Learning Goals
- List at least three different components of a coral reef ecosystem
- Identify the main parts of a coral polyp
- Describe the process of coral bleaching and its impact on marine life
- Explain why scientists use models to study and protect coral reefs
- Build a coral reef model that simulates coral bleaching as the water temperature rises
Materials
- Climate Action Kit
- micro:bit V2
- Computer with access to Microsoft MakeCode
- White tissue paper (Keep this free of foil or glitter so it can be recycled or composted later!)
Get to Know the Content
- Make sure you've completed our 'Getting Started with the Climate Action Kit' course
- If it has been awhile, review the kit components featured in this lesson:
- Review the lesson, particularly the following thinking routines from Project Zero (Harvard Graduate School of Education):
Big Idea (15 minutes)
Learn about coral reefs and how warmer oceans can harm them by causing coral bleaching.
Students will:
- Compare and contrast healthy vs. bleached coral reefs
- Explain how coral bleaching affects coral reef ecosystems
- List the ways scientists and communities are working together to protect coral reefs
Take Action (45 minutes)
In the Take Action section, students will use the Climate Action Kit to design and build their own coral reef model. The model will change colour to show how bleaching occurs when the water temperature rises.
We've provided 3 ways students may build the project to support scaffolding and differentiation in your classroom: 'Use', 'Modify', and 'Create'.*

Students will follow a step-by-step tutorial to build and use their coral reef model. Success CriteriaI can:
ResourcesTutorialFinal Code |
Modify |
Students will follow a step-by-step tutorial to build the coral reef model. They will improve upon the model by modifying the code and ensuring bleaching happens more gradually. Success CriteriaI can:
ResourcesTutorialFinal Code |
Create |
Students will work in a small group to design, build, and code their own coral reef model. Success CriteriaI can build a coral reef model with the Climate Action Kit that uses the LED ring to visually represent the coral's health at different temperatures. ResourcesBlank Project |

Use the following criteria to assess student learning. Students can:
Conversations
- Discuss how temperature changes can lead to coral bleaching
- Explain why coral is important for ocean animals
- Explain how the coral reef model works to show bleaching
- Describe how conditional statements in the code control the colour changes of the coral
Observations
- Methodically test and debug their code to ensure the tumbler spins and rests as intended (Modify, Create)
Products
- Add comments to the code to demonstrate their understanding of each block (Use, Modify, Create)
- Write new conditional statements to show coral bleaching happen gradually (Modify, Create)
- Design a coral reef model that meets the provided criteria (Create)

3-LS2-1 Construct an argument that some animals form groups that help members survive.
3-LS3-2 Use evidence to support the explanation that traits can be influenced by the environment.
3-LS4-3 Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.

Common Core State Standards for Mathematics
Grade 3-5
3.NF.A.1 Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
3.MD.B.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
4.NF.B.3 Understand a fraction a/b with a > 1 as a sum of fractions 1/b.
a. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
b. Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8
d. Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.
5.NF.A.2 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
