in this experiment, 3 sets of plants were grown. one set had no light, one set had some light, one set had full sun. each set was given the same amount of water, the same temperature, the same soil and it was the same plant and same pot. in 21 days this is the amount of growth for each set of plants: the plants is no sun grew 7cm; the plants in some light grew 16cm; the plants in full sun grew 28cm.

The independent variable in this experiment is the amount of sunlight received by each set of plants (no light, some light, full sun). It is the variable that is intentionally manipulated by the researcher.
The dependent variable in this experiment is the amount of growth exhibited by each set of plants (7cm for no light, 16cm for some light, 28cm for full sun). It is the variable that is affected by the independent variable and is measured or observed to determine the outcome of the experiment.
To measure volume, a tool called a graduated cylinder or a measuring cup can be used. These tools have graduated markings that allow for precise measurement of liquid volume.
To measure mass, a tool called a balance or a scale can be used. These tools can accurately determine the weight or mass of an object.
To measure length, a tool such as a ruler or a measuring tape can be used. These tools have units of measurement marked on them to provide accurate length measurements.
To measure temperature, a tool called a thermometer can be used. It allows for the quantification of temperature in degrees Celsius or Fahrenheit.
