Reflection: Developing a Conceptual Understanding Pumpkins!! The Forgotten Fruit - Section 4: Estimating Seeds (Day Two)


When a scientist cannot use exact numbers or measurements in their work, they must rely on estimates to help them in their work.  Also, with estimating, scientists use what they know to help them make their estimates.  These can be closely related to inferences; the ability to take what you already know, combine it with what you are learning and formulate a new idea. 

A prediction is tied to an hypothesis.  The prediction is how a scientist will specifically test out the hypothesis.  

Be sure to clarify with students that estimates and predictions should not be changed after they have been made.  They are not considered wrong or failures.  They are simply new information that may not have been considered before the prediction or estimate was made.
