Beach Lighting for Sea Turtle Conservation

  • Difficulty: Grade 6-8
  • Time: 45-60 mins
  • Categories: Oceans

In this lesson, students will learn about the important roles sea turtles play in maintaining marine ecosystems. They'll explore how light pollution threatens sea turtle populations and how simple design changes can have a major impact on life under water.

Overview Accordion

Learning Goals

  • Explain at least two roles sea turtles play in marine ecosystems
  • Describe the impact artificial lighting has on sea turtle behaviour
  • Discuss the importance of preserving sea turtles
  • Build a sea turtle-friendly beach light that uses:
    • the solar sensor, sonar sensor and LED ring from the Climate Action Kit, and
    • standard, compound, and nested conditional statements to adjust the brightness of the beach light based on different environmental signals

Activity Accordion

Big Idea (15 minutes)

Learn about sea turtle behaviour and the important roles these species play in maintaining ocean ecosystems.

Students will:

  • identify the many roles sea turtles play in ocean ecosystems
  • compare and contrast two sea turtle nesting beach scenes
  • learn how light pollution threatens sea turtle survival

Take Action (45 minutes)

Students will explore how we can minimize shoreline light pollution with technology. They will build their own sea turtle-safe beach light with the Climate Action Kit.

We've provided 3 ways students may build the project to support scaffolding and differentiation in your classroom: 'Use', 'Modify', and 'Create'.*

Activity Description
Use

Students will follow a step-by-step tutorial to build & use their beach light.

Success Criteria

I can:

  • build a sea turtle-safe beach light with the Climate Action Kit
  • explain the effect environmental light levels have on the beach light
  • identify conditional statements within code
  • make suggestions to make my light even more turtle-safe

Resources

Tutorial
Final Code
Modify

Students will follow a step-by-step tutorial to build their beach light. After this, they will modify the code and complete a challenge to demonstrate their understanding.

Success Criteria

I can:

  • build a sea turtle-safe beach light with the Climate Action Kit
  • make changes to my code to learn how it works
  • use operators to write Boolean expressions
  • create compound and nested conditionals to adjust the brightness of my beach light based on different environmental conditions

Resources

Tutorial
Final Code
Create

Students will work in a small group to design, build & code their own sea turtle-safe light.

Success Criteria

I can build a sea turtle-safe light that is physically:

  • low to the ground
  • dim
  • red or amber in colour
  • shielded

and uses:

  • two sensors to respond to the environment
  • one compound conditional statement

Assessment Accordion

Use the following criteria to assess student learning. Students can:

Conversations

  • Describe the impact artificial lighting has on sea turtle behaviour
  • Construct an argument to justify the importance of saving sea turtles
  • Explain the purpose of each smart component and building block in the main build (Use, Modify, Create)
  • Explain the purpose of the different types of conditional statements in the sea turtle-safe beach light project (Use, Modify, Create)

Observations

  • Methodically test and debug their code to ensure it functions as intended (Modify, Create)

Products

  • Add comments to the code to demonstrate their understanding of each block (Use, Modify, Create)
  • Create a standard, compound, and/or nested conditional statement that represents a decision making point within their algorithm (Modify, Create)
  • Design their own prototype that satisfies provided criteria (Create)
