Simple Machines – The Safe Use of Simple Machines Basic 1 Basic Science Lesson Note

Learning Objectives:

By the end of the lesson, pupils should be able to:

• Say how to use simple machines safely
• Know the dangers of misusing simple machines
• Practice safe habits when using simple machines

Introduction:

Children, remember the simple machines we learned about? Today we will learn how to use them safely so we don’t get hurt.

Lesson Content:

Why We Need to Be Safe with Simple Machines:

• Simple machines can hurt us if not used properly
• They can cut, pinch, or crush our fingers
• Safe use helps machines last longer
• Following rules keeps everyone happy and healthy

Safety Rules for Different Simple Machines:

SCISSORS (Lever):

• Always cut away from your body
• Hold scissors properly with thumb and fingers
• Do not run while holding scissors
• Pass scissors to others handle-first
• Keep scissors closed when not cutting
• Never point scissors at anyone

KNIVES (Wedge):

• Only use with adult help
• Cut away from your fingers
• Keep knife on cutting board
• Wash and dry carefully
• Store knives safely away from children
• Never play with knives

WHEELS (Wheel and Axle):

• Check that wheels are not loose
• Do not put fingers in moving wheels
• Wear helmet when riding bicycle
• Look where you are going
• Stop bicycle properly
• Keep wheels clean and oiled

SLIDES (Inclined Plane):

• Climb up stairs, not the slide part
• Sit properly before sliding down
• One person at a time on slide
• Check slide is not too hot or wet
• Hold handrails when climbing
• Wait for person to clear bottom before sliding

SCREWS:

• Turn screws gently, do not force them
• Use correct size screwdriver
• Ask adult to help with screws
• Do not put screws in mouth
• Keep screws in safe container
• Be careful not to drop screws

PULLEYS:

• Check rope is not worn or broken
• Pull gently, do not jerk
• Make sure nothing is under heavy objects
• Ask adult help for heavy things
• Keep fingers away from moving parts
• Stand clear when lowering objects

General Safety Rules:

1. Ask for Help: Always ask adults when unsure
2. Use Correctly: Use each machine for its proper job
3. Keep Clean: Clean machines after use
4. Store Safely: Put machines away properly
5. Check First: Look for damage before using
6. Focus: Pay attention when using any machine

Class Activity:

Teacher shows different simple machines. Children take turns explaining one safety rule for each machine.

Evaluation Questions:

1. How should you pass scissors to a friend?
2. What should you wear when riding a bicycle?
3. How many people should use a slide at one time?
4. What should you do before using any simple machine?
5. Who should you ask for help when using knives?

Assignment:

At home, find one simple machine and practice using it safely with your parents. Tell them the safety rules you learned.
