Question

Why would you not test the affect on the amount of water and temperature on the germination of seeds at the same time pleeeaseee help me

1 Answer

  • In this case, there are 2 variables: 1. the amount of water & 2. the temperature. Only 1 variable can be tested at a time, while the other must remain a constant. Otherwise, any changes seen in germination can't be attributed to to the amount of water or the temperature.There can only be one variable tested for and all else must remain constant.
