## Reflection: Rigor Exploring Acceleration (Part 1) - Section 3: Explore Part 1

This lesson introduces a simple tool, the accelerometer. Many of your students are going to be surprised that the behavior of the accelerometer which will most likely be in contrast to their initial predictions.

This pushes their thinking to come up with an explanation of the behavior of the accelerometer and relate that back to the physical model of the cart that they have been exploring in previous lessons. This highlights the crosscutting concept of cause and effect.

The goal here being to develop an explanation for how this model works to be able to use that explanation to explain how phenomena outside the classroom work. The accelerometer model and tool will be revisited throughout the remainder of this unit so make sure to take time to get students understanding exactly what's going on, how the accelerometer works, and how it's a useful tool for understanding the cause and effect of acceleration.
