Resting and Resting with just tail moving, resting on their sides, little tadpole not moving
Swimming- In circles, around edges of container
Social behavior- isolation in corners , social resting, bumping into each other, larger ones avoiding smaller one, chasing one another,
Feeding- pushing the food
Response to light-resting
Jolting- swimming in circles fast
Added Magnet- one tadpole slowly moving towards magnet, moved away
Added a third tadpole other larger ones are avoiding
Added other 2 other tadpoles, they are all keeping to themselves, one hiding under magnet
Time Interval Observation Over a Span of 5 Minutes
|Behavior||1 Minute||2 Minute||3 Minute||4 Minute||5 Minute|
|Rest With Tail Motion||x|
x= Number of tadpoles involved with a particular behavior at a time interval between 1-5 minutes.
-This was continuous sampling, and we had a pre-set time to observe in minute intervals.
|Pushing food around the dish
|Swimming fast around in circles
When dish was moved or touched, the tadpole would jolt away
Swam slowly around dish with no direction
|Not moving, in one spot
Resting with only the tail moving
|Would bump into others and then swim away
Would chase each other around the dish, sometimes after bumping
Will rest in one spot together
Question: If there are more tadpoles in the container are they more social with each other or do they try and stay isolated?
Hypothesis: Tadpoles are more social when they are in larger groups
Prediction: If tadpoles are more social when they are in larger groups, then they will have more interactions and be less isolated.
We started observing 3 tadpoles and they all seemed to be on opposite sides of the container isolating themselves. When we added 2 more, they had less space to swim around, therefore being forced to interact with one another (bumping, resting next to each other, chasing). This confirms that our prediction could be correct.
