5-PS2-1 Support an argument that diffences in the apparent brightness of the sun and stars is due to their relative distances from the Earth.
Practices: Planning and carrying out an investigaton, analyzing and interpreting data, engaging in an argument from evidence, obtaining, evaluating, and communicating information.
Core Idea: The sun is a star that appears larger and brighter than other stars because it is closer. Stars range greatly in their distance from Earth.
Crosscutting Concept: Patterns, Cause and Effect, Scale, Proportion, and Quantity
Your Task:
- Find the constellation Orion by using the star chart provided. You will find him in the southern sky.
- Locate Orion's shoulders and knee caps. (Betelgeuse, Bellatrix, Saiph, and Rigel). Use the star map to help you.
- Draw a model of the Orion constellation. Label Betelgeuse, Bellatrix, Saiph, and Rigel. Include the three stars the make up Orion's belt.
- Number each of the four labeled stars according to their brightness (1 being the brightest and 4 being the dimmest) .
- Research the number of light years each star is from Earth and include this information on your drawing. Take a second look at the Orion constellation and adjust your drawing if your interpretation has changed.
- The star "Sirius" is closer to Earth than all the stars in the Orion constellation. FInd it in the night sky and add it to your drawing to that I can use the Orion constellation to locate it in the night sky.
- Finally, answer this question in a complete sentence at the bottom of your drawing.
