This experiment helped answer the question "does cryogenics freezing really work on worms?". This question was asked because scientists still do not have the technology or procedure to revive one that has been frozen. If organisms are cooled longer than others, they would move slower once they have warmed up to room temperature. Instead of using large organisms, red wigglers (not harmful worms) were used. In this project there were two trials. In the first trial the times tested were five minutes, fifteen minutes, twenty-five minutes, thirty-five minutes, and one hour. On the second trial, the same times were tested, but fifty-five minutes were added. All variables were controlled except the time the worms were in the freezer. The procedure starts off with labelling six disposable metal containers and six disposable plastic containers with the times listed above. All of the plastic containers were filled with soil and lettuce. There was an extra disposable plastic container(also filled with soil and lettuce), the worms were picked from the compost box and placed in the extra container. Then for each worm, they were given an ice bath to lower their temperatures for two minutes, then each worm was placed in the freezer for a specific amount of time. In conclusion, all the worms lived except the fifty-five minute worm and the one hour worms; also, the worms did move slower so my hypothesis was accepted.
