Description

Make life cycles and survivorship curves more meaningfulhands on, and inquiry driven with this fun case study on mangrove trees!

 

This lesson, although intended as a part of an NGSS Storyline on mangrove forests, can be used as a standalone lesson on the following topics:

  • What are the stages of a mangrove tree’s life?
  • How likely is it that a mangrove tree lives to each stage of life?
  • How does a mangrove tree reproduce in order to make up for low survivability of seedlings?

 

Lesson Overview:

In this lesson, the teacher may prefer to prepare the pieces of the mangrove life cycle ahead of time (printing, cutting, and laminating) or have students cut and glue in the classroom. There is also a digital version provided for virtual students or for anyone who prefers to reduce classroom materials.

 

First, students will be prompted to analyze text and images showing the mangrove life stages. Then, they will order the descriptions and photos to the best of their ability. Use the Google Slides presentation provided to check answers when everyone has completed the activity.

 

Then, the students will move into a data analysis portion of the lesson where they study survivorship curves and compare the different types. Students will draw conclusions about the adaptations that mangroves may develop in order to overcome their unique survival challenges. Specifically, that the majority of mangrove plants do not make it past the fruit or seedling change.

 

Who is this resource for?

This resource can be used by classroom teachers, tutors, and parents of students in grades 6-9. It comprehensively covers the topics mentioned, and provides opportunities for student responses which can be implemented in a whole group lesson or assigned for homework.

 

This lesson is a part of a NGSS storyline unit that addresses the question: What would happen if mangrove forests disappeared?

 

This resource was originally designed to be used to support the conservation and restoration efforts of the UAE’s rich mangrove forest ecosystems. It has since been modified for use around the world.

NGSS STANDARDS COVERED BY THIS MANGROVE LIFE CYCLES SURVIVORSHIP CURVES :

NGSSMS-LS1-4
Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively. Examples of behaviors that affect the probability of animal reproduction could include nest building to protect young from cold, herding of animals to protect young from predators, and vocalization of animals and colorful plumage to attract mates for breeding. Examples of animal behaviors that affect the probability of plant reproduction could include transferring pollen or seeds, and creating conditions for seed germination and growth. Examples of plant structures could include bright flowers attracting butterflies that transfer pollen, flower nectar and odors that attract insects that transfer pollen, and hard shells on nuts that squirrels bury.
