Mineral Fingerprinting Audio Files

Task 1: Compare Leaf Sample Spectra

Youth first listen to audio files of spectra for plant leaves here on Earth to try help distinguish differences between samples. Sample 1 is from an Aspen tree in the summer (green) and the second sample is from an Aspen tree leaf in the fall (yellow).

Task 2: Learn the Mineral Fingerprinting Sample Audio Files

Youth first listen to audio files of spectra for 6 known minerals. Then, based on the audio files, they identify unknown minerals at 4 potential landing sites on Mars (Gale Crater, Iani Chaos, Jezero Crater, and Nili Fossae).

Known Mineral Audio Files

Play these audio tracks. Listen for differences between the files.

Gale Crater Unknown Mineral Audio Files

Play these audio tracks. Try to identify the minerals by comparing them to the known mineral audio files.

Iani Chaos Unknown Mineral Audio Files

Play these audio tracks. Try to identify the minerals by comparing them to the known mineral audio files.

Jezero Crater Audio Files

Play these audio tracks. Try to identify the minerals by comparing them to the known mineral audio files.

Nili Fossae Audio Files

Play these audio tracks. Try to identify the minerals by comparing them to the known mineral audio files.

End of Activity Reflection

Today, we identified minerals at potential landing sites on Mars. Which site do you think has the most interesting minerals?

Key Take Away

We can use data from known samples of minerals on earth to help identify minerals on other planets. Data can come in multiple forms, including audio, visual, and others.
