Learning objectives that are achieved at this lesson

Determination of relative accuracy at measuring of physical quantities;

Lesson objectives

- Develop skills to work with the results of the experiment;

- Find from given equation the gradient and Y-intercept.

- Develop skills to draw graphics;

- Calculate gradient;

- Calculate uncertainties.

Success criteria

Students have achieved if they:

- Are able to analyse the results of the experiment;

- Find from given equation the gradient and Y-intercept.

- Correct draw graphics;

- Calculate gradient;

- Calculate uncertainties.

Language objectives

Uncertainties, gradient, Y-intercept, the best fit line, percent uncertainty, constant quantity, variable quantity, graph.

Values instilled at the lesson

Students’ achieve of specific learning objectives, and get a certain amount of knowledge, but also develop the ability to apply their knowledge in solving learning and life problems;

Cross-curricular links

Values links Mathematics by straight line equations;

First part.Practical work. Work with the class.

Students will investigate how the force required to pull a block up an inclined plane depends on the angle between the inclined plane and the bench.

Paper 1 or 2 of CIE: 9702/31/M/J/12 or9702_w09_qp_52.The teacher observes checks and evaluates the students. Gives feedback to the students.

Second part. Alternative to practical.

Paper 3 or 4 of CIE: 9702/53/O/N/13. Problem N 2.

Students work independently.

The teacher observes, checks and evaluates the students.

Gives feedback to the students.

Generalization: Students will be asked if they have achieved the lesson’s objectives.

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

Differentiate by questions at the starter;

Differentiate students for creating definitions;

Differentiate persons in groups;

Differentiate problems and questions at the end;

Questions by right or wrong answers;

Definitions by relative to true one;

Solved problems by marking scheme;

Change each activity every 15-20 minutes;

To use interactive board no more than 30 minutes without pause;

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?
