Question

Katherine wants to investigate if the time of day a plant is watered affects the growth of the plant. She hypothesizes that a plant watered in the morning will grow faster than a plant watered at other times of the day.

Identify the specific independent and dependent variables that will be involved in an experiment to test this hypothesis.
List at least five variables that should be controlled during the experiment. For each variable identified, give a specific suggestion for how it can be controlled during the experiment. Please help... i'm so confused

Answer 1

God this is confusing.. I get the Independent Variable and Dependent Variable. Independent is the one that never changes. Dependent is one that can be manipulated. The Dependent Variable would be the plants that get watered at different times of the day. I'm a bit confused on the Independent Variable though. :/

Answer 2

Ahhh:/ i'm just so confused. i'm gonna fail omg

Answer 3

Maybe the Independent Variable would be a plant that's... lets see, a plant that doesn't get watered at all? That still doesn't make any sense though.

Answer 4

Or, maybe a plant that's watered at all the period of time (Morning, afternoon, night, etc) But then to me that still doesn't make sense! Grr.

Answer 5

Independent= time of day watered
Dependent= Growth
Variables= Amount of water.
Amount of soil.
Sunlight
that's what someone told me

Answer 6

Ohh, now I see. Yeah, then, that seems right. For the examples you can just put like soil = x amount for x amount of plants and x amount of water for x amount of plants etc.

Answer 7

what example? i don't have to write examples lol

Answer 8

I meant the specific suggestion lol

Answer 9

Oooh lmao... but i need to List at least five variables that should be controlled during the experiment -_- fml
