Students in Ms. Sema Krishna’s art class during Summer Bridge Academy learned about density and molecules through a painting session with paper-mache balloons Tuesday morning at Cordova Middle School.
Roger Greer and Braye Chavis paint their balloons white, using a few spare copies of the Daily Journal to cover the balloons. Over 100 students participated in the Summer Bridge Academy this summer.

The video explained how air is made of matter, which is made of molecules, which can heat up causing a difference in density between the air in and outside of the balloon.
Bella Sweatt and Kierra Williams paint their balloons. Once they finish drying, they will hang in and decorate the classroom until they are ready to go home.
Students learned the technique of gesso, pronounced jesso, a process used to prime a surface so oil paint will adhere to it. “If a mistake happens, just like anything else, you learn from it,” said Ms. Krishna.
