Hydroponics vs Conventional Farming
A way of growing plants without soil, using water mixed with nutrients.
What is hydroponics?
Using your senses to notice details or gather information.
What is a qualitative observation?
When measuring the amount of sunlight, you are using this variable?
What is a dependent variable?
Working well without wasting time, space, or resources.
What is an efficient?
This is a type of question that you can do an experiment with.
What is a testable question?
In hydroponics, we put this into the water instead of using soil.
What are nutrients?
This observation includes numbers or measurements. Example: The plant is 10 cm tall.
What are quantitative observations?
The object or thing that changes in an experiment is called the ____________variable?
What is an independent variable?
A group of parts that work together as a whole.
What is a system?
This is what scientists gather when conducting an experiment.
What is data?
This farming system uses less water, less space, and allows plants to grow year-round.
What is hydroponic farming?
When measuring a plant, you are using this type of observation.
What is a quantitative observation?
The height of the plant or how much it grows is called this variable?
What is the dependent variable?
The problems or weaknesses of something.
What are limitations?
Scientists use this tool to weight objects
What is a scale?
This farming system needs technology and equipment and can be expensive.
What is hydroponic farming?
When describing a plant as 3 inches tall, soft green leaves and a furry stem, what kind of observation are you using?
What are qualitative and quantitative observations?
This variable is on the x-axis of a graph.
What is the independent variable?
When we put this in the water, it makes our plants grow healthy and strong.
What are nutrients?
Scientists use this tool to find the dependent variable.
What is a ruler OR a scale?
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?
This observation describes qualities (color, shape, smell). Example: The leaf is dark green.
What is a qualitative observation?
This variable is on the y-axis of a graph.
What is an dependent variable.
Supplies or materials used to meet needs (like water, land, or money).
What are resources?
Scientists use this to display data, see patterns and compare results.
What are graphs?
