STUDENT INSTRUCTION AND ANSWER Activity 3: Concept Application-
Using The Drake Equation = R x fp x ne x f1 x fi x fc x L In
Activity 2, we estimated the number of students that had
particular characteristics. In this activity, we will use the
same estimation techniques to discover the number of existing
extraterrestrial civilizations that possess the technology to
communicate beyond their home planet. Your task is to complete
the table below and use those values to solve the Drake Equation
in order to estimate the number of intelligent civilizations in
the Milky Way. You might wish to review the Drake Equation
Background Information Sheet before making your estimation.
After you make the calculation, answer the reflection questions.
R - Number of target stars in the galaxy that: - are second
generation stars with heavy elements - are hot enough to have a
large habitable zone - have a long enough lifetimes for life to
develop - Fraction (percentage) of those stars with planets or
planet systems. -Number of "Ea
