Final Observations and Disassembly of E-Column
DAY 3May 10-11
Type of Chamber Measure/Count Other Instructions
Terrestrial Chamber
1. Dry Mass of filter material and soil
2. Dry Mass of plants
1. Measuring Dry Mass. Place materials in plastic bag. Let it dry. Measure mass.
2. Calculate change in mass. 3. Place materials in proper bins.
Aquatic1. Volume of water2. Mass of aquatic plant3. Number of organisms/fish
1. Place measured water, aquatic plants in bucket/basin.2. Fish to be released in the pond.3. Dead snail goes with decomposition
material
Decomposition1. Fruit peeling/paper/plastic
* If materials cannot be recovered, then observe for signs of decomposition (qualitative).
1. Measurements done outside of classroom. 2. All materials to be weighed need to
be in sealed plastic bags. 3. Return decomposition material to
our big decomp. bin (plaza level).
Note: You are responsible for completing the tasks for your assigned chamber. Wear safety gear (apron, masks, safety glasses, gloves).
Summary of Observations Interpretation
Relate to Law of Ecology
What data can you graph?
Growth of plant (TC) pH, temp, water (AC) Temp (DC)
A. Guidelines for Video Journal
1. Intro:
State the aim/purpose (question)Describe the set-up (germination, #of seeds, mass measurements, filters, chambers, identify biotic & abiotic factors)
2. Log & Analysis
Summary of observations (daily/weekly/highlights)Connection of observations to 4 Laws of EcologyData table & graph (connections)
Total time: 5 – 7 minutes
B: Guidelines for the Individual Diary•Data tables/graph (growth rate, pH, masses [soil, water volume, aquatic plant, snail/fish], temperature)•Labeled diagram of the e-column•Predictions/Questions/Curiousities
Timeline (May 14-18)
DAY 1- Analysis of data Making the video
DAY 2- Completing the video
