  • Changes in the environment affect some organisms' ability to survive and reproduce, cause others to move to new locations, yet others to move into the transformed environment, and cause some to die.
  • Populations live in a variety of habitats, and change in those habitats affect the plants and animals living there.

Skills

Students are able to:
  • Identify problem created by environmental changes.
  • Make a claim about an engineered solution to a problem created by environmental changes.
  • Identify the effects of solutions to a problem created by environmental changes that impact the plants and animals living in the environment.
  • Communicate evidence to support the claim about an engineered solution to a problem created by environmental changes.

Understanding

Students understand that:
  • That plants and animals within an environment make up a system, and changes to one part of the system impacts other parts.
  • Engineers design solutions to problems created by environmental changes that sometimes impact the plant and animal populations found there.

Procedures/Activities

Before: (Days 1-3)

The teacher will guide a class discussion regarding the students' experience with the environmental elements at the beach such as seaweed, sea shells, and coral. The teacher can also ask probing questions, such as "Have you ever snorkeled and viewed a fish swimming in the ocean?"

The teacher will introduce the lesson by playing the video from The Nature Conservancy:

The Nature Conservancy's underwater coral nursery project

The teacher will define the vocabulary words for students to copy onto flash cards (index cards). The teacher will create an anchor chart of the terms and definitions for students:

  1. nursery-any place in which something is bred, nourished, or fostered

  2. coral reef-a reef composed mainly of coral

  3. reef-a ridge of rocks or sand, often of coral debris, at or near the surface of the water

  4. habitat-the natural environment of an organism; place that is natural for the life and growth of an organism

  5. environment-the air, water, minerals, organisms, and all other external factors surrounding and affecting a given organism at any time

  6. resources-a source of supply, support, or aid, especially one that can be readily drawn upon when needed

  7. propagation-multiplication by natural reproduction

  8. restoration-the act of restoring; renewal, revival, or reestablishment

  9. climate change-a long-term change in the earth's climate

The students will make flashcards to study the nine terms listed above to be incorporated into their discussions and reflections as it applies to the evaluation of the Coral Reef Nursery.

  • The teacher will explain to the students that many variables influence the underwater environment.

  • The teacher will explain to the students that they will soon begin to evaluate a solution to a problem that has occurred recently with something under the ocean that is responsible for the health of the entire ocean.

  • The teacher will introduce the lesson by displaying the article from the Nature Conservancy: Restoration Works Coral Reef Restoration.

  • The teacher will distribute three sticky notes to each student.

  • The students will listen as the teacher reads the article out loud (the text could be a challenging read for most third graders).

  • The teacher will stop at the end of each paragraph and allow students to write their thinking down on sticky notes.  At the end of each of the three sections, students will write a question or an important detail that they took away from the article.

  • The teacher will allow students to keep their sticky notes for discussion in their assigned groups.

  • The teacher will underline the quote from the article stating the environmental problem is: “Staghorn and Elkhorn coral populations in the Florida Keys, the Dry Tortugas, and the U.S. Virgin Islands have declined by more than 97  percent.” The teacher will document this problem on an anchor chart.

  • The teacher will use The Continents and Oceans Map to locate and mark the area where the coral reef nursery is currently located.

  • The teacher will underline the quote from the article stating the engineered solution to the problem, “The Nature Conservancy and its partners are cultivating underwater nurseries to revive degraded coral reefs.” The teacher will document this engineered solution on the same anchor chart.

  • The teacher will ask the probing question, “Can reseeding reefs and building new nurseries help corals face new threats like the Gulf oil spill and climate change?” The teacher will document this question on the same anchor chart and document student responses to the question.

  • The teacher will ask students, “If the coral nursery fields are thriving at a given rate, how effective or ineffective is the engineered solution?” The teacher will document this question on the same anchor chart and document student responses to the question.

  • The teacher will ask students, ”Because these fields are thriving from Miami, Florida to the Virgin Islands, what do we know about other climates, habitats, or environments that could increase the effectiveness of this solution?" The teacher will document this question on the same anchor chart and document student responses to the question.

  • The teacher will play the video interviewing those on the coral reef nursery process, Florida The Coral Nursery.

  • The teacher will then have students refer to their sticky notes from the first passage.

  • The students will turn and talk to their elbow partner (students sitting immediately to their left or right) and attempt to answer the questions they had with their peer or share the facts they found important from the article.  

  • The teacher will listen in on student elbow partner (student to the left or right of the student) conversations and will be sure to acknowledge on task thinking, unique ideas, and incorporation of vocabulary taught.

