If you find yourself with some extra dry ice, or you are just looking for something really fun to do with toddler thru upper elementary school students, then you will want to try this activity. It\u2019s sure to appeal to the aspiring chemist in your child! (I had dry ice because my awesome friends sent food to help me cope with the anguish of colic<\/a>. The food arrived in Styrofoam coolers, and I was delighted to find dry ice inside. I made sure it didn\u2019t go to waste!) If you don\u2019t have dry ice on-hand, you can purchase a block of dry ice at your grocery store. The cooler is usually in the front of the store by the regular ice. It usually costs anywhere from $5.00-$8.00 per pound.<\/p>\n REQUISITE WARNINGS AND CAUTIONS: If you aren\u2019t comfortable handling dry ice with tongs, you will want to wear rubber gloves or an oven mitt. Dry ice can burn your skin through prolonged exposure (think: frostbite), so be sure to CONSCIOUSLY SUPERVISE YOUNG CHILDREN around dry ice and provide plenty of warnings about the dangers of dry ice and bare skin. Also, be sure to perform this activity in a well-ventilated area. (It\u2019s highly unlikely with the quantity you would be using, but too much carbon dioxide gas can be problematic to your health. But, I have to put the warning out there.) It\u2019s always a good idea to wear eye protection as well. Dry ice produces the best results when mixed with warm or hot water, so be sure to supervise those efforts very carefully as well. Boiling water is not necessary. I used hot-out-of-the-tap water (which you will need to replenish as the dry ice absorbs the heat energy of the water).<\/p>\n Add food coloring to warm water. Have your child place their hands on the outside of the container (if it isn\u2019t too hot) and state an observation. \u201cWhat does it feel like?\u201d \u201cIs it warm or cold?\u201d<\/p>\n Add soap to your ONE container of warm, food-colored water.<\/p>\n You can blow on the dry ice and your warm breath will speed up the process of going from a solid to a gas (creating \u201csmoke\u201d). Ask your child to place their hand near the smoke as you blow or hover their hand just over the ice. Ask, \u201cWhat do you observe? Is the ice hot or cold?\u201d<\/p>\n Using tongs or gloved hands, carefully drop a few chunks of dry ice into your containers of warm water. Before you release the dry ice, ask your child \u201cWhat do you think will happen when I put this cold chunk of dry ice into the warm water?\u201d These sorts of inquiry-based observations have scientific method written all over them, and I just can\u2019t get enough of that in my or my toddler\u2019s life!<\/p>\n This guy loved seeing the \u201csmoke,\u201d as he called it. \u201cIt\u2019s magic,\u201d he proclaimed. The chunks of dry ice appear to boil in the warm water, and fog is released as the dry ice absorbs the heat energy from the water and sublimates from a solid into a gas. My toddler thought this was awesome, and I made sure to ask \u201cWhat do you observe?\u201d \u201cWhat do you think is happening to the dry ice?\u201d<\/p>\n Now it\u2019s time to play and discover and learn!<\/p>\n Beaker with no soap. \u201cFog\u201d only.<\/p>\n Flask with soap added. \u201cFog\u201d bubbles when popped!<\/p>\n My toddler loved popping the soap bubbles and helping the gas escape!<\/p>\n Time for a closer look! Get me my hand lens!<\/p>\n Holding bubbles and clapping hands made for a cool effect.<\/p>\n Science is fun, and it\u2019s never too early for inquiry-based learning!<\/p>\n Before you finish your activity, be sure to observe what happens when you add hot water directly to the temperature-safe container of dry ice!<\/p>\n Why do I love dry ice? Dry ice is a very cool (no pun intended) substance that is technically simultaneously a solid liquid gas. Plus, I love that you can get your hands on it quite readily (as opposed to liquid nitrogen or liquid helium). To somewhat oversimplify the science: if you think of water \u2013 solid water is ice, it melts into liquid water, and then it can change into a gas form of steam when heat energy is applied? Water evaporates. Dry ice doesn\u2019t evaporate. Rather, dry ice is a rare piece of MATTER and it sublimates \u2013 it goes from a solid into a gas. Essentially, the air is boiling the dry ice. How cool is that?<\/p>\n Carbon dioxide as a gas is heavier than the air we breathe, so when warm water is added, it speeds up the sublimation process (heat energy is awesome!!). What you observe is a fog or smoke effect that is highly sought to enhance Halloween parties and music videos alike. You can see in the photo below that the fog is rising above the lip of the bowl and then falling rather than floating into the air. You can observe coolness in temperature if you place your hand over or (carefully) inside the \u201cfog.\u201d (Think: heat rises, cool \u201cair\u201d sinks).<\/p>\n If you are interested in extending this to older children (or even want to go next-level with your toddler), you can compare and contrast what happens with water ice when added to warm containers of soapy water. Prompt your child to compare the reactions of what happens when dry ice is added to warm water without soap and water ice is added to warm water without soap. Do the same for warm water with soap added.<\/p>\n You can also have your child discuss what happens to the speed at which dry ice sublimates at room temperature (sitting in a bowl or Pyrex) and what happens to sublimation speed when dry ice is placed in warm water.<\/p>\n I think the key here with any aspect of this activity is having your child make PREDICTIONS, ask QUESTIONS, and make OBSERVATIONS to formulate CONCLUSIONS based on the aforementioned parts of the scientific method. Even the tiniest scientist is capable to making brilliant assessments of inquiry!<\/p>\n This was originally posted by Sarah Caughton on her blog, <\/em>The Sisterhood of the Training Pants<\/a>.
