Teaching Tips | Science | Pedagogy |
- Most items found in typical classroom, but may need to order some supplies and brine shrimp in advance.
- Background information for teachers is included. Additional background information for students provided by the educator might be helpful.
- Instructions to students in both the lab activity and extended challenge might need additional clarification from educator, such as the purpose of lids for cups, diagram/photo of lab setups, labeling of containers, clear learning objectives, explanation of the term proxy and why brine shrimp are a good substitute for krill.
About the Science
- This is a lab activity in which students use brine shrimp as a substitute for krill to investigate how changes in environmental conditions (light, water temperature, water movement/currents, and magnetism) affect brine shrimp behavior.
- Gravity and magnetism are lumped together, perhaps implying that they are either synonymous or have the same effect on shrimp/krill behavior.
- Passed initial science review - expert science review pending.
About the Pedagogy
- Activity is a fun, hands-on investigation for students.
- Well thought-out lab with explicit LTER connection. Uses common supplies and provides range of suggestions for alternative methods of delivery. Some background information, activity sheets, and follow-on inquiries provided; educator must provide assessments.
