In this activity students will create a mathematical (graphing) model of the lunar phases. They will use metric measurement skills to determine percentage representation of moon phases and develop a graph of the lunar phase. Then they will analyze the graph to make predictions.
Student Learning Objectives:
• Measure accurately using a metric ruler
• Calculate percent of moon surface illuminated
• Organize and graph data
• Middle School Science (6-8) Next Generation Science Standards
o MS-ESS1-1. Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons. [Clarification Statement: Examples of models can be physical, graphical, or conceptual.]
• Middle School Common Core Math
o MP.2 Reason abstractly and quantitatively.
o MP.4 Model with mathematics.
o 6.RP.A.1 Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
o 7.RP.A.2 Recognize and represent proportional relationships between quantities.
o 6.EE.B.6 Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
o 7.EE.B.6 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
