4th graders at Frances K. Sweet learn how to make observations and create scientific questions during an ice balloon investigation. The investigation involves a frozen, water filled balloon and the students remove the latex and examine the ice using magnifying glasses, flashlights, toothpicks, popsicle sticks, and paper clips.  They then observe what happens when salt and food coloring are added.  Throughout the lesson, students document their observations and raise questions about what they see. Pictured here are 4th graders Ansel Espinal and Dona Lima from Mrs. Elish Mancuso’s class.
