Science Help?????????????????????????
im doing an experiment on forms of hearing protection i had to put cotton wool in my ear and test how far the volume on a radio had to go before i heard it and do the same with ear plugs in then ear muffs that none i got all that now its asking for the control of the experiment which gives the baseline for comparison what was the control in this experiment??????????????????? also how could i have improved this experiment and made it more scientific?
control would be the experiment without using ear plugs….
to make it more scientific, u could use different kinds of earplugs…u could also make a chart showing the volume and the different earplugs used
