Monitor plastic pollution in Alamitos Bay and find out how environmental conditions influence the flow of plastic through the environment.
Grades 4 and up
Time Needed 30 to 60 minutes
Format Suitable for group or individual learning
– Trash Cam LIVE – Science Notebook – Google Doc
Purpose and Context
Why monitor trash floating through a bay? Bays, wetlands, and other coastal habitats are critical for the health of marine ecosystems. Many species use protected coastal areas as places for their young to grow up. By helping us monitor trash in Alamitos Bay we can better understand how plastic pollution might be impacting this ecosystem, and how to protect it.
Prepare Before class, print copies of the Trash Cam LIVE – Science Notebook – Google Doc or upload it to your LMS.
In class Students observe the Trash Cam LIVE for a total of 10 minutes. Ask them to also read through the information about the Trash Cam for more information about where it is installed, the environment surrounding it, and additional resources to help understand and interpret the findings. Students can record their observations in the Science Notebook, including the environmental factors and their tally of how many pieces of plastic they can identify during those 10 minutes.
- Where is the trash coming from? What does the kind of trash indicate about where it may have originated from?
- How might the trash be impacting the ecosystem?
- Why would the amount of trash shown in the live cam be variable? What factors influence how much trash there is?
- Was it easy or difficult to identify items?
- Did you see any wildlife?
Tips and Suggestions
- Suggested learning format: Students work in small groups to monitor for ten minutes. Have each group pick a notetaker.
