Implementing Educational Program
Big Dry Ice Bubble
In our Therapeutic Recreation Department, we offer science experiment programs twice a month. I as the Director, search the internet for science experiments that my male residents suggest. These science experiments assist my male residents in stimulating their brain and they contribute to their quality of life. These programs range from 30 minutes to an hour in time length and our male residents enjoy partaking in this male group activity. This particular program is person-centered and it encourages participation, discussion, stimulates the brain, and is meaningful as well as enjoyable to our male residents. Because the brain has the ability to change throughout an individual’s life, learning new concepts and sharpening their minds continue to occur late in life in adults.
These experiments meets the intellectual needs and interests of our male residents.
Water, Safety Gear(Gloves, Masks)
A large bowl with a lip around the top (a smaller bowl or cup will work too)
A strip of material or cloth
Soapy mixture for making bubbles (water and some dishwashing liquid should do the trick)
Dry ice - one piece for a cup, more for a bowl. Places where adults can buy dry ice include large grocery stores and Walmart. Butchers and ice cream stores might have some too.
Safety first! Be careful with dry ice as it can cause skin damage if not used safely. Adults should handle dry ice with gloves and avoid directly breathing in the vapor
Place your dry ice in the bowl and add some water (it should start looking like a spooky cauldron).
Soak the material in your soapy mixture and run it around the lip of the bowl before dragging it across the top of the bowl to form a bubble layer over the dry ice. Stand back and watch your bubble grow
Task 1: Set up long table with plastic table cloth. Place bowl with lip around the top on table along with goves, mask, strip of material or cloth, dishwashing liquid, another bowl with water.
Task 2: Assist and/ or direct male residents to Activity Room if needed. Have them seated around the table.
Task 3: Ask for volunteer of a male resident to mix up soapy mixture of dishwashing liquid and water and then place cloth in solution.
Task 4: Get dry ice as residents socialize.
Task 5: Allow each resident to put mask on to avoid breathing in vapor directly.
Task 6: Inform residents to move away from table. I will place the dry ice in the bowl and add some water.
Task 7: I will then take the soapy cloth out of mixture and run it across the lip of the bowl then drag the cloth across top of bowl to form a bubble layer over the dry ice.
Task 8: I then stand back along with residents to watch the bubble grow, then bubble explodes of fog over edge of bowl.
My residents and myself were intrigued on how the bubble formed then exploded into fog. More experiments to come says my male residents…Smile.
Dry ice is carbon dioxide (CO2) in its solid form. At temperatures above -56.4 °C (-69.5 °F), dry ice changes directly from a solid to a gas, without ever being a liquid. This process is called sublimation. When dry ice is put in water it accelerates the sublimation process, creating clouds of fog that fill up your dry ice bubble until the pressure becomes too much and the bubble explodes, spilling fog over the edge of the bowl. Dry ice is sometimes used as part of theater productions and performances to create a dense foggy effect. It is also used to preserve food, freeze lab samples and even to make ice cream!
