Reflection: Student Ownership Gravity Powered Marble Mover (Day 2) - Section 2: Explore


Reflecting on Changes Made 

Students were building, testing, adjusting, retesting, and so on throughout this unit.  As I circulated I was questioning the changes that were being made.  Students were telling me that the marble was getting stuck so they had to widen the ramp, or the marble wasn't hitting the ramp so it was falling out, etc.  They were noticing the errors and adjusting accordingly but they did not have anywhere to note this.  I quickly noticed that having them make changes on their sheets would not work when they were making so many changes.  I knew some type of reflection sheet needed to be used.  I created the Engineering Design Working Plan that I will use in the future.  Each time the students notice a failure point they will stop, reflect on what is causing the failure and then plan how to adjust their model.  I think stopping and thinking through the change will help them better understand the importance of the reflections and making good adjustments.

Gravity Powered Marble Mover (Day 2)

Unit 4: Motion, Forces and Interactions
Lesson 4 of 11

Objective: SWBAT use the engineering design process to create a structure that uses the force of gravity to get a marble from the top, to a cup located at the bottom.

Big Idea: Students earn points for adding in a variety of ramps, loops, and jumps into the structure they build to move their marble to a cup.
