Space Exploration – Telescopes
Learning Objectives
- Describe the evolution and significance of telescopes in space exploration.
- Explain the differences between optical, radio, and space telescopes.
- Identify the advantages and limitations of ground-based and space-based telescopes.
- Discuss the contributions of the Hubble and James Webb Space Telescopes to our understanding of the universe.
Introduction and Hook
Engage students with a brief overview video on space exploration technologies, including telescopes, to spark interest and curiosity.
Direct Instruction
Explain the differences between optical, radio, and space telescopes, emphasizing their unique features and contributions to space exploration.
Discuss the advantages and limitations of ground-based versus space-based telescopes, using examples like the Gran Telescopio Canarias and ALMA.
Guided Exploration
Explore the contributions of the Hubble and James Webb Space Telescopes through a video that highlights their discoveries and technological advancements.
Facilitate a discussion on how these telescopes have expanded our understanding of the universe, encouraging students to share their thoughts and questions.
Hands-On Activity
Conduct a classroom activity where students create simple models of telescopes using lenses and mirrors to understand how they magnify distant objects.
Use the 'Modeling the Earth’s Rotation' assessment to help students simulate and understand the effects of Earth's rotation on observations from telescopes.
Independent Practice
Assign students to research a specific telescope (optical, radio, or space) and present their findings on its significance and discoveries.
Check for Understanding
Use the 'Earth’s Orbit and Seasons – Comprehension' assessment to evaluate students' understanding of how Earth's movements affect observations from telescopes.
Review and Reflection
Encourage students to reflect on what they have learned about telescopes and their impact on space exploration. Discuss any new questions or interests that have arisen.
Assessment and Extension
Conclude with a quiz to assess students' comprehension of the lesson's key concepts, including the types and roles of telescopes in space exploration.
