Building Safe Crossings for Animals

Difficulty: Grade 3-5
Time: 45-60 min
Categories:

In this lesson, students will explore the concept of wildlife crossings and their importance in preserving animal migration routes and protecting biodiversity. They will learn about different types of wildlife crossings, particularly focusing on animal land bridges and culverts.

Learning Goals

  • Explain how the human development of housing and roadways presents barriers for animals
  • Identify the different types of wildlife crossings
  • Explain how wildlife crossings help preserve biodiversity and ensure safe migration paths
  • Build a wildlife crossing prototype that:
    • uses a servo motor, solar sensor, and sonar sensor from the Climate Action Kit
    • automatically opens and closes the tunnel gate based on light levels
    • uses the sonar sensor to count animals as they cross

Materials

  • Climate Action Kit
  • micro:bit V2
  • Computer with access to Microsoft MakeCode
  • Optional: Flashlight

Get to Know the Content

  1. Make sure you've completed our 'Getting Started with the Climate Action Kit' course
  2. If it has been awhile, review the kit components featured in this lesson:
  3. Review the lesson, particularly the following thinking routines from Project Zero (Harvard Graduate School of Education):

Big Idea (30 minutes)

Learn about the importance of wildlife crossings and the challenges animals face in moving across human-made barriers.

Students will:

  • Explore the reasons animals need safe crossings, especially on busy roads.
  • Discuss how wildlife crossings, such as bridges and tunnels, help animals move safely.
  • Describe three ways scientists study wildlife crossings to determine their effectiveness

Take Action (60 minutes)

Students will build their own wildlife crossing prototype that is capable of automatically opening and closing gates and counting the number of animals that cross.

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 wildlife crossing prototype.

Success Criteria

I can:

  • build a wildlife crossing with a bridge and a tunnel
  • predict how different animals, like deer or turtles, might use the crossing
  • explain how to use button press events and a motor to open and close the tunnel gate
  • explain how to use variables to count the number of animals that cross the bridge or tunnel

Resources

Tutorial
Final Code
Modify

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

Success Criteria

I can:

  • build a wildlife crossing with a bridge and tunnel
  • explain how sensors and conditional statements can be used to automate tasks
  • write a conditional statement that uses the solar sensor to open the gate during the day
  • write a conditional statement that uses the sonar sensor to count animals as they pass

Resources

Tutorial
Final Code
Create

Students will work in a small group to design, build & code their own wildlife crossing prototype.

Success Criteria

I can build a wildlife crossing prototype with the Climate Action Kit that:

  • has both a bridge and a tunnel for animals of different sizes
  • automatically counts the animals that cross
  • prevents predators from trapping prey in the tunnel

and uses at least:

  • one sensor

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

Conversations

  • Explain how wildlife crossings help animals cross safely
  • List two benefits of using sensors and coding to automate wildlife crossings (Use, Modify, Create)
  • Discuss the role of each smart component (servo motor, solar sensor, sonar sensor) in the main build (Use, Modify, Create)
  • Explain how conditional statements are used to automate the gate and count animals (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 their own conditional statements for automating the crossing (Modify, Create)
  • Design their own prototype that satisfies provided criteria (Create)
