SARAH'S ZOO CREW PROJECT
Ask a question: What water out of tap,salt,and creek has the best ph level for a tadpole to live in?
Collect Information: Tadpoles prefer a ph level 8.0
Hypothesis:I think that the creek water will work best for the tadpoles because a creek is the only place I ever see them.
Control group: how deep the litmus paper is in the water Independent Variable: what water group has the best ph level for a tadpole Experimental Group: different water
Dependent Variable: the ph level
Materials and Methods:
1- answer the questions
2-test each type of water 2 times
3-make sure you are correct by testing the water for a third time with a thicker litmus paper
I hoped to learn what type of water tadpoles lived in. I thought that the ph level would be the closest in the creek water because this is the only place I see them. I need to do tests with tadpoles to learn more
