"Have you ever experienced being pushed or pulled by somebody?" "Have you encountered situations where objects were pushed or pulled?" "Have you been involved in pushing or pulling something or someone?" "In your experiences, was anyone hurt due to pushing or pulling? Read the listed learning targets below.

After unlocking the vocabulary words in this game, ask the learners to write a keyword related to the unlocked work or draw a symbol to represent the word in the third column of the Part 1: Force is any kind of push or pull that makes something move or change its position. It’s like the power that makes things happen when we touch them or even when we don't. Imagine trying to move a heavy box or kicking a soccer ball— you're using force to make them move or change direction! Force can do a few things to objects: 1. Make Things Move: When you push or pull on something, you make it move. o For example, if you push a toy car, it starts to roll across the floor. 2. Stop Things from Moving: Force can also make something stop. o Like if you stop pushing the toy car, it will eventually stop because of friction, which is another force that resists movement. 3. Change Speed: Force can make things move faster or slower. o For example, when you push a sled, it speeds up. If you push harder, it goes faster. 4. Change Direction: Force can also change the direction of something. oThink about kicking a soccer ball. The ball was moving in one direction, but your foot made it change direction and go somewhere else. 5. Change Shape: Force can also change how things look by bending, squishing, or stretching them. oIf you press down on a pillow, it gets squished. If you pull on a rubber band, it stretches. Rigid objects are those that are hard and do not change shape easily when force is applied. They stay solid and keep their form unless a very strong force is used. Physical Characteristics: Rigid objects are tough and sturdy. They are made of materials that don’t bend or squish easily. Example of Rigid Object: A rock, a metal spoon, or a When you push or pull on a rigid object, it resists changing shape. If you apply enough force, it might break or crack, but it doesn’t bend or squish like a soft object would. Soft objects are things that change shape easily when you apply force. They can bend, stretch, squish, or compress. Soft objects can return to their original shape  Physical Characteristics: Soft objects are made of materials that can easily change shape. They might be stretchy, squishy, or bendable. oExample of Soft Object: A rubber ball, a pillow, a spongy toy, or clay. When you apply force to a soft object, it bends, stretches, or squishes. Soft objects can go back to their original shape after the force stops, but some might stay deformed if the force is too strong Complete the table below by classifying the following materials if they are soft or rigid. What are the physical characteristics of rigid objects ?

Which objects are soft, and which are rigid? 1. Force: Force is a push or pull that can make an object move, stop, change speed, or change direction. It is the power that causes objects to do something when you 2. Movement: Movement is when an object changes its position from one place to another. It happens when force is applied to an object. 3. Soft Objects: Soft objects are things that can bend, squish, stretch, or change shape easily when force is applied. These objects are 4. Rigid Objects: Rigid objects are things that are hard and do not change shape easily. They resist bending, squishing, or stretching when force is applied. Force doesn’t just happen by itself. It happens when something is pushed or pulled. Let’s look at how force works: Push: When you push, you are applying force away from yourself. Example: When you push a door, you are applying force to make it open. Pull: When you pull, you are applying force toward yourself. Example: When you pull a wagon, you're applying force to make it move towards you. The strength of the force depends on how hard you push or pull. A strong force can move heavy things or cause things to speed up quickly. A weak force moves lighter things or makes things move  Strong Force: If you push really hard on a car, it will move. If you pull a heavy sled, it will move too. Weak Force: If you gently blow on a piece of paper, it might move a little. Or, if you lightly push a toy car, it moves slowly. How Force Affects Rigid and Soft Objects: 1. Rigid Objects and Force: When you push, pull, or apply force to a rigid object: The object resists bending or squishing. It might move, but it keeps its shape. If too much force is applied, the  Example: Think about a brick. If you push it, it won’t change shape, but if you throw it hard enough against something, it might crack or break into pieces. 2. Soft Objects and Force: When you push, pull, or apply force to a soft object: The object changes shape easily (it might squish, bend, or stretch). If you stop applying force, the object might return to its original shape, but not always. Soft objects are more flexible and can change form without breaking.  Example: Think about a rubber band. If you stretch it, it gets longer. When you stop pulling, it goes back to its normal shape. But if you stretch it too much, it might snap. Effects of Forces on an Object I.

A push is a force that moves an object away from you, while a pull is a force that brings an object toward you. Forces help us perform tasks like opening doors, lifting Examples of Push and Pull Forces in Daily Life: 1. Pushing a Door: When you push a door to open it, you are applying a push force, moving the door away from you. 2. Pulling a Wagon: If you pull a wagon, you're applying a pull force, moving the wagon toward 3. Walking: When you walk, your feet push against the ground, which helps you move forward. This is an example of a push force. 4. Lifting a Bag: Lifting a grocery bag involves applying a pull force to overcome gravity and lift the bag upward. 5. Using a Vacuum Cleaner: When you push the vacuum cleaner across the floor, you are applying a push force. The vacuum also pulls dirt inside with its suction, which is a pull force. 6. Opening a Drawer: To open a drawer, you usually pull it toward you, applying a pull force. I. Forces in My Everyday Life II.

Rigid objects are materials that are hard and don’t change shape easily. They resist bending, squishing, or stretching when force is applied. 1. Forces are Everywhere Forces are all around us, and we experience them in almost everything we do. Whether it's pushing, pulling, lifting, or stopping, forces are constantly affecting objects in our world. A force is simply a push or pull that can change the way things move, stop, or change direction. For example, gravity pulls objects toward the Earth, friction slows things down, and we apply force when we push a door open or pull a drawer toward us. 2. Impact on Daily Activities In our daily lives, forces play a big role in how we interact with objects. For example: Pushing a shopping cart: When you push a shopping cart, you are applying force to move it forward. The harder you push, the faster it moves. Pulling a rolling backpack: When you pull a backpack with wheels, you're using a pulling force to move Playing with friends: Whether you're playing tag or kicking a ball, you're applying forces to make the game happen. You push or pull to move objects or change direction in the game. 1. Why do we need to be aware of how the things around us are moving? 2.
