It happens to be noon. In this project, as students study the rotation and revolution of the earth, they begin to see patterns in numbers and to view the patterns in terms of a mathematical function. Some see the pattern graphically, while others use formulae. Students become acquainted with the idea of comparing their results to a standard measurement in order to calculate percent error. As an introduction to the idea of technology, there are in-class discussions about what it means to invent something that meets a need, works consistently, is calibrated, can be used by others, and is somewhat resilient.
Students discuss the benefits and pitfalls of certain everyday connections.
This project is designed to be a student-centered activity based on inquiry and constructed knowledge. Students participate in whole-class discussions, partner and team cooperative learning groups to experience a variety of learning styles. Mini-lessons on graphing and the scientific importance of minimizing variables may be used to guide the whole class. Some groups may need short lessons on calibration of instruments. Students should receive the type of instruction they need to achieve the final goal.
