Dean owns a pet turkey named Gobbie. Gobbie is trained to come when Dean holds out corn and says "Here, Gobbie." Dean's mom says that Gobbie just wants the food and is not trained, just hungry. Dean believes that he has done a great job of training Gobbie. What would be the best way for Dean to prove to his mom that he has trained Gobbie?

• Call for Gobbie but do not hold up any corn

• Make hand gestures to Gobbie to see if he will come

• Have Gobbie watch videos of Dean holding out the corne

• Place the corn in a can and shake it when he calls for him

If a scientific experiment repeatedly gives the same results, the experiment is

• valid

• a law

• invalid

• being done by an untrained student

Why might a scientist repeat an experiment if she didn't make a mistake in the first one?

• To make more money

• To ensure that the results are consistent and repeatable

• To make sure to obtain expected results to match hypothesis

• To determine if any portion can be skipped and still get the same results

If an experiment's results are accurate, when the experiment is repeated by another scientist, the results

• should be similar to those obtained originally

• will be identical every time the experiment is repeated

• should be completely different for a different scientist

• should vary quite a bit because of the difference in time between the completion of the experiments

When an experiment is repeated and the new results are different from the original results, what could you assume to be true?

• The results from both experiments are worthless

• The first experiment's results are worthless and should be discarded

• The experimental design is flawed and the experiment should be discarded

• Neither test results are 100% reliable and additional experimentation is needed

Joe and Angie are studying how listening to music affects grades. Joe listened to music while he studied while Angie studied in silence. After two weeks, they took the same math test and Joe scored higher than Angie. They came to the conclusion that listening to music will improve grades. What comment would you make to Joe and Angie about their experiment?

• They should have tested more people

• Joe was already better at math than Angie

• This topic has already been studied before

• They should have chosen a different subject besides math
