unknownnnnn asked:


i wrote my research paper on cryogenics, and did a experiment but it didn’t work out. my only option is to do a new experiment. I have 7 days, and it has to have something to do w/ cryogenics. (Cryogenics is freezing stuff basically) If ANYONE has any ideas i’d reallllly appreciate them because i’m at a total loss.

   I think you’ve touched on the main problem with cryogenics here - it’s not just your experiment that didn’t work out, but everyone else’s as well. They have not yet successfully frozen someone and then revived them.

   Here’s part of the problem. We have a lot of water in our bodies, and when water freezes, it expands (that’s why ice cubes are bigger in volume than the water you started with). When you freeze a person, the water in the cells expands and breaks through the cell walls. This also happens when you freeze a strawberry - the cells are ruptured by the expanding, freezing water. When you thaw it out, it’s all mushy. And a human is the same way.

   Try freezing some strawberries and documenting the defrosting to show how cryogenics doesn’t work yet. Try using some other ways to freeze it as well as the fridge - like liquid nitrogen (if you can get ahold of it).

   First of all, your terminology should be a bit clearer. “Cryogenics” refers to low temperature physics, below minus 100 degrees Celcius, like the temperatures of liquid nitrogen and oxygen in the space shuttle. “Cryonics” is the cryopreservation of humans and pets in anticipation of future reanimation (with technology that won’t be available for decades). If you are doing a simple freezing experiment with an organism, that would be “Cryobiology”. (Cryonics does NOT involve freezing, cryonics companies use anti-freeze compounds to prevent ice formation.)

   If you are looking for a science fair project involving cryobiology, then go to the International Cryobiology Young Researcher’s Group website at the 3rd link I have given below.

   You can’t expect all science fair projects to result in a success. As a matter of fact, it’s only the simpliest experiments that will result in a success, that’s why people do them. Your research paper can talk about how your experiement failed, and the possible reasons it did.

   Science is made up of far more failures, than successes. It is the failures that are the building blocks of success, so rather than thinking of your experiment as a failure, consider it a building block, that is absolutely valuable to future success.
