Reflection: Real World Applications Crashing Cars - Section 4: Evaluate


This lesson was fun. It was busy. It was hands on. It was difficult for my students to make observations in their notebooks.  They were SO excited to be playing with cars, they forgot about their "science" roles. They also loved the Mythbusters video clip. In the future, I will have a mandatory stop time for all students to stop and record observations at various points in the exploration.  Many students were able to identify that one of their cars was heavier than the other car thus altering the experiment. Students were able to identify that the heavier car seemed to go slower on the ramp and therefore didn't pick up the same amount of speed. I was happy that students were making these observations.  

This lesson directly relates to increasing or improving the frequency that my students use appropriate and precise science vocabulary?  While the science notebooks do not reflect the language my students were using, they did do an excellent job at using some of the important vocabulary terms when conducting the explorations and talking with peers. My students were using the words potential energy, gravitational energy, collisions, energy , speed and mass.  I know I have work ahead of me to get these words to also be replicated in their notebooks as well. One reason I believe students were careful to use this precise language during the exploration is because they were replicating what I have modeled. I realized during this lesson that I model lots of verbal language, but need to also model written language while using precise language. This was a huge "ah-ha" moment for me.

Crashing Cars

Unit 1: Speed and Energy
Lesson 4 of 5

Objective: SWBAT predict outcomes about the changes in energy that occur when objects collide.

Big Idea: In this lesson, students use toy cars and observe what happens when the cars collide.
