Question
Select the statement(s) that are investigations based on scientific thinking.
Phillip broke a mirror and believes he will now have 7 years of bad luck. He tested this and created a tally sheet to keep his data. Every time something bad happened, he marked it as bad luck. When good things happened, he marked it as good luck.
Vanessa studied two hours before taking a math test. The content was easy, and she scored a 90%. She decided to only study two hours before taking tests in all her other subjects. She did well on some tests and not so good on others.
Victor tested the effect of breath-mints on soda. He chose 3 different types of soda. He used the same type of breath-mints each time. He conducted each test 3 times and recorded the height of the reaction.
Javier observed what his mom served for dinner each night for a week. He noted that in the morning when he wished he would not get vegetables on his plate, he still got vegetables. When he did not wish, he did not get vegetables.
Selena observed the tides for a week. She observed that there are two high tides and two low tides every 24 hours. She determined this is due to the gravity of the Moon as it revolves around Earth.

The statements that are investigations based on scientific thinking are:
1. **Victor tested the effect of breath-mints on soda. He chose 3 different types of soda. He used the same type of breath-mints each time. He conducted each test 3 times and recorded the height of the reaction.**
- This example demonstrates a controlled experiment with a clear hypothesis, variables, and systematic data collection.
2. **Selena observed the tides for a week. She observed that there are two high tides and two low tides every 24 hours. She determined this is due to the gravity of the Moon as it revolves around Earth.**
- This example involves observation, pattern recognition, and a scientific explanation of a natural phenomenon based on evidence.
The other statements (Phillip, Vanessa, and Javier) do not fully align with scientific thinking as they lack systematic methods or clear hypotheses. Phillip's belief in superstitions, Vanessa's assumption based on one experience without control of variables, and Javier's observational notes without a controlled experiment do not constitute robust scientific investigations.