The teacher will write the three essential questions to the evaluation of the engineered solution on chart paper for students to refer to throughout the process:

  1. How would you aid in the cause?

  2. Could manipulating the location of the fields help increase the effectiveness of this solution?

  3. How could you design a better solution to increase effectiveness?

  • The teacher will tell the students that they will now use their knowledge gained from the reading and videos to discuss ways to expand the size of coral reef nursery, which is already in place.

  • The students will also use their knowledge gained from the reading and videos to discuss ways to increase the effectiveness of coral reef nursery, which is already in place.

  • The students will take “silent wait time” (10-30 seconds) to think about what may be a better approach to the coral reef nursery.

  • Next, the students will write their idea on a sticky note.

  • The students will then turn and talk to their elbow partners about what they wrote on their sticky note.

  • The teacher will listen in on student elbow partner (student to the left or right of the student) conversations and will be sure to acknowledge on task thinking, unique ideas, and incorporation of vocabulary taught.

  • The teacher will prompt students in peer discussions if any student appears to be off task or has trouble conveying ideas.

  • Finally, the teacher will choose a couple of sticky notes per table and write the students' ideas on chart paper.

During: (Days 4-7)

  • The teacher will introduce the link Reef Resilience Toolkit for students to evaluate the tools that can be used to help answer the essential questions.

  • Students will use internet access with Chromebooks or portable devices (such as tablets) to begin researching their ideas on how they will make a better attempt at the currently effective and utilized coral reef nursery.

  • The teacher will provide links to each student group. Students will use the following links to gain knowledge on the best ways to help coral grow Reef Resilience Toolkit, How To Grow Coral 101: The Basics, CORAL keeping How to make them thrive, Coral Food: Make Your Corals Fat and Healthy, A Breakthrough for Coral Reef Restoration

  • The teacher will facilitate the research process as needed and ensure all students are on task while using internet access appropriately.

  • Students will collaborate with their groups to draw a design of a better attempt at the currently effective and utilized coral reef nursery.

  • The students will use the group design (drawing) to guide the hypothetical construction process.

  • The students will use The Continents and Oceans Map (one printed out for each group) to locate and mark the area that their group would plant the new coral nursery.

  • The students will document in their journals the elements that influenced them in placing the new coral reef nursery in the chosen location.

The teacher will ensure each group is answering the essential questions:

  1. How would you aid in the cause?

  2. Could manipulating the location of the fields help increase the effectiveness of this solution?

  3. How could you design a better solution to increase effectiveness?

After: (Days 8-10)

The teacher will display, review, and provide each group a copy of the rubric (Coral Reef Nursery Evaluation Presentation) before students begin to create their presentation.

Each group will create and present an Animoto presentation consisting of at least 5 slides:

  • Three slides will be used to address each of the three essential questions.
  • One slide will have a map image for where the group would locate a new coral reef nursery. The map image will be captured by taking a picture of the map with the tablet or portable device.
  • One slide will have the drawing of the design of a better attempt at the currently effective and utilized coral reef nursery. The drawing of the design will be captured by taking a picture of the drawing with the tablet or portable device. 

Assessment Strategies

  • The teacher will informally assess students’ claim and plan by observing student conversations during group work while ensuring students document their theories and plan of action they discuss in their journals.

  • The teacher will informally assess students’ ability to transfer knowledge of habitat, environment, and climate properly to where the new coral reef will be located by asking probing questions such as:

    “What about the climate is aiding in the effectiveness of the coral reef nursery?”

    “What other environments will be as effective?”

  • The teacher will informally assess the students’ evidence that does or does not support their claim by listening for vocabulary words taught explicitly (nursery, coral reef, habitat, environment, resources, propagation, restoration, climate change). Students should accurately communicate the connection to the content, while the teacher ensures students document the theories they discuss in their journals.

  • The teacher will informally assess students as the groups use the three essential questions to guide their research while ensuring students document the theories they discuss in their journals.

  • The teacher will formally assess the students’ learning objectives by using a rubric to guide and score the group’s Animoto presentation (Coral Reef Nursery Evaluation Presentation).

Acceleration

Students working at an accelerated level who have completed the essential questions may choose to use The Nature Conservancy Website link (Oceans and Coasts Restoration Works) to choose another engineered solution and complete the same essential questions.

  • Students will be responsible for maintaining a journal that documents the completion of the essential questions.

Intervention

  • The teacher will allow peer tutors for completion of vocabulary index cards as they will pertain to discussion and reflection of extending and enhancing the engineered solution.
  • The teacher will prompt students in peer discussions if any students appear to be off task or are having trouble conveying ideas.
  • The teacher may need to facilitate certain groups if there appears to be a lack of cohesiveness to the task in order to facilitate productive collaboration.
