Which factor is the variable in this experiment?

• the type of bee
• the time of day
• the type of plant
• the color of the flowers

Which of the following hypotheses could be tested by this experiment?

• Honeybees prefer to visit rose plants
• Honeybees prefer to visit red flowers.
• Honeybees prefer to visit flowers in the morning
• Honeybees prefer to visit Portland rose flowers between 9 and 10

Which of the following is the BEST reason why the Portland rose plant is included in all of the groups to be studied?

• The type of plant is a constant (controlled variable).

• The experiment will test whether bees prefer Portland rose over other roses.

• An experiment should have more than one variable.

• The Portland rose is a very common plant.

Which of the following statements describes how temperature changes in the mesosphere?

• Temperature increases as altitude increases.
• Temperature decreases as altitude increases.
• Temperature decreases as pressure increases.
• Temperature does not change as pressure increases.

A research balloon took measurements at 23 km, 35km, 52km,73km,86 km, 92 km, 101 km, and 110 km. Which measurements were taken in the mesosphere?

• measurements at 23 km and 35 km

• measurements at 52 km and 73 km

• measurements at 86 km and 92 km

• measurements at 101 km and 110 km

During an experiment, the setup shown in the diagram is maintained for 72 hours. Which of the following is the most likely outcome?

• Beaker A will hold less water than beaker B will.

• The amount of water in beaker A and beaker B will stay the same.

• The amount of water in beaker A and beaker B will change by about the same amount.

• Beaker B will hold less water than beaker A will.

Look at the line graph.  Which statement is consistent with the line graph?

• The ability of air to hold moisture increases as temperature increases.
• The ability of air to hold moisture decreases as temperature increases.
• The ability of air to hold moisture decreases and then increases as temperature increases.
• The ability of air to hold moisture stays the same regardless of temperature.
