I was selected to participate in a week long Space Science Workshop at the observatory. I was excited to attend because it was my first time to travel to the area. I learned many fascinating things about space and activities to share with my K-4th graders in the science lab at Samuel W. Houston Elementary School in Huntsville, TX. My favorite experiment was when we proved that the Earth is moving not the Sun by the use of sidewalk chalk shadow people. I still use this experiment today with my students. Thank you so much for inviting me to participate in a world of space science in the great outdoors.
