by latitude?  Why?
  5.  What processes change the salinity of the seawater?
