Key Idea.
Section 1
Planning an Investigation
Real science isn't just looking; it is looking with a purpose. A scientific investigation starts with a clear plan.
This plan decides what data to collect (like the time of night and direction) and how to record it. A good plan ensures that the evidence collected is useful for answering a specific question.
Section 2
Organizing with Data Tables
To find patterns, scientists must be organized. They use a data table to record their observations systematically.
A data table has columns and rows to keep information tidy. Instead of scribbling random notes, a scientist fills in the table every night. This systematic collection makes it easy to compare data from different dates.
Section 3
Finding the Evidence
Once the data is organized in a table, the patterns become clear. The table acts as evidence.
For example, a data table might show that a specific star is getting lower in the sky each night at the same time. This evidence proves that the stars are shifting, supporting the idea that Earth is moving in its orbit.
