This activity explores an image of a mosquito’s mouthparts, which serves as a phenomenon for learning about vectors of disease.
Mosquitos are effective vectors that transmit disease-causing pathogens. Mosquitoes are the main vectors, for example, for the pathogens that cause dengue, chikungunya, West Nile fever, and Zika. Biologists and medical experts work to control the spread of vector-borne diseases by studying the life cycle, physiology, and behavior of vectors and the pathogens they carry. By understanding vectors and their pathogens, we can better understand how diseases spread and how to develop effective management and control strategies to reduce disease transmission.
The “Educator Materials” document includes background information and implementation suggestions for using the image as a phenomenon. The “Student Handout” includes the image and background information.
Student Learning Targets
- Examine images of phenomena, make observations, and ask questions.
- Collaborate with peers on ideas, ask questions that require higher levels of reasoning, and develop deeper understanding of concepts.
- Apply knowledge about the biology of mosquitoes to construct hypotheses, experiments, and disease management strategies.
