End of Year Science Review

The types of small organisms that live on the bottom of streams can be good indicators of water pollution. The table below groups some organisms by their tolerance of pollution.

A certain stream that was historically clear and clean has become increasingly polluted with fertilizer waste over the years. As a result of this pollution population of Sow bugs, Dragon flies and Midges will decrease.

• True

• False

• None of the above

• I have no idea

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.

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
