Dry Ice Lab
- Dry Ice Experiment (45 min): In this experiment, students will be utilizing the scientific method to ultimately calculate the volume of dry ice that is equal to the quantity of CO2 that is generated each year by a typical American family. Key curricular concepts that will be covered include the phases of matter, density, and a concrete understanding of the measure of one ton of CO2. ( Resources used: BOCES Density Kits)
Density of dry ice is > H2O or > 1 g/cc.
Density of CO2
1.562 g/mL (solid at 1 atm and -78.5 °C)
1.977 g/L (gas at 1 atm and 0 °C)
1090F below zero.
1 ton of CO2 gas is equal to 459,281 L
A 14m x 14m x 3m classroom is 588,000L
1 ton = 2,000 lbs x 454 g / 1 lbs x 1 L CO2 / 1.977 g = 459,281 L
1 Classroom = 14m x 14m x 3m x 1,000,000 cc / m3 x 1 L / 1,000 cc = 588,000 L
Fun stuff with CO2
All students get a surgical glove plastic cup spoon full of Dry Ice in there cup.
They put the glove over the top of there cup without spilling dry ice. They will see the gloves fill up with ?????
Then the students are given a small cup of H2O. They remove the surgical glove and add H2O over the top of their dry ice.

Objective: Calculate the volume of dry ice that is equal to the quantity of CO2 that is generated each year by a typical American family.
The density of CO2 gas at 00 C and 1 atm of Pressure = 1.977 g/L
The Density of Air at 00 C and 1 atm of Pressure = 1.2754 g/L
1 ton (US) of CO2 gas is equal to 459,281 L
A 14m x 12m x 3m classroom is 504,000 L
A typical American Family is a 5 person Household generating 130 Tons of CO2 eq/year.
How many classroom equivalents are there in Cuba Elementary School?
Set up and observe the sublimation of Dry Ice in a cup with a surgical glove over it.
Set up and observe the sublimation of Dry Ice in a cup submersed in water.
