In Science class, Sara needed 8 test tubes for 3 different experiments. The first experiment required 2 test tubes and the other two experiments required the same number of test tubes. How many test tubes were needed for each of the other two experiments?

Sara has already used 2 test tubes for the first experiment.

She still needs 8 - 2 = <<8-2=6>>6 test tubes for the other two experiments.
Since the other two experiments require the same number of test tubes, she needs 6 / 2 = <<6/2=3>>3 test tubes for each of the other two experiments. Answer: \boxed{3}.

To find out how many test tubes were needed for each of the other two experiments, we can subtract the test tubes already used for the first experiment from the total number of test tubes needed.

Total test tubes needed = 8
Test tubes used in the first experiment = 2

To find the number of test tubes needed for each of the other two experiments, we can subtract the test tubes used in the first experiment from the total number of test tubes needed:

Total test tubes needed - Test tubes used in the first experiment = Number of test tubes needed for the other two experiments

8 - 2 = 6

Therefore, each of the other two experiments required 6 ÷ 2 = 3 test tubes.
