Beginning

3 min

1.      The teacher introduces the lesson and states the objectives. The teacher may also check the homework from the previous lesson

10 мин

10 min

15 min

2.      The  teacher to lead in the discussion using a power point presentation on the following:

·         Newton’s law of gravitation

·         Acceleration due to gravity

·         Centripetal force and gravity

·         Gravitational field strength

3.      Gravitation Field Modeling

Students determine relationships between values.

4.      Students to attempt questions from the worksheets.

The teacher assist the learners with difficulty.

1. During a solar eclipse, the Moon, Earth, and Sun all lie on the same line, with the Moon between Earth and the Sun. The mass of the sun M_S = 1.991 x 10³⁰ Kg , mass of moon M_M = 7.36 x 10²² Kg. The distance between the sun and the moon is 1.496 x 10¹¹ m while the distance between the moon and the earth is 3.81 x 10¹⁰ m

(a) What force is exerted on the Moon by the Sun?

(b) What force is exerted on the Moon by Earth?

(c) What force is exerted on Earth by the Sun?

4. This question is about gravitational fields.

(a)Define gravitational field strength.

 (b)The gravitational field strength at the surface of Jupiter is 25 N kg–1 and the radius of Jupiter is 7.1 × 107 m.

(i)Derive an expression for the gravitational field strength at the surface of a planet in terms of its mass M, its radius R and the gravitational constant G.

(ii)Use your expression in (b)(i) above to estimate the mass of Jupiter.

End

2 min

At the end of the lesson, learners reflect on their learning:

-       What has been learned

-       What remained unclear

-       What is necessary to work on

Home work

Reflection

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check students’ learning?

Health and safety regulations

Most learners should be able to recall the main aspects of the specified areas

Some learners will not be able to attempt all the questions.

Learners group according to their ability. Learners who are able will be given extra work.

Use of AfL, Q/A and FA

Students to place their bags in designated areas to avoid minor accidents.

Reflection

Were the lesson objectives/learning objectives realistic? Did all learners achieve the LO?

If not, why?

Did my planned differentiation work well?

Did I stick to timings?

What changes did I make from my plan and why?

Use the space below to reflect on your lesson. Answer the most relevant questions from the box on the left about your lesson.
