Description
“
Students learn how the nearest star to earth, Proxima Centauri, causes wavelengths of light to shift from red to blue giving evidence there is a “Super-Earth” orbiting it through a C.E.R. (Claim Evidence Reasoning) graphic organizer. This is great for getting your students to explain phenomena in a meaningful way and it allows you as the instructor to adequately assess their understanding of concepts. The students figure out what the “Claim” is in the article, they then use data that supports the claim in the “Evidence” section, draw visual evidence and then explain why the evidence supports the claim in the “Reasoning” section.
The article has the following concepts:
Proxima Centauri
Red Dwarf Star
The Sun
Galaxy
Binary Stars
Light-years
Red and Blue Spectrum of Light
Ultraviolet and X-rays
Light Frequency
Light Wavelength
Gravity
Uranus, Mercury and Neptune
Take a look at my CER Mega bundle!
This is great for a current event, sub plan, homework, critical thinking, scaffolding and/or reinforcement of concepts!
You get a CER graphic organizer, an editable key, the article, tips for CER and the link to the website in the article.
NGSS Standards:
DCI’s:
ESS1.A: The Universe and Its Stars
Earth and its solar system are part of the Milky Way galaxy, which is one of many galaxies in the universe. (MS-ESS1-2)
PS4.B: Electromagnetic Radiation
Electromagnetic radiation (e.g., radio, microwaves, light) can be modeled as a wave of changing electric and magnetic fields or as particles called photons. The wave model is useful for explaining many features of electromagnetic radiation, and the particle model explains other features. (HS-PS4-3)
SEP’s
Asking Questions and Defining Problem:
Students at any grade level should be able to ask questions of each other about the texts they read, the features of the phenomena they observe, and the conclusions they draw from their models or scientific investigations.
Engaging in Argument from Evidence:
In 9–12 builds on K–8 experiences and progresses to using appropriate and sufficient evidence and scientific reasoning to defend and critique claims and explanations about the natural and designed world(s). Arguments may also come from current scientific or historical episodes in science.
CCC’s
CCC1: Patterns
Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them.
