Symbiosis

In today’s lesson the class differentiated between the three types of symbiosis: mutualism, commensalism, and parasitism. We explored examples of these types of relationships through a game where each student was given an organism card with hints. The students went around the room and had to find their “symbiotic partner” and identify which of the three types of relationships their organisms shared. Finally, using their creativity skills, they depicted the different symbiotic relationships on paper.

Symbiosis

Standard: (HCPS III) SC.4.3.2 – Student describes how an organism’s behavior is affected by its environment. SC.MS.5.3 – Student classifies symbiotic relationships in the marine environment.

TSWBAT: Identify the different types of symbiosis by playing a card game that will help them match marine animals with their symbiotic partners.

Materials:

  • exploration of the three types of symbiosis
  • symbiosis card game
  • videos of symbiotic relationships

Vertebrates

Today the small group of Jefferson Marine Club students expanded on last weeks lesson and talked about vertebrates. We used dichotomous keys for cetacean species and shark species, students got to test what they learned last week about the keys to label different species in these categories. We also had sample specimens that the students classified as vertebrate or invertebrate and then used for a Gyotaku activity. Some students were excited to feel the creatures while others took a little longer to warm up to the idea of touching them!

Vertebrates

Standard: (HCPS III) SC.MS.5.2 - The student classifies planktonic, invertebrate, and vertebrate organisms based on their characteristics. SC.Z.3.3 - The student classifies organisms as vertebrates or invertebrates.

TSWBAT: Demonstrate their understanding of marine vertebrates using dichotomous keys to figure out some marine vertebrate species.

Materials:

  • dichotomous keys for some vertebrate species
  • samples of dead or live marine vertebrates
  • paint/brushes/paper

Invertebrates

This Friday, Jefferson students learned what a dichotomous key was by comparing it to the handheld 20Q game. Each student then practiced using a simple invertebrate dichotomous key to classify some organisms into the correct phylum: porifera, cnidaria, echinodermata, arthropoda, and mollusca. We then used our classifications to identify some of the defining characteristics of each phylum. These included nematocysts, radial symmetry, segmented bodies, soft bodies and hard shells. In addition to these differences, we concluded that one thing all these organisms had in common was the lack of a backbone

Invertebrates

Standard: (HCPS III) SC.MS.5.2 - The student classifies planktonic, invertebrate, and vertebrate organisms based on their characteristics. SC.Z.3.3 - The student classifies organisms as vertebrates or invertebrates.

TSWBAT: Define a marine invertebrate and use a dichotomous key to categorize some marine invertebrates based on physical characteristics.

Materials:

  • invertebrate dichotomous key
  • examples of marine invertebrates
  • invertebrate activity

Endangered Species

Jefferson Marine Club had so much fun learning acronyms last week that we added a few more this week. Building on our last lesson to cover endangered species in Hawaii, we briefly talked about the Marine Mammal Protection Act (MMPA) and Endangered Species Act (ESA) and then focused in on Hawaiian Islands Humpback Whale National Marine Sanctuary (HIHWNMS), whew! Considering we are right in the middle of “whale season” here in Hawaii, we talked about the Sanctuary Ocean Count that monitors Humpback population and distribution around Oahu, Hawaii, and Kauai. We discussed a few of the behaviors that the Ocean Count observes: Blow, Breach, Pectoral Slap, Tail Slap, and Dive. The students then spent the rest of our time designing their own protected species puzzles!
