What is the independent variable in the experiment?

A. lima bean

B. amount of water

C. plant growth

D. the material (cotton ball, soil, or gravel)

What is the dependent variable in the experiment?

A. lima bean

B. amount of water

C. plant growth

D. the material (cotton ball, soil, or gravel)

One control in the experiment is

A. The amount of water in each bag

B. the material in the bag (cotton ball, soil, gravel)

C. how much the lima beans grow

If Janessa is measuring the height of the plant, what type of data is she collecting?

A. Qualitative

B. Quantitative

What is the dependent variable in Janessa's experiment?

Amount of water added.

Seeds planted in each bag.

Plant growth measured over time.

Why is it important to measure growth every two days?

To track growth patterns and changes over time.

To change the materials if needed.

To add more water each day.

Based on Janessa's experiment, which medium is most effective for sprouting lima bean seeds?

Soil provides necessary nutrients for growth.

Cotton prevents adequate drainage for seeds.

No medium supports seed sprouting.

What is the purpose of using three different baggies?

To have backup in case of failure.

To compare effects of different materials.

To test only one material at a time.

What might be a limitation of Janessa's experiment?

Using sunlight as a variable.

Growth only measured at the end.

Too many materials being tested.

It uses only one type of seed: lima beans.

How could Janessa improve her experiment?

Test additional materials for better comparison.

Increase the amount of water in each bag.

Change measurement intervals to daily.

What conclusion can be drawn from the results?

Gravel is the best material for sprouting.

Cotton balls provide too much moisture.

Soil likely aids in optimal seed sprouting.

Differentiate between data collection in science and engineering.
