1. dr. bowser was reading about another scientists research in a science journal. he plans to do these experiments himself to see if he gets the same results.\treplication\tanother scientist is doing the experiment
2. mulan goes to the saint johns river every week for 4 weeks and collects 5 samples of water to test the ph.\trepetition\tmulan is repeating her own experiment
3. the huns contact mulan to get her procedure so that they can check her results.\treplication\tanother group is doing mulans experiment

Explanation:

1. Dr. Bowser is another scientist doing someone else's experiment, so it's replication.
2. Mulan is repeating her own water - pH testing experiment, so it's repetition.
3. The Huns as another group are doing Mulan's experiment, so it's replication.
4. Jazzy as another person is doing Jordin's cookie - baking experiment, so it's replication.
5. Mike is repeating his own rat - maze experiment, so it's repetition.
6. Brayden is repeating his own golf - ball dropping experiment by dropping each ball more times, so it's repetition.

Answer:

2. Repetition, Mulan is repeating her own experiment
3. Replication, Another group is doing Mulan's experiment
4. Replication, Another person is doing Jordin's experiment
