Write A Hypothesis about water
If we didn’t drink water for 3 days we would be dehydrated because our bodys would use the water in our systems to move and sweat. Without the refill of water our bodys would became severely dehydrated and wouldn’t work well.
Independent and Dependent of experiment
The Independent would be drinking water the Dependent would be the bodys reaction to having or not having that water.
Control group for water
The control group would be a person who is normally drinking water and is not going through the experiment
Why is a control group important
A control group gives data that you can compare with two the experimental data. With out the control group we would not know if the experiment worked or not.
What would be a good control group
A good control group is a group that is not affected by the experiment. If there was a species and they wanted to determine what affects purple juice has on them they would need a species of the same kind to not have any purple juice then they could compare the data.
Error bar length and overlap
the length of the error bar determines how accurate the data is if something overlaps then they’re closer in comparison than something that dosnt.
In an experiment about if birds will turn blue if given blue juice what is the independent and dependent variables.
independent blue juice dependent blue birds
If there was a group that didn’t get anything what are they called
control
what is an bar Error
It is a way to determine if data is accurate by taking the margin of error and analyzing it with others.
What does sd stand for
standard deviation
