The Educator Guide has a script, materials list, and prep directions. Be sure to have it open and ready to help guide you through every activity.

• If you have not already completed the prep for Science Series Activity 1, please refer to the S1 card for preparation.
• Revisit the PLANETS Science Series guide if its been a week or more since you completed a Science Series activity.
• For this activity you will need Science Notebooks for each youth plus Data Packets and Mineral Data Sheets for each group.

Provides opportunities for youth to identify minerals that indicate past water or volcanism at each of four landing sites.

• Consider showing one or more of the below videos to youth to review the concepts.
• "Spectrum" is singular and "spectra" is the plural form of the same word.

Science Snippet: Build your content knowledge to help answer youth's questions.

Today we investigated spectral graphs for minerals that indicate past water. Spectral graphs reveal different minerals because of how they absorb and reflect light.

We can identify minerals on Mars by looking at graphs of the light they reflect created by remote sensing technology (spectrometers).
