Question

lily is tending flowers in her garden. she notices that the bumblebees spend a lot of time eating from some flowers and less time eating from other flowers. she wonders what factors affect where the bumblebees choose to eat. she has the following supplies available:

• one purple bumblebee feeder
• one green bumblebee feeder
• nectar
• sugar water

using only these supplies, which questions can lily investigate with an experiment? select all that apply.

• do bumblebees eat more nectar from a green bumblebee feeder or a purple bumblebee feeder?
• do bumblebees eat more nectar or sugar water from a green bumblebee feeder?
• do bumblebees eat more sugar water from a red bumblebee feeder or a purple bumblebee feeder?
• do bumblebees eat more nectar from a purple bumblebee feeder when it is mixed with pollen?

Explanation:

1. For the first question: Lily has a green and a purple feeder, and nectar. She can set up the two feeders with nectar and observe bumblebees' preference. So this is investigable.
2. For the second question: Lily has a green feeder, nectar, and sugar water. She can put nectar and sugar water in the green feeder (one at a time or side - by - side in a way that's testable) to see which the bumblebees eat more of. So this is investigable.
3. For the third question: Lily does not have a red feeder (only purple and green), so she can't test this as she lacks the red feeder.
4. For the fourth question: Lily does not have pollen as a supply, so she can't test this as she lacks pollen.

Answer:

A. Do bumblebees eat more nectar from a green bumblebee feeder or a purple bumblebee feeder?
B. Do bumblebees eat more nectar or sugar water from a green bumblebee feeder?
