Transferable/Scientific Skills Developed
Students will develop observing skills, measuring skills, analytical skills, critical thinking skills, problem-solving skills.

Students are introduced to different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction grating acts like a prism, bending light into its component colors.

General aim is to develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
Subject specific aim:
• Explain that light from different sources, when passed through a prism or diffraction grating, can be separated into component colors.
• Explain the basic tools engineers use to view spectra.
• Match a "barcode" spectrum with its corresponding line plot.

Linguistic aims:
- to listen English with ease
-to read English with ease
- to understand content
- to learn from written texts
- to express opinion
- to enable students to understand topic correctly

This task is aimed at students of 12-15 years old.
Level of competence in English (CEFR): A2 +/B1
Time required to use the resource with the students: 45 minutes

How to usit it:
This activity provides students with Graphing the Rainbow Activity - Worksheet.

Teacher use the sequence of activity, given in this resource:
• Summary
• Engineering Connection
• Learning Objectives
• Materials List
• Worksheets and Attachments
• Pre-Req Knowledge
• Introduction/Motivation
• Procedure
• Vocabulary/Definitions
• Assessment
• Troubleshooting Tips
• Activity Extensions

Possible difficulties for the students: students who have poor knowledge of English may have difficulties to understand the content.
Students should be familiar with line graphing methods and understand that graphs can be used to represent physical data. Students should have some understanding of the nature of light, i.e., rainbows are formed with light, light can be different colors, etc.

Strengths: students not only learn more topic related words but also expand their knowledge on the surrounding environment. Scientific reliability: The source is scientifically reliable as correspond to Educational Standards • NGSS: Next Generation Science Standards - Science • Common Core State Standards - Math • International Technology and Engineering Educators Association - Technology • State Standards Pedagogical values: peer-assisted learning, collaborative learning, language development across the curriculum, interdisciplinary, teaching complex thinking, teaching through conversation, contextualization.
