Reflection: Performance Tasks Is This Food Healthy? - Section 3: Closing

 

I use this lab as a performance assessment of my students' mastery of the science practice standards. I am specifically looking to see if my students can draft a hypothesis, record observations, use data in a conclusion, and share information with their group members. 

This year I conducted this lab towards the end of the school year. I was pleased to see that most students cited data in their conclusion. I was also pleased at the level of discourse between students. In each student group there was a debate about the healthiness of the food. During this debate, students were citing data and trying to convince others that their position was correct.
