Two scientists are conducting similar experiments. The results of their experiments are very different. Which of the following would be best for the scientists to do next?

• Assume that both scientists are correct

• Change the experiment that is incorrect

• Redo both experiments to see if they have very different data again

• Determine that both scientists are incorrect.

Mandy wanted to see if a new, environmentally-friendly pesticide will prevent insect damage to tomato plants. After making her hypothesis, she conducts her experiment. She treats five tomato plants with traditional pesticide and five with the new pesticide. Mandy also leaves five plants untreated as a control. She makes careful notes of how she set up her experiment and then records her data about all of the plants. Why is it important for Mandy to record her procedures and data accurately?

• So that her hypothesis will always be correct

• So that she can look intelligent when she presents her data

• So that society does not wast money on buying pesticides that do not work

• So that other scientists can replicate the experiment and make sure the results are correct

A scientist makes a major new discovery that provides some evidence that a different approach to gene therapy might be helpful. Which of the following should happen next?

• Her work must be repeated by other scientists

• Her work must be published on the internet

• Her work should be used in treating patients immediately
