Question

kyle found speed of 5 rockets. some results were much different. how can he verify his results? he can ignore the different data. he can repeat his experiment with the same rockets. he can change his experiment. he can test again with cars instead of rockets.

Explanation:

In scientific experiments, to verify results when there are discrepancies, repeating the experiment with the same conditions (in this case, the same rockets) helps to check for consistency and accuracy. Ignoring different data is bad scientific practice. Changing the experiment or using different objects (cars instead of rockets) won't verify the results of the rocket - speed experiment.

Answer:

He can repeat his experiment with the same rockets.
