Patterns in the Night Sky: Stars and Constellations

Learning Objectives

• Explain that the Sun is a star and why it appears larger and brighter than other stars.
• Describe how stars differ in color, size, temperature and apparent brightness.
• Explain what constellations are and why their positions change during the night and through the year.

How to Use This Resource

• Start with slide 1: ask, "Is the Sun a star? Why does it look so different from the stars at night?"
• Teach star properties, distance and brightness, constellations and apparent motion with the slides, then do activities 1 and 2 together.
• Students complete activities 3 to 6, then use the quiz to check and the homework stargazing task. Answers are in the answer key.

Classroom Activity Ideas

• Flashlight distance: two students hold the same flashlight at different distances; the class compares how bright each looks.
• Make a constellation viewer: punch holes in a paper cup base in the pattern of Orion and shine a flashlight through it onto the ceiling.
• Spinning classroom: students turn slowly on the spot while looking at star pictures on the walls to see why stars seem to move.

Differentiation

Support: give a labeled star color chart and a picture of Orion, and focus on the Sun as a star and constellations. Challenge: research the life cycle of a star and explain why the North Star seems to stay still while other stars move.

Assessment

Worksheet activities and the quiz check star properties, brightness, constellations and apparent motion (answer key included). Explanations and the homework observation are checked with the rubric.

Teacher Tips

Many students think stars disappear in the daytime. Explain that the stars are still there, but sunlight is so bright that we cannot see them, just as a flashlight is hard to see outside at noon.
