Beginning 8 min 
At the beginning of the lesson, teacher introduces the students to the topic of the lesson, discusses with students LO of the lesson. Checking h/w and if necessary some of problems can be solved on the board. Starter: Teacher ask questions and pick students who will answer, rest can help and suggest their versions of answers. Review questions:  What is a capacitor?  What are the main parts of it?  Define capacitance?  What is the formula for the parallel plate capacitor capacitance?  Name the applications of the capacitors?

Activity 2: Task 1. Read the article on the link http://electricalschool.info/spravochnik/eltehustr/1509dljachegovjelektricheskikhcepjakh.html Students work in small groups and read the text and make notes in a form of table and title it. The teacher looks through the students' notebooks, as they are completed. At the end each group present 1 application of capacitors. Teacher can ask question or add some uses of capacitors. Activity 3: Energy stored in a capacitor Students watch a video and working in a small group or in pairs answer to the questions: 
laptops if available
headphones


10 min

Speaker from each group present the answer to the 1 question and teacher might complete his answer if it is necessary. Answers compared with the model answer: Teacher ask questions each group and might complete students answers in order to make sure that everything is clear to them. When all questions answered teacher gives a worksheet and students start to solve problems on a new topic. 1. A parallelplate air capacitor has a capacitance of 100 pF with a charge of magnitude 0.1 µC on each plate. The plates are 0.5 mm apart. 2. (a) What is the potential difference between the plates? (b) What is the area of each plate? (c) What is the electricfield magnitude between the plates? 9. A parallel plate capacitor consists of two 5.0 cm x 5.0 cm metal electrodes spaced 1.5 mm apart. The capacitor is connected to a 10 V battery. How much energy is stored in the capacitor? If students couldn’t finish solve these problems they continue it at home. 
Worksheets, calculators



Students write on sticker if they fully understand the topic, or if they write partially teacher ask them specify the question. Homework: repeat on the textbook, the material studied, and solve the problem 5.(a) Name the two applications of capacitors in an electrical circuit. 1................................................................................... 2.............................................................................. [2] For example, smoothing DC ripple, energy storage, blocking P.T. generator circuits, tuning circuits, synchronization circuits. (b) The figure shows a circuit containing a capacitor, a resistor of 12 kΩ, a switch and a sensitive ammeter. The capacitor is charged to a potential difference of 15 V. After the key is closed, the current in the circuit changes over time. Describe the relationship between the current in the circuit and the charge passing through a point in the circuit. ………………………………………………………………… [1] (i) Answer: the charge is equal to the strength of the current multiplied by the time of its passage. At the initial time, the charge on the capacitor was 3.3 x 103 μC, with a potential difference of 15V. Calculate the capacitance of the capacitor. C = ................................................... μF [2] Answer: 220 uF

End 2 min 
Reflection: Have students answer the following questions on post it notes or small pieces of paper.  What have you learned?  What remains unclear? What do you still need to work on? 


Differentiation  how do you plan to provide more support? What tasks do you plan to set for more capable students? 
Grading  how do you plan to check students' level of learning? 
Health &
Safety 

Support for students is planned to be provided through discussion of the created model of the reference scheme while working with the text of the article, then through checking the basic formulas by the teacher and advising while solving problems. 
Through observing by individual students solving problems during the lesson 
Creating a favorable psychological atmosphere, the compliance of tasks to the level of preparedness of students, the change of activities, counseling. 

What tasks do you plan to set for more capable students? 
Providing advice to students who have difficulty 

Students will: Most students will:
Some learners will be: 
Students can:  list the various applications of the capacitor;  know the formula of energy stored in a capacitor;  explain the meaning of the formula of energy stored in a capacitor;  apply equations for the energy of the capacitor in solving problems;
 explain how to find the capacitor energy when multiple capacitors connected in series or parallel
