Material / Resources
A chart of large comport similar URSA major vi pieces of chalks of dark & bluish color, 10 gummed stars, white crayon, bluish or dark figurer sheet, pencil & pages
Worm upwardly activeness
· Paste the gummed star on the dark paper.

· Now say the students that these patterns of stars are called the constellations.
Development
Activity 1
· Make the next tabular array on the board.
Sr. no. | Bodies inward space | Emitting light | Reflecting lite |
1 | Sun | ||
2 | Moon | ||
3 | Earth | ||
4 | Comet | ||
5 | Asteroid | ||
6 | Meteor |
· Ask the students to re-create in addition to fill upwardly the table.
Sr. no. | Bodies inward space | ||
1 | Sun | Emitting light | |
2 | Moon | Reflecting light | |
3 | Earth | Reflecting light | |
4 | Comet | Emitting light | |
5 | Asteroid | Reflecting light | |
6 | Meteor | Emitting light |
Activity 2
· Ask the student’s conditions they accept seen an X ray, for certain to a greater extent than of the students volition response is yes.
· Ask 1 of the students to convey an one-time X ray canvass in addition to a cello record tomorrow.
· On the side past times side twenty-four lx minutes menstruum aid the students inward mapping a security viewer to thought the Sun as:
v Cut 2 circles of close cm diameter from the sheet.
v Round a cardboard to brand a cylinder of the same diameter alongside the aid of cello tape.
v Paste both the X ray round down canvass placed 1 inward a higher house the other at 1 halt of the cardboard cylinder in addition to create it alongside the cello tape.
v Now thought the Sun through this security viewer. You tin mail away detect the Sun easily.
v Call some students 1 past times 1 to thought the Sun through it.
v All the students volition engage the activity.
v At the halt say the students that it is rattling unsafe to thought the Sun straight alongside naked eyes.
v Now say them another security methods to thought the Sun safely.
Sum upwardly / Conclusion
· There is large publish of constellations inward the sky.
