Exit Ticket (Exit Slip) FREEBIE - Masses of Gases

This document contains 3 exit tickets on a page for quick formative assessments of understanding. There is also a technical writing component incorporated.

In this exit ticket, students are given a scenario about a gas being added to a balloon. The balloon begins to rise (float). Students are asked about how this effects the mass of the balloon. After choosing a statement that they agree with, the student must explain/describe their thinking on the back of the exit ticket. A teacher answer key/explanation is included.

The purpose of this Exit Ticket is to elicit students’ ideas about the masses of gases. It is designed to reveal whether or not students will recognize that an uninflated balloon will increase in mass when inflated with a gas, even though the balloon naturally seems lighter when it floats in the air.
