What is hydroponic farming?

300

When measuring a plant, you are using this type of observation.

What is a quantitative observation?

300

The height of the plant or how much it grows is called this variable?

400

Scientists use this tool to find the dependent variable.

What is a ruler OR a scale?

500

This farming system is the traditional way we farm and one of it's limitations is that it uses a lot of space.

What is conventional farming?
