Nekton, a term that describes aquatic animals that are able to swim against the current, or move on their own accord, is an incredibly fascinating subject to teach to students of all ages. Whether it’s about whales and sharks or smaller creatures like octopus and squid, nekton creatures inhabit a world that is both alien and awe-inspiring to many students.
However, teaching students about nekton can be challenging, especially when it involves concepts like buoyancy, drag, and streamlining. Here are some tips and strategies to help you teach students about nekton:
Start with the basics
Begin by introducing the concept of nekton, explaining its definition, and its place within the ocean ecosystem. It’s essential to understand the difference between nekton and plankton, which are aquatic organisms that cannot move on their own and rely on currents to move them around. Basic concepts like these can help students prepare to learn more complex topics.
Use visual aids and models
Utilize resources such as videos, illustrations, diagrams, and models to demonstrate the various forms of nekton and how they differ from one another. For instance, show students how sharks and rays have unique streamlined shapes that allow them to glide through water with minimal drag or resistance. Have students to examine a whale’s baleen plates, which are used to filter tiny organisms out of the water that they eat.
Get hands-on
If possible, provide students with the opportunity to handle or observe different types of nekton in person, whether in an aquarium or through specimens brought into the classroom. This might include things like an octopus or squid. Consider partnering with local aquariums or marine conservation organizations who might be able to provide you with educational resources or even visiting your school as guest speakers.
Make it relevant
Encourage students to explore how nekton fits into the bigger picture of ocean conservation and how human activity can help or hurt nekton populations. Help students connect what they are learning with real-life situations, such as how overfishing can impact the population of certain species of nekton, or how pollutants like plastic can end up harming marine life.
Overall, teaching students about nekton involving a more hands-on and visual approach can make it an exciting and interesting topic for them. By providing them with a solid understanding of the basics and making it relevant, teachers can help students appreciate the wonder and importance of these remarkable creatures.
