Garbology (Grade 6)

​​​​​​Garbology 101 combines archaeology and environmental science to encourage students to explore what choices people make about garbage. By examining how the past decisions of the Ohlone, Spanish, and early Americans impacted the Presidio over time, students are encouraged to reflect on how their present actions will impact the future. Through this program, students participate in the following activities:

  • Archaeology Lab visit - Students will visit a real archaeological lab and learn about the profession and process of archaeology.
  • Archaeobotany - Students are introduced to flotation, a scientific method of extracting botanical materials from soil. After performing flotation, students examine the seeds to learn that even without a lot of artifacts, archaeologists can learn a lot about the way people lived in the past.
  • Compost excavation and landfill examination - Students will investigate the process of decomposition by digging through mini simulation compost bins and examining simulated landfills, both filled with common materials from a typical student lunchbox. Comparing their compost results with their landfill results, students analyze why it is important to sort their trash in different bins.
  • Do One Thing - The program concludes with a group discussion about what choices students can make to influence the impact that their garbage has on the future.
