Lesson Plan Template: Backward Design Approach

Experiential learning method for a 5th-grade science class

Objective: 

Students will understand the concept of light reflection and its properties through hands-on activities and group discussions.

Materials Needed:

1. Small mirrors (one for each student or group)
2. Flashlights (one for each student or group)
3. Whiteboards or large chart paper
4. Markers
5. Paper
6. Pencils

Lesson Plan:

1. Introduction (5 minutes):

1. Begin the lesson by asking students if they know what happens when light hits a mirror.
2. Engage students in a brief discussion about their observations and prior knowledge regarding light reflection.
3. Introduce the concept of light reflection by explaining that when light hits a smooth surface, it bounces back and changes direction.

2. Hands-on Activity: Mirror Reflection (15 minutes):

1. Distribute small mirrors and flashlights to each student or group.
2. Instruct students to turn off the classroom lights and shine the flashlight onto the mirror.
3. Encourage students to observe the direction in which the light reflects off the mirror.
4.  Ask students to record their observations in their notebooks or on a worksheet.

3. Group Discussion (10 minutes):

1. Have students gather in small groups to discuss their observations and share their ideas about light reflection.
2. Ask each group to select a spokesperson to present their findings to the class.
3. Lead a class discussion based on the group presentations, focusing on the key properties of light reflection.

4. Demonstration: Angle of Incidence and Reflection (5 minutes):

1. Use a whiteboard or large chart paper to draw a diagram illustrating the angle of incidence and the angle of reflection.

1. Explain that the angle of incidence is the angle at which light hits a surface, and the angle of reflection is the angle at which it bounces off.

1. Use the diagram to demonstrate how the angles of incidence and reflection are measured and related to each other.

5. Application Activity: Light Reflection Scavenger Hunt (5 minutes):

1. Divide the class into small groups and distribute paper and pencils to each group.
2. Instruct students to go around the classroom or school, identifying examples of light reflection.
3. Each group should record their findings and draw diagrams or write explanations of how light reflects in each scenario.

6. Conclusion (5 minutes):

1. Bring the class back together and have each group share their scavenger hunt findings.
2. Summarize the main points discussed during the lesson, emphasizing the properties of light reflection.
3.  Address any remaining questions or concerns from the students.

Extensions/Assessments (if time allows):

Students can research and create a poster or presentation on real-world applications of light reflection, such as mirrors, periscopes, or solar panels.

Assess student understanding through a short quiz or a reflective journal entry, where they write about their experience and understanding of light reflection.

Note: 

The duration of each activity can be adjusted based on the pace and engagement of the students. It is essential to be flexible and provide support and guidance throughout the lesson as needed.
