ASSESSMENT & EVALUATION

Formative

• Observations during group discussions and poster activities will informally assess student understanding.

Summative

• Multiple Choice Questions:
  1. What is a black hole?
     • a) A large star
     • b) A region in space with a gravitational pull so strong that nothing can escape
     • c) A type of planet
     • d) A comet
  2. How is a black hole formed?
     • a) Through the explosion of a star
     • b) By merging of two planets
     • c) By cooling of gas
     • d) By dark matter
  3. What is the event horizon?
     • a) The surface of a star
     • b) The boundary around a black hole beyond which nothing can return
     • c) A type of galaxy
     • d) A space station
• Short Answer Questions:
  1. Describe one characteristic of a black hole.
  2. What role does gravity play in the formation of a black hole?
  3. Why are black holes significant to our understanding of the universe?

Rubric for Performance Tasks:

• Excellent (4 points): Comprehensive understanding and accurate representation of black hole concepts.
• Good (3 points): Clear understanding with minor errors.
• Fair (2 points): Basic understanding but lacks detail.
• Needs Improvement (1 point): Limited or incorrect understanding.

CONTENT & SUBJECT MATTER

Topic

• Black Holes

Reference

• DepEd Science Curriculum Guide, Grade 8, pp. 45-50

Materials

• Whiteboard and markers, projector, science textbooks, printed images of black holes, and drawing paper.

Values Integration

• Promoting curiosity and respect for the universe and its mysteries, fostering critical thinking about scientific phenomena.

LEARNING ACTIVITIES (5E Model)

Engage

• Begin with a video clip showing a simulation of a black hole and its effects on surrounding stars. Ask students what they think is happening and their thoughts on black holes.

Explore

• Provide students with printed images and diagrams of black holes. In small groups, let them discuss and identify characteristics and features they observe.

Explain

• Present a brief lecture on the formation of black holes, types of black holes, and their significance in the universe, using a PowerPoint presentation.

Elaborate

• Invite students to create a poster illustrating the life cycle of a star leading to a black hole. Discuss how gravity plays a role and relate it to real-life examples such as gravitational pull on Earth.

Evaluate

• Conclude with a quick quiz consisting of 3 multiple-choice questions about key concepts covered. Ask students to share one new thing they learned about black holes.

ASSIGNMENT & REMARKS

• Homework: Write a short essay (150-200 words) on how the study of black holes can impact our understanding of the universe.
• Extension Activity: Research a recent discovery related to black holes and prepare a short presentation for the class.
• Real-world Connection: Discuss how black holes can be related to the concept of gravity affecting our daily lives, such as satellite movements and space travel.
• Remarks: Ensure students reflect on their learnings and share their thoughts during the next class.

LEARNING OBJECTIVES

• At the end of the lesson, students will be able to describe what a black hole is and its characteristics.
• Students will be able to illustrate the formation of black holes using diagrams.
• Students will demonstrate curiosity and engagement by asking relevant questions about black holes.
• Students will evaluate the impact of black holes on the universe through discussion.
