Which best describes a characteristic of the jet stream?
It is a band of high speed winds high in the atmosphere that forms a boundary between a cold air mass and a warm air mass.
It creates the high winds around the eye of a hurricane.

The class is working with classes in other schools in Jacksonville to investigate the amount of rainfall in different parts of the city. Each class has the same type of rain gauge and the same type of data chart to use to record the rainfall each day.
What is another important step for all the classes to include in their procedure?
Put the rain gauge in a grassy area at each school.
Use the same color pen to record the rainfall data.
Put the rain gauge next to the building at each school.
Use the same schedule for measuring the amount of rainfall.
What is one way that a fellow scientist can confirm that an experiments works and should be accepted?
They can replicate the experiment and see if they get the same result.
They can change the variables of the experiment and change the results.
They can keep the variables the same but use different tools to measure the data.
They can conduce a different experiment and show the different results.
Student’s in Mr. Ace's science class each exercised different amounts. After, they measured their resting heart rate. The data is below.
What conclusion can be made?
Exercising fewer hours a week will decrease the students' heart rate.
Heart rate remains unchanged regardless of how many hours of exercise.
Students who exercise more hours a week have a higher resting heart rate.
Increasing the amount of hours exercised will lower the students' heart rate.
Ms. Giannone divided her class into two different groups. Each group received a toy car. The groups were asked to measure its mass on a balance and determine the time it takes to travel down a ramp. Below are their methods and results.
Which statement below best compares the methods and results obtained by the two groups?
Group 1 and 2 had similar results. This shows that they both accurately followed the procedures.
Group 2 had the most accurate results because their time was less than the time recorded in Group 1.
Group 1 did not have accurate results because their time was more than the time recorded in Group 1.
Group 2 had different results because they did not follow the procedures accurately as the teacher explained.
During the nineteenth century, biologists found similar fossils in South America and Africa. The scientists theorized that a temporary land bridge between South America and Africa which allowed ancient species to move between both continents. In the twentieth century additional evidence showed that South America and Africa were once part of the same larger continent and that there were no land bridges between them. Which statement below best describes what biologists should do with this the new geological finding?
Biologists should update the theory due to newly found evidence.
Biologists should reject the geological findings since it conflicts with the current theory.
Biologists should update the theory because of the newly found evidence and reject any newer information.
Biologists should reject the geological finding because they cannot change their theory based on new information.
What is the significance of sharing scientific findings?
It allows others to learn from the research, replicate studies, and build upon existing knowledge.
It helps in securing funding for future research projects.
It reduces the time taken for research to be published.
It ensures that only the original researchers benefit from their work.
