2. Observation:
• Mark the initial position of each larva.
• Note the direction and distance moved by each larva towards or away from the light source over a fixed period (e.g., 10 minutes).
• Observe any specific behaviors or patterns, such as rapid movement, turning, or pausing.
• Repeat the observations multiple times to ensure consistent results.
• Introduce variations, such as changing the intensity of the light source or using different wavelengths (colors) of light, to see how the larvae respond.
• Calculate the average distance moved and the percentage of larvae exhibiting positive or negative phototaxis.

• Direction of Movement:
• Positive Phototaxis: (Move toward the source of light)
• Negative Phototaxis: (away from the light source)
• Distance Moved: Note the distance and time  
• Behavioral Patterns: Example: Larvae exhibited rapid, straight-line movements towards the light source or away from the source)

 

Results:                1. ------ % of the larvae showed positive phototaxis moving towards the sight source.

2. ------ % of the larvae showed negative phototaxis moving towards the sight source.

3.  The average distance moved towards the light source was -------  cm, while the average distance moved away from the light source was -- ---- cm.
