Take a battery from each different battery type (prefferably three). Leave those out in the same conditions as the ones being tested when the one being tested is determined "dead", take a voltmeter and compare the control battery with the tested battery.
The Expereimental group in science is the group that has a lot to do with the project.The control group is the group that has less to do with the project. pretty much what doesn't have to be used and what wasn't useful.
An observation from a science experiment.
A control group is the unaffected group in a science experiment.
Control in a science experiment means it stays the same and you don't do anything to it.
a control group is a sample that is treated like the other experimental groups except that the independent variable isn't applied to it
Test Group when you test a project with a "GROUP"
its means that you r going to be working in a group of people to do your science project
A group meeting is where everyone in a particular group meets up to talk about the project. This could be for a science fair project for example.
This would be 'the control group' which experiments are compared to.
control group are the ones that are not being tested. dependent variable is the hair growth.
Nothing.
Sure, but remember you will want to document your data and have a control group and non control group. State your hypothesis clearly and what you think will happen as a result of giving the nice caffeine.
