A DETAILED LESSON PLAN IN SCIENCE VI

I. Objectives:Given the necessary materials for an experiment, the pupils should be able to:

1. Identify, define the three simple machines, and state the differences and similarities in the use of simple machines.

2. Dissect a broken appliance or toy, and group according to category of simple machines

II. Subject Matter: Simple Machines: Lever, Wheel and Axles, ScrewReferences: BEC SCIENCE VIMaterials: Broken toys or appliances, screw drivers, pliers, hammer, worksheetsConcept: 3 simple machines1. Lever – a lever is a stiff bar that rests on a support called a fulcrum which lifts or

moves loads2. Wheel and Axle – A wheel with a rod , called an axle, through its center lifts or

moves loads.3. Screw- A screw is an inclined plane wrapped around a pole which holds things

together or lifts materials.

III. Procedure:Teacher Activity Students Activity

A. Pre-Instructional Activities1. Review (through game) (Force) Let us recall our past lesson about force and Pulley. Group yourselves into five(5) and each of you should cooperate. I will ask the 1st question, and the first group that will give the correct answer will be given a 1pt and they will ask a question that will be answered by the other groups.The group that will ask a question will be given a 3pts. The group that will answer correctly will be given a 2pts.

What is a Force?

(Facilitating)

Grp1-Ma’am force is pushing or pulling on an object we give its energy and cause it to move, stop or change direction(question to the other groups)

-Who is the scientist who introduced 3 basic laws of motion?

Grp2-Sir Isaac Newton(question to the other groups)

-Enumerate the 3 basic laws of motions?

Last Question for the group

End game

- Every time you move something, use your pencil, or walk, you are using force. These forces are examples of everyday life, because that is what a force is, everyday life. -Every day you use force to make your life easier. Sometimes it is hard to understand how forces help you.

2. Motivation- I will show you a picture, and tell me what can you see?

Picture A Picture B

Picture C Picture D

Grp3-the 3 basic laws of motions are Law of inertia, Law of acceleration, and Law of interaction(question to the other groups)

-What is the Law of inertia?

Group4

-All objects resist changes in their state of motion

-What is the law of acceleration.

Grp1-that heavier objects require more force to move the same distance as lighter objects.(question to the other groups)

-what is Law of interaction?

Grp2-that for every force there is a reaction force that is equal in size, but opposite in direction.(question to the other groups)

-What equipment did we use to show this motions?

Grp3-Pulley

-ma’am Picture A is a SHOVEL-ma’am Picture B is SEESAW

Picture E

-Have you tried riding in a Wagon or playing with the seesaw?-What is the use of a shovel?-Did you ever use a scissor before or a screw?

B. Presentation

-What you saw in the pictures are examples of simple machines.-Let us take two example from the picture

“the Wagon” Wagons are used for transporting people or goods.

“The Scissor” are use for cutting Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, thin plastic, cloth, rope and wire. Scissors can also be used to cut hair and food.

From the examplesWhat is a SIMPLE MACHINE?

1)Discussion

There are 3 types of simple machines:1. Lever – a lever is a stiff bar that rests on a support called a fulcrum which lifts or moves loads2. Wheel and Axle – A wheel with a rod , called an axle, through its center lifts or moves loads.3. Screw- A screw is an inclined plane wrapped around a pole which holds things together or lifts materials.

-ma’am Picture C is a WAGON-ma’am Picture D is a SCISSOR

-ma’am Picture E is a SCREWS

-Yes ma’am

-ma’am it is use for digging.

- Yes ma’am

-ma’am it is a machine that makes our work easier.

-Listening

2)Demonstration- We will watch a video clip (1:36sec) that will demonstrate and illustrate the different types of simple machines and its uses.

Title of video “Dr. Skateboard's Action Science - Simple Machines”

Downloaded: http://www.youtube.com/watch?v=72ZNEactb-k

- What are the simple machines that were illustrated and demonstrated by Dr. Skateboard in the video clip?

-How simple machine interrelated in the video to each other to function a skateboard?

-ma’am the Lever, The Wheel and Axle and the Screw

-ma’am the 1st type of simple machine that Dr. Skateboard introduce was the Lever which is found readily on a skateboard

It has an upturn area in front and as well at the back of the board

The upturn area access the lever for the rider and helps lessen the force excreted for the rider while jumping on an obstacles like rocks on the streets . it also act as a controller for the rider from moving from left to right.

2nd type of simple machine that Dr. Skateboard introduce was Wheel and Axle.It provides transportation and lifting power

And the 3rd type of simple machine that Dr. Skateboard introduce was the ScrewIt helps as a fastener for the board and the

-State 3 simple machines that you use in your daily life. Identify and its category of simple machine. Explain in 2-3 sentences why simple machines are important.

6) Assignment:I will give you a Rube Goldberg design brief on the task that you and your team members are to successfully complete.Go through the design process to help you complete the task. Make sure and choose a leader for your group. Also, choose a recorder to keep notes as you move through the process. Develop 5-10 questions along the way that can be answered before the product can be manufactured. This is a team effort. Everyone needs to be involved. Keep portfolio. In this you will have notes,stitches, ideas and questions CAD drawings and anything else for the completion of the task.

- when I wake up in the morning I use toothbrush to brush my teeth. It is a Lever.

- I ride my bicycle in going to school. It is a Wheel and Axle

- I use a bag which has a zipper for me to access my school materials easily when I need it. It is a Screw - simple machines make every day life a lot easier without a bunch of technology. It is a Eco friendly for our environment
