In this step, it is important that you collect and compile the data for all images observed. For this CRATER COMPARISONS activity you will likely have a master data table for each planetary world you are investigating. Each table should be structured in an identical format.

1. MASTER DATA TABLE:

For this page on your own TEAM Wiki it is recommended that you post your finalized master data table(s). One option is to take a screen shot of your data table and insert those images on the page. Another option is to upload your finalized excel spreadsheet(s) of each master data table.

Additional information:
It is important to log your data consistently. Notice on the data table provided, the column headings provide specific details as to the information you should log. For example, the column heading for crater diameter states "Crater Diameter (km)". This means that when you log the diameter of the crater you only need to include the actual diameter as a number. You do not need to include km with each entry. By including (km) in the column title, it signifies that all diameters logged are in km. crater diameter should be logged in kilometers (km). This will allow you to later sort information on your spreadsheet if desired.

The choices listed for the visible observations are very specific choices that will also allow you to make common comparisons among Earth craters as well as your observations of craters on other planetary worlds. Make additions or changes as you see fit...just make sure you are consistent as you log your data.

  • Collect and compile additional data on the provided excel spreadsheet and/or on the PDF file (suitable for printing and writing in your information). There is a separate file for your data collection of impact craters on Earth and other planetary worlds.
  • Make changes/adjustments as you see fit.
  • Be sure to log your data consistently.


2. NEW DATA REQUEST INFO:
This only applies if you wish to expand on this research investigation or if your class has initiated their own unique research investigation. In these cases, you have the opportunity to put in a request for new data to be acquired from by astronauts on the International Space Station.

Information about submitting New Data Requests is available at: http://ares.jsc.nasa.gov/ares/eeab/DRF.cfm
