## Reflection: Connection to Prior Knowledge Gravity Powered Marble Mover (Day 1) - Section 2: Warm Up

Why Use a KWL Chart with this Lesson

I chose to use a KWL chart to begin this unit because knowledge about gravity is something that almost all students entering 5th grade have.   What they know about gravity varies, but most know it holds us on Earth and makes things fall down towards Earth.  By doing the KWL chart, I am able to see what they know, what they want to know, and then later, what the have learned.  Some students may have some misconceptions about what gravity is or does and this will allow me to identify those as well.  I can address misconceptions during lessons throughout the unit as well.

The L (learned) section will be completed at the end of the 2 day lesson.  I will go over all of the sticky notes from the W (want to know) section and have students answer those questions.  As they give me the answers I will record the information under the L section as things they learned throughout the lesson.  I will then have students write down one additional thing they learned about gravity on another sticky and have them add it to this section.  Throughout the two day lesson I hope to answer every question they had, teach them everything they wanted to learn, and hopefully give them a little more information they find interesting.
