A study was created to test the effects of fear in children. The hypothesis of the experimenters was that if babies were exposed to fuzzy bunnies and at the same time a loud cymbal was struck close behind them, then that child would be afraid of all fuzzy things. Another group of children would be exposed to bunnies without any loud noises. The study was carried out as planned and as a result, hundreds of young children developed fear of all cute furry bunny rabbits. Dependent Variable:

Control Group:

Independent Variable:

Experimental Group:

Dependent variable: the children's fear of rabbits

Control: the group that was NOT exposed to loud noises

Independent variable: the loud noises

Experimental Group: the group that was exposed to loud noises

the answer for sodium is 0.186
