- 24. Multiple ChoiceI noticed that mold grows faster on bread on humid days. Which is the best hypothesis to test why that happens?If I leave dry bread and moist bread in bags for two weeks, then the moist bread will grow mold more quickly than the dry bread, because mold is a living organism, and organisms need water to survive.If I leave dry bread and moist bread in bags for two weeks, then the moist bread will grow mold more quickly than the dry bread.Humidity helps mold grow faster.
- 25. Multiple ChoiceThe cooler the temperature in a lake, the more oxygen the water holds. Daniel notices that he catches more fish in a lake that is cooler than 55 degrees. He wants to conduct a study so he can catch the most fish possible this year. Which one is the best hypothesis for this case.If I increase the temperature in a fish tank then more fish will reproduce because the amount of dissolved oxygen available is higher and fish spend less energy breathing in cooler water.If I decrease the temperature in a fish tank then more fish will reproduce because the amount of dissolved oxygen available is higher and fish spend less energy breathing in cooler water.If I decrease the amount of fish food I feed the fish in a tank, then more fish will reproduce because the amount of dissolved oxygen available is higher and fish spend less energy breathing.If I decrease the amount of fish food I feed the fish in a tank, then more fish will reproduce.
- 26. Multiple ChoiceKasey lives in Moab, Utah. She likes to mountain bike for miles and miles until she can’t bike anymore. She thinks that she can bike further when she drinks more than a liter of water before her bike ride. Please assist her in developing a hypothesis, so she can make the best of her future bike rides.If I drink more than a liter of water before I ride then I will bike further.When the body is dehydrated, metabolism slows down.If I drink Gatorade before I ride then I will bike further because when the body is dehydrated, metabolism slows down.If I drink more than a liter of water before I ride then I will bike further because when the body is dehydrated, metabolism slows down.
- 27. Multiple ChoiceJimmy likes to work with his friend Joe on 7th grade science class labs. However, he notices that he tends to get lower grades when he does work with Joe, because he and Joe like to talk about basketball and not science. He’s decided to investigate if his science lab grades are higher when he works with Joe or if they’re higher when he works with someone else. He has set goals to become a better student, so could you please help him write a hypothesis for his study?If I work with one student then my grade will be lower when the student is Joe.If I work with a team of several students then my grade will be lower when Joe is in the team because we spend little time working.If I work with one student then my grade will be lower when the student is Joe because we spend little time working.
- 28. Multiple ChoiceMelissa raises crickets at her pet store that she sells for reptile food. She thinks that crickets chirp more often when the temperature gets warmer. She decides to conduct an experiment to prove her theory. What is an appropriate hypothesis for this observation.Crickets will chirp less if their cage is cooler.If crickets chirp more then it is cooler.If I increase the temperature in the cricket's cage, then the crickets will chirp less because crickets seek the heat.If I decrease the temperature in the cricket's cage, then the crickets will chirp more because they have more energy in cold weather.
- 29. Multiple ChoiceThe first three steps of the scientific method are:data analysis, writing procedures, and making observationsmaking questions, forming a prediction, and experimentingmaking observations and questions, doing research, and forming a hypothesis
- 30. Multiple ChoiceWhy is doing research important to create a testable hypothesis?because research provides information relevant to our predictionbecause our hypothesis needs an explanationresearch is not necessary to make a hypothesis
