Final Lp Science

Year: 6 Subject: Science Sub-topic: Simple Machines (Theme 5; Unit 6) Date: 4th October 2008 Time: 8am – 9am (1 hour) No. of pupils: 25 pupils (13 male; 12 female) Unit Goals:

Pupils should be able to: •

Recognize that system is made up of different parts that work together to perform a function.

•

Show an understanding that both living things and nonliving things have systems.

Learning Objectives:

At the end of the lesson, pupils should be able: 1. To recognize that a machine makes work easier. 2. To investigate the types of simple machines; levers, inclined planes, wheel and axles, gears and pulleys. 3. To identify the types of simple machine in everyday use tools. 4. To explore the activities on simple machines from the websites as their assessment in class. 5. To manipulate the simple machines to determine their uses and state at least 2 examples of the different types of simple machines. 6. To recognize the usefulness and limitations of simple machines, and appreciate its applicability in everyday life. 7. To answer at least 70% of the worksheet given, which have been diversify for slow, average and fast learners.

Materials:

1. Real objects: a. Scissors (Lever) b. Screw (Inclined plane) c. Mini plastic bicycle (Wheel and Axle, Gear)

2. Pictures: a. Stairs (Inclined plane) b. Flag pole (Pulley) 3. Computers (two pupils per computer) 4. Power point slides to be use during explanation. 5. Internet connection. 6. Worksheets for class work. 7. Video on Simple Machine. The Hook:

Teacher will show to the class, one by one, the real tools that the teacher brought from home and also some pictures of everyday use tools. Teacher will ask the pupils to identify the name of the tools shown and also state the function of the tools.

Exploration:

Pupils will need to investigate based on where, when and how those tools are used in real life. They may also think of any tools of simple machines that they know and familiar with. From here, the teacher will introduce to them the new concept that they will learn and give them the definition of simple machines and give them some examples by using verbal explanation and at the same time integrating IT in the lesson.

Practice:

Teacher will use the Power Point slides (See Appendix 1) to give further explanation about the types of simple machines which consist of: gears, pulley, wheel and axle, inclined planes, and levers. For each types of simple machine, teacher will provide them with pictures as examples and teacher will describe to them the functions of the machines in everyday life that makes our life easier. Teacher will also ask the pupils to predict the type of simple

Summary:

machine. When the pupils have seen some examples of simple machines and know their functions in real life, teacher will grouped them in pairs. Each group will be provided with 1 computer.

Teacher will help each group on how to browse the website in order to answer the online quiz for simple machine: http://www.coe.uh.edu/archive/science/science_lessons/scienceles 1/test.htm Then, after that, teacher will help them to browse the selected websites in order for them to play games on simple machine: http://www.harcourtschool.com/activity/machines/simple_machine s.htm http://www.edheads.org/activities/simplemachines/frame_loader.htm This game or activity about simple machines may give practice to them to investigate more about types of simple machines. In addition to that, the pupils will be more familiar to them and also the uses in our everyday life. Application:

Pupils are aware of the tools and its application usage in their everyday life. This lesson can enhance their awareness and they will be able to relate what they already know with what they have learnt.

Assessment:

There will be three different worksheets; for slow learners, average

The

learners and fast learners (See Appendix 2, 3 and 4). Oral questioning by selecting the pupils randomly (See Appendix

Aside from that, teacher will give the pupils another link, for them to learn in order to enhance their understanding on simple machine: http://www.beaconlearningcenter.com/Weblessons/SimpleMachines /default.htm
