Reflection: Student Ownership Sink or Float - An Introduction to Buoyancy and Density - Section 4: Independent Practice and Informal Assessment


I like to wrap up my lessons with independent practice whenever possible.  For this lesson, the students created a simple diagram that summarized information from the investigation we completed.  Some might say that this is busy work, but I believe differently.

The entire time I was presenting this activity to the students, I was positioning the activity as something important that scientists do.  You will hear me say thing like , "Scientists might summarize information they have gathered from an experiment by creating a diagram.  This diagram allows them share results with people who were not able to be present during the experiment.  This activity serves many purposes.  The students learn the importance of summarizing information from a scientific investigation.  They get practice creating a diagram, but most importantly, they have a piece of paper that they can take home to their families to explain what happened during their experiment.  They can show their family exactly what happened and use this as a springboard for conversation about the activity.  They are given the opportunity to practice using their scientific language and explain concepts to an audience who was not able to experience the investigation first hand.  This is great practice for my students!

I heard from several parents about the great conversations that they are having at home about our science activities.  The parents are amazed with the vocabulary and thrilled with the enthusiasm the students show.  I will continue to make this home to school bridge more prominent in my lessons and motivate my students in different ways to share their learning with their families.
