Grade 8 Quick Quiz: Light, Albedo, Measurement, and the Water Cycle
Description
A 5-question quiz on visible light and color, albedo, SI vs US customary units with a conversion, key water cycle processes, and Earth's usable water.
Learning Objectives
-
Explain that white light contains all visible colors, objects appear colored due to selective absorption and reflection, and darkness is the absence of light.
-
Define albedo and predict that different surfaces reflect and absorb different amounts of light.
-
Describe why SI units are used in science and convert US fluid ounces to milliliters using a provided conversion factor.
-
Match key water cycle process terms to their definitions.
-
Recognize that most of Earth's water is not directly usable for drinking, agriculture, or industry.

Use the notes and diagrams below as needed. Answer each question by choosing the best option.
Albedo is a measure of how much light a surface reflects. High albedo means lots of reflection. Low albedo means more absorption and less reflection.
Imperial (US customary) units are used in everyday life in some countries (inches, feet, fluid ounces). SI units are the standard units used in science worldwide (meters, liters, grams). Scientists use SI because it is consistent, shared internationally, and based on powers of 10, which makes conversions and calculations simpler and less error-prone.
Most of Earth's water is saltwater. Only a small fraction is freshwater, and much of that freshwater is locked in ice or stored underground.
Assessment Questions
5 questionsA prism can split white light into the visible spectrum (ROYGBIV). Which statement is most accurate? (See Diagram C-002 if helpful.)
Albedo is a measure of how much light a surface reflects. Fresh snow can cause snow blindness on a sunny day. Which explanation best connects snow blindness to albedo? (See C-003 and Diagram C-004 if helpful.)
Imperial (US customary) units are common in daily life in some places, but science uses SI units because they are consistent worldwide and easier to calculate with. Use the conversion chart: 1 US fluid ounce (fl oz) = 29.6 milliliters (mL) (rounded). (See C-005 and Diagram C-006 if helpful.)
A bottle holds 10 US fluid ounces. About how many milliliters is that?
Match each water cycle term to its correct definition. (See Diagram C-007 if helpful.)
The vast majority of Earth's water is NOT usable for drinking, agriculture, or industry. (See Callout C-008 if helpful.)
