Question

using only these supplies, which question can danielle investigate with an experiment? do squash plants grow larger if the seeds are planted in small pots or in large pots? if squash seeds and tomato seeds are planted with compost, which type of plant grows larger? do squash plants grow larger if the seeds are planted with compost or without compost?

Explanation:

To determine which question Danielle can investigate with an experiment, we analyze each option based on the idea of a controlled experiment (changing one variable while keeping others constant) and the implied "supplies" (likely squash seeds, pots, compost, etc., but the key is the variable being tested):

Analyzing Each Option:

1. "Do squash plants grow larger if the seeds are planted in small pots or in large pots?"

• This tests pot size, but we don’t know if Danielle has both small and large pots (the problem says "using only these supplies"—if supplies don’t include both pot sizes, this is invalid).

1. "If squash seeds and tomato seeds are planted with compost, which type of plant grows larger?"

• This compares two different plant species (squash vs. tomato). To test this, Danielle would need both squash and tomato seeds. The problem implies the "supplies" are likely focused on squash (since all other questions are about squash), so this is less likely.

1. "Do squash plants grow larger if the seeds are planted with compost or without compost?"

• This tests the effect of compost (one variable: compost vs. no compost) while keeping the plant species (squash) and likely pot size/other factors constant. This is a classic controlled experiment with a single variable, and it only requires squash seeds, pots, and compost (or lack of it)—so it’s the most feasible with typical "supplies" for a plant experiment.

Answer:

Do squash plants grow larger if the seeds are planted with compost or without compost?
