1. a student notices that plants near a window grow taller than plants placed farther from the window. what would be the next appropriate step in the scientific method?

• a. conclude that all plants need direct sunlight
• b. form a hypothesis about the relationship between light and plant growth
• c. publish the findings in a scientific journal
• d. move all plants away from windows

1. which of the following is not an example of technology used in scientific investigations?

• a. microscopes
• b. scientific theories
• c. digital sensors
• d. computer modeling software

Explanation:

11.

A graduated cylinder with water displacement is used to measure the volume of irregular - shaped objects. A triple - beam balance measures mass, a metric ruler measures length, and a thermometer measures temperature.

In scientific investigation, reliability means that an experiment gives consistent results when repeated under the same conditions. The identity of the scientist (b), the cost of equipment (c), or getting expected results (d) are not the definitions of reliability.

After making an observation (plants near the window grow taller), the next step in the scientific method is to form a hypothesis. Concluding (a) is premature without testing, publishing (c) is too early, and moving plants (d) is not the next logical step.

Answer:

b. Graduated cylinder with water displacement
