Canopy Cover Impact on Stream Oxygen Levels: An Adventure in Scientific Inquiry

Explore how canopy cover affects dissolved oxygen in streams through lab experiments and field observations. Adventure scientists Mary and Annie conduct tests at different sites with varying canopy covers to gather data. This presentation serves as a sample of the Scientific Process for 6th-grade science students, guiding them in testing water from the Woodland Monitor Well. Follow their procedures and embark on a learning journey to understand the relationship between canopy cover and oxygen levels in small streams.

  1. Adventure Learning 2014 The Mary And Annie Show

  2. Inquiry • Does canopy cover affect the amount of dissolved oxygen in a small stream?

  3. Hold onto your shorts and tevas… • We think the amount of canopy cover will change the dissolved oxygen levels in a stream.

  4. Procedure • Select 5 sites. • Estimate canopy cover and take a picture. • Use Lab Quest probes to take air temperature.

  5. Procedure (continued) • Lab Quest probes read water temperature AND dissolved oxygen level.

  6. Procedure (continued) • Use the CHEMets kit to take a 2nd dissolved O2 reading.

  7. Site #1: canopy cover: 98% • Left Bank: highly vegetative • Right Bank: erosion, moss, plants, undercut

  8. Site #2: Canopy cover: 60% Left Bank: grassy and undercut Right Bank: rocky, flat, some plants

  9. Site #3: Canopy cover: 15% Left Bank: undercut, erosion Right Bank: stone, rocks, vegetation

  10. Site #4: canopy cover: 50% Left Bank: erosion, rocky, some vegetation Right Bank: ferns, debris, rocky

  11. Site #5: Canopy cover: 90% Left Bank: erosion, root balls, moss Right Bank: erosion, logs, moss

  13. We were right!

  14. This presentation will be shown to 6th grade science students to as a sample of the Scientific Process. They will be expected to follow the same procedures when testing water from the Woodland Monitor Well.
