Introduction

Earthworms live in soil and get nutrients from eating the dirt and can eat ⅓ of its body weight, if they get too cold they will freeze and die.(Mrs. Harrison, 2017) When they are in the ground they go as far as 2 meters under and when they are getting cold they can go down further. (Journey North, Uknown time) This lab is important because it will help us understand how worms react to different temperatures of water. All earthworms live in the 2 to 3 inches of soil directly beneath the surface.(Unknown Author, Unknown time from http://animals.mom.me/effect-temperature-earthworm-population-6147.html) When temperature drops below 40 degrees, the worms will start to die off.

The cold water made the worm slow down while the warm water made it go faster. The cold water made worm 2 shrivel while the hot water made it elongate and made it jump away. The worms avoided the cold and warm puddles and not the room temperature puddle.

Conclusion

The data means that worms respond differently to the warm and cold water because the room temperature is what rain would feel like. My hypothesis was slightly correct/ supported because the worms freaked out from the warm and cold water but, the worm did not die from the cold water. Next time we could add ice water and scorch. In the end we figured out that worms hate all temperatures and are very sensitive towards all temperatures that aren’t like rain. This study was very important because it helps us understand part of the why on what we wonder about
