True or False? Because students will often work in teams during lab, it is appropriate for a student to copy homework answers from their team members.

False

Of the following, which are required for personal safety in lab? (Circle the letter of all cor- rect answers.)

Make an Observation Ask a Question Form a hypothesis

Which of the questions below can be answered scientifically? (Circle the letter of all correct answers.)

How far can a kangaroo rat jump?

What do you do if the fire alarm goes off but you don't smell smoke? (Circle the letter of all correct answers.)

The morning before a Biology 1 midterm, half of the students in a class were given plain water for breakfast while the other half were given an energy drink. The average exam scores of the two groups were compared to see if the type of drink has an effect on the students' grades. What is the dependent variable in this study? What is the independent variable in this study?

In this case, the dependent variable is the grade obtained by every student after drinking the given drink. In this case, the researchers are manipulating which type of drink is to be given to each student. So, the type of drink is the independent variable.

Which variable is the one that is adjusted by the experimenter? (Circle the letter of all cor- rect answers.)

Independent variable

A good hypothesis includes which of the following? (Circle the letter of all correct answers.)
