How would you use the scientific method to determine the relationship between the mass of an object and its acceleration due to gravity?

• Calculate the force on different masses and measure the acceleration

• Drop objects of different masses from the same height and time their descent

• Increase the mass of an object while keeping the force constant

• Keep the mass constant and vary the force applied

Design a model to demonstrate how Earth's systems (geosphere, hydrosphere, atmosphere, and biosphere) interact to affect climate. Explain the role of each system in your model.

• Focus only on the atmosphere and its gases, ignoring interactions with other systems.

• Show how volcanic activity (geosphere) affects atmospheric conditions and influences ocean currents (hydrosphere).

• Model only the biosphere's impact on the atmosphere through carbon dioxide production.

• Isolate the hydrosphere and examine its effects without interaction with other systems.
