- Snail habituation- Core Practical
- Variables
- Independent
- Poking the snail in the eye stalk
- Dependent
- How long it takes for the snail to retract and re-emerge
- Control
- Snail- Species and age
- Each snail will have different reaction times
- Outside threats to eye stalk
- Snail could respond to other stimuli
- Handling history
- Snail could already be habituated to stimuli
- Same cotton bud
- a different bud could lead to a different reaction
- Poking in the same place
- Poking in a different place could create a different response
- Snail- Species and age
- Independent
- Equiptment
- Snail
- White tile
- Cotton bud
- Water
- Stop watch
- Method
- 1. Collect a snail and place it on the white tile
- 2. Dampen the cotton bud with some water
- 3. Touch the snail on the eye stalk
- 4. Start the stop watch at the same time
- 5. Measure the time it takes for the snail to retreat into its shell and emerge
- 6. Repeat the experiment until the snail does not retreat into its shell
