Alexia is testing the effect of adding salt on the conductivity of distilled water. To do this, Alexia took 5 beakers and filled them each up with 50mL of room temperature distilled water. She added 0g of salt to beaker 1, 10g to beaker 2, 20g to beaker 3, 30g to beaker 4 and 40g to beaker 5. She stirred each beaker for 10 seconds and then measured the conductivity.
What is the independent (testing) variable?
A Group of answer choices
B the amount of salt in each beaker
C the beaker with no salt
D the conductivity of the beaker
the length of time she stirred the beaker
