Dry Ice Investigations

Questions We Have About Dry Ice

Student Questions After “Exploring Dry Ice” If you put water in with dry ice, will it freeze? Would a normal thermometer break if you put it against dry ice? If dry ice were to melt, would it be edible? What would happen if you put dry ice in a hot oven? What would happen if you covered dry ice with sugar?

Systematic Observations Marge’s Systematic Observation – What happens when you put dry ice in soap solution? The Mystery of the Floating Bubbles

Activity 3: Experimenting Marge’s Experiments – Does temperature affect how fast dry ice turns to a gas?

Student Questions After “Marge’s Experiment” What would happen if you placed dry ice on a marshmallow? … on a bunsen burner? … in Pepsi?… in Jello? … in hydrogen peroxide? … on a plant leaf? … in salt water? What would happen if you put acid on dry ice? What would happen if you mixed dry ice with gasoline? What would happen if you wrap it in foil and put it in hot water? What would happen to a fish in water if you added dry ice?

Activity 4: Conducting Dry Ice Investigations Choosing Investigable Question Making an Investigation Plan Conducting Investigations Sharing Results of Investigations

Assessment Scientific Journal – observe, compare, describe Energy and Matter questionnaire Open-ended Investigations – Investigation Rubric Other Suggestions: Investigate another topic, design a comic strip, “The Royal Society Meets”, Inventive Applications
