## Reflection: Developing a Conceptual Understanding Gravity (Part 1) - Section 5: Explore Part 3

We see the reoccurrence in this lesson of two Crosscutting Concepts, Patterns and Cause and Effect. Your students may struggle with how best to represent the falling and tossing motions using velocity over time graphs.

I make sure to take the time to go back to what we know about graphing glossy overtime graphs when the motion is forwards and backwards or left to right and the types of lines we used to create those graphs. I've been bridge that knowledge with what they don't yet know in that is how to create a very similar looking graph when the motion is up and down.

Students will catch on fairly quickly but it's a good idea to guide them through the construction of these graphs first before letting them make several mistakes and then have to go back and correct them.
