4 class periods of 60 minutes each
This is a field trip activity, our school has wetlands nearby, any other distinct ecosystem would suffice. Students will gather quantitative and qualitative data to describe this ecosystem.
- CBL units
- temperature probes
- ph paper
- field guides
- pond water tour test tabs
- dissolved oxygen
Student Prior Knowledge
Students should understand biotic, abiotic, relationships between living things, the difference between quantitative and qualitative data.
Hook: Have a picture of the wetlands on the overhead. Tell students they will be taking a series of field trips to research a hypothesis.
- Indicate that we will be collecting both quantitative and qualitative data for the biotic and abiotic factors of this ecosystem
- Ask the students to brainstorm at their tables a hypothesis they wish to test. Ex. If water is in the stream, then it will have more microorganisms.
- Have student write hypothesis on the overhead or whiteboard.
- Talk about sample size (it will be small so our results will not be extremely meaningful)
- Divide students into groups and have them brainstorm how they will collect their data. Make sure they know what equipment will be available to them for their use. They should write down their procedures and show them to you.
- Collect data 3 times at the .
- Have groups prepare their data for the class and present data. You may want to have them make computer generated graphs and tables
- Have students summarize data findings individually
- They should write a brief conclusion for this lab.
