DOK Level 1: Recall

In the context of thermal energy transfer, what does the term "convection" specifically refer to?

• The transfer of heat through electromagnetic waves

• The transfer of heat through direct contact

• The movement of heat through fluids caused by molecular motion

• The insulation of heat in a confined space

DOK Level 2: Skill/Concept

How does radiation transfer heat?

• Through direct contact between objects

• Through the movement of air or liquid

• Through electromagnetic waves

• Through the movement of atoms within a solid

If you were to touch a metal spoon that has been sitting in a pot of boiling water, you would feel heat primarily by which process?

• Convection

• Radiation

• Conduction

• Evaporation

DOK Level 2: Skill/Concept

Design an experiment to compare the conduction rates of copper, steel, and aluminum rods.

• Measure the temperature at one end of each rod after heating the other end.

• Place each rod in water and measure the time it takes to reach boiling.

• Heat each rod to the same temperature and measure the time it takes for each to cool to room temperature.

• All of the above

DOK Level 3: Strategic Thinking

Explain how the process of convection is used in designing heating systems for buildings.

• By ensuring that heat is radiated evenly throughout the building.

• By using insulated materials to prevent heat loss.

• By facilitating the movement of warm air from heaters and dispersing it throughout the rooms.

• By installing reflective surfaces to redirect radiant heat.

DOK Level 3: Strategic Thinking

Propose a method to demonstrate radiation using common household items.

• Use a flashlight to represent the sun and observe how light travels through space.

• Heat a metal rod and touch it to see how heat is conducted.

• Boil water in a pot and observe the steam to understand convection.

• None of the above

DOK Level 3: Strategic Thinking

Develop a hypothesis on how increasing the surface area of an object affects its ability to lose heat by radiation.

• Increasing surface area does not affect radiation.

• Increasing surface area decreases the rate of radiation.

• Increasing surface area increases the rate of radiation.

• Surface area has an unpredictable effect on radiation.

Investigate how different materials affect the convection currents in water by using colored dyes and timing how long it takes for the color to spread.

• Use glass, plastic, and metal containers filled with water and a drop of dye.

• Use the same type of container with different amounts of water.

• Use different heating sources for the same container.

• None of the above methods are appropriate.
