1. CHANNELS ON MARS 5-E Activity Module Learning Through Inquiry

2. What is THEMIS? THEMIS stands for Thermal Emission Imaging System and is a type of camera on board the 2001 Mars Odyssey spacecraft. It contains two independent multi-spectral imaging sub- systems: a 10-band thermal infrared imager (IR), and a 5- band visible imager (VIS)

6. How did these channels form? What other features do you see in this 3-dimensional computer- generated image? 3D Image: SEMSZ9474OD, East of Valles Marineris, HRSC image, ESA/DLR/FU Berlin (G. Neukum), 14 January 2004. http://www.esa.inthttp://www.esa.int.

8. This cliff has some small channels forming on its slope. How might These have been made? Can you also see a landslide? Newton Basin, Mars http://antwrp.gsfc.nasa.gov/apod/ap030205.htmlhttp://antwrp.gsfc.nasa.gov/apod/ap030205.html

9. Engage: Prior Knowledge Activity Use your KWL table with your partner to brainstorm your ideas and questions. What do we know about channels on Mars? (what they look like, how they are made, when were they formed?) What questions do we have about channels on Mars? How might channels on Mars be different from channels that are formed on Earth?
