教學目的 To explore the pond habitat through field and lab experiences. Students will know living things are made-up of cells, how living things interact with their habitat, and why they are important.
教學內容 1. Students are introduced to John Heinz NWR. They learn what a National Wildlife Refuge is and the 5 different habitats that we have. They are told they will become scientists that will study the pond habitat for their field trip. Students discuss what they know and what they want to know about ponds. Questions such as the following can be used to stimulate conversation. a. How do you know that something is alive? What to living things need to survive? b. What are the living and non-living things in a pond? c. What kinds of creatures or things live in a pond? d. What do you think is the biggest creature to live in a pond like this one? The smallest? What does a pond food web look like? e. Can you see any living things in the water? If so, what? f. Do you think that anything could live in just a single drop of pond water? Why or why not? 2. Students walk out to pond to make observations (Date/Time, Weather, Location, Plants, Animals, Etc.) and collect water samples. Students bring water samples back to lab. 3. Students are given a quick tutorial on how to use a microscope that includes the parts and how to use it as well as how to make a slide. This is completed on a microscope that is projected on a tv so the class learns together how to identify a few micro-organisms. 4. Students work in small groups to make slides and observe a drop of water at 40x and 400x magnifications). Observations should be kept in their student journal. a. Is there anything in the water? What do you see? b. Once you see a living thing, follow it closely and sketch it in your notebook. Draw some of the paths it takes as it moves across the field of your microscope. c. Sketch the shape of the kind of living organism you seem to see most often in your field. d. Do all the organisms you see move in the same way? In what different ways do they move? e. How many different kinds of organisms have you seen? If you had to name these organisms in a way that describes them, what names would you give them? Compare the organisms that you see with the organisms on the pond life chart. f. Do you see something in the field that is not moving? What could this be? g. Discuss the role of these organisms in the ecosystem? Why are they important? What would happen if they weren’t there? 5. Students share observations and what they learned with the class. 6. ***Variations – If time permits, students can sample water from different habitats on the refuge (pond, creek, marsh, and even a puddle!)
