Science Map Review

Based on their observations, can the students correctly conclude that a chemical reaction occurred?

• No, because the metal strip was still visible

• Yes, because a new material of a different color formed on part of the metal strip

• No, because the solution stayed blue

• Yes, because the volume of the blue solution stayed the same

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 an experiment to test the effect of sunlight on the rate of photosynthesis in a plant. What would be your control variable?

• The type of plant used

• The amount of water given to the plant

• The amount of sunlight each plant receives

• The temperature of the environment

DOK Level 3: Strategic Thinking

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 are the convection currents in the student’s model different from the convection currents in Earth’s atmosphere and oceans?

• The warm air in Earth’s atmosphere and the warm water in Earth’s oceans sink instead of rise.

• The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below.

• Convection cells in Earth’s atmosphere and oceans flow in the same direction instead of opposite directions.

• Cold air in Earth’s atmosphere and cold water in Earth’s oceans are less dense than warm air and warm water instead of being more dense.

Based on the life-cycle information, which statement best describes the relationship between the nest fly larvae and the young birds?

• The larvae are prey for the young birds.

• The larvae are predators of the young birds.

• The young birds are hosts for the larvae.

• The young birds are consumers of the larvae.
