Exploring Forces: What Makes Things Move?
Delve into the concept of forces and motion, understanding how interactions between objects cause movement. Discover the role of gravity and other forces in initiating, changing, or stopping motion. Engage in investigations and discussions to grasp key science ideas surrounding forces and explore real-life examples to deepen understanding.

FORCES LESSON 1B What Makes Something Start to Move?
Last Time How did you complete this sentence? My object, [name of object], started to move because _________________. When you share, make sure to tell us the name of your object, the other object that made your object move, the action that made your object start to move, and the action that made your object speed up, slow down, change direction, or stop.
Key Science Ideas 1. Something starts to move when something else pushes or pulls it. 2. An interaction between two objects makes something start to move.
Our Focus Question What makes something start to move?
An Important Science Word Scientists use an important word to describe what makes something start moving, change speed or direction, or stop moving. That word is FORCE!
Investigation: What Is a Force? Turn and Talk: Talk with your elbow partner about these questions: What is a force? What is gravity? You can look at the handout, but answer these questions in your own words.
Examples of Forces and Gravity What examples of forces and gravity can you come up with from your own life? Do two objects touch to make something start to move in your examples? If so, how? Use science words like these in your descriptions: Force Gravity Push Pull Twist
Key Science Ideas Forces are pushes or pulls between two objects that make an object start moving, change speed or direction, or stop moving. Gravity is a special kind of force that pulls an object toward Earth without requiring it to touch the ground.
Todays Focus Question What makes something start to move?
Lets Summarize! Draw a picture in your notebook that shows what makes something start to move. You can use an example from one of these: Today s reading Our investigation of different objects from the last lesson Your own life Use words from our word wall to label the force in your drawing that s making something start to move. Where is that force located?
Next Time In the next lesson, we ll look at a few of your drawings and see how you illustrated the forces that make objects start to move. Then we ll think about this question: How can we draw the forces pushing or pulling an object when we can t see them?
