Snail Matriculation Lab

Introduction

Research by Seuffert and Pablo (2013) supports that there are many contributions that affect the lifecycle of a snail; their growth, feeding, crawling, reproduction and survival depend on temperature. In knowing this we wanted to test the movement of snails in different temperatures within different populations (1 snail, 5 snails, 10 snails). Temperature effects all physiological processes but is still not explained. The body temperature is linked to the habitat in which the snail lives in, which is always changing. (Chapperon et al. Laurent 2011) So, we added another variable. We wanted to see if it

We predict that the larger the population and the higher the temperature, the movement there will be within that trial. In these four experiments we determine the effects water temperatures has on snails and longevity for the snails to separate from each other in larger groups.

Methods

Four experiments were conducted to determine how fast snails would move in 1 minute at different temperatures based on their population size. In this experiment each member of the group (4 members) received 3 groups of snails. The groups consisted of 1 snail, 5

The snails were not fed at the same time and were not fed the exact same amount in all groups. Also, when taking the recordings of each group they were each done at different times. All members should have taken their readings at the exact same time every other day. This may have affected our results if the readings were taken after feeding or if they were taken in the morning or in the night. Within these four experiments we cannot prove our hypothesis. Although in the first three experiments we had positive results to support our hypothesis experiment four contradicted it. There was in no way that we could prove that the temperature of the snails environment effects their movement depending on if they were in small or large
