What is the Universe?
Learning Objectives
- Understand the hierarchical structure of the universe from local to cosmic scales, including the concepts of solar systems, galaxies, and the universe.
- Explain the concept of a galaxy and identify the Milky Way as the galaxy containing our solar system.
- Describe the Big Bang Theory as the scientific explanation for the origin and expansion of the universe.
- Recognize the universe as a vast expanse that includes everything that exists, from the smallest particles to the largest galaxies.
- Identify the expansion of the universe as evidence for the Big Bang Theory and the continuous movement of celestial objects.
Introduction and Hook
Engage students with an introductory video that illustrates the vastness of the universe and its components.
Direct Instruction
Explain the hierarchical structure of the universe, from solar systems to galaxies and the universe itself.
Introduce the concept of galaxies, focusing on the Milky Way as our home galaxy.
Guided Exploration
Watch a video on the Big Bang Theory to understand the origin and expansion of the universe.
Discuss the evidence supporting the Big Bang Theory, such as the expansion of the universe.
Hands-On Activity
Conduct a hands-on activity where students create a model of the universe's expansion using balloons to represent galaxies.
Independent Practice
Assign students to research different types of galaxies and present their findings.
Check for Understanding
Use the 'Galaxy Classification' assessment to evaluate students' understanding of different galaxy types.
Review and Reflection
Facilitate a class discussion reflecting on the key concepts learned about the universe and its components.
Assessment and Extension
Assign the 'The Big Bang' assessment to test students' comprehension of the universe's origins and expansion.
Encourage students to take the unit quiz to assess their overall understanding of the universe.
