Reflection: Grade Book and Data Analysis Scientific Method - Section 5: Elaborate


I have found that the easiest way to grade labs is to use rubrics.  For most labs I use the 4 point rubric of 1- emerging to 4-mastery with statements of what I expect for each section at each level. 

For this specific lab rubric I had four sections including Problem/Hypothesis, Data, Analysis and Conclusion.  For each section I have a description of what it meant if students earned a 1, 2, 3, or 4. 

In the student lab example that I have attached the student earned 16/16 because she had mastery for each category.   The most common places where students made mistakes in this lab include:

1. Correct rounding, sig figs, and units in the Data section

2. Appropriate graph titles in the Analysis section

3. How a source of error would affect results and how to change the lab to prevent the error.

Scientific Method

Unit 1: Unit 1: Working as a chemist
Lesson 3 of 9

Objective: Students will be able to explain how to set up an experiment, including the use of variables, by taking notes, performing an experiment, and analyzing the experiment's results.

Big Idea: Scientific experimentation is complex and needs to be explored in multiple ways.
