Step-by-Step Procedure

  1. 1

    Step 1: Mix sugar and water to create a nectar solution.

  2. 2

    Step 2: Split the nectar into three cups, adding different food coloring to each.

  3. 3

    Step 3: Fill butterfly feeders with each colored nectar.

  4. 4

    Step 4: Place feeders in a butterfly-friendly area.

  5. 5

    Step 5: Observe and record how many butterflies visit each feeder daily.

  6. 6

    Step 6: Change the position of feeders every two days to avoid bias.

  7. 7

    Step 7: Continue the observations for two weeks.

  8. 8

    Step 8: Analyze which nectar color attracts the most butterflies.

Expected Results

Butterflies are expected to show preference for certain nectar colors, likely favoring the sweeter or more vibrant options.

Variables

Independent Variable

Nectar flavor

Dependent Variable

Number of butterfly visits

Controlled Variables

Butterfly species, Feeder design, Location
