Begin the lesson by introducing the concept of force with a simple demonstration. Show students how a push or pull can move an object, such as pushing a toy car or pulling a drawer.

What is a Force?
Learning Objectives
- Define and differentiate between push and pull forces.
- Identify examples of push and pull forces in everyday activities.
- Explain how the strength of a force affects the motion of an object.
- Describe how multiple forces can act on an object simultaneously.
- Discuss how the weight of an object influences the amount of force needed to move it.
Introduction and Hook
Engage students with a question: 'Can you think of a time when you pushed or pulled something today?' This will help them connect the concept to their daily lives.
Direct Instruction
Explain the difference between push and pull forces using real-life examples such as opening a door or pushing a swing.
Use the video 'Pushes and Pulls' to illustrate how these forces are used in everyday life. This video provides relatable scenarios and interactive resources to help students understand the basic principles of motion and force.
Guided Exploration
Watch the video 'Forces in Nature' to see how natural forces like wind and water can move objects. This video connects the concept of force to real-world examples, enhancing students' understanding of how forces influence movement.
Discuss how multiple forces can act on an object simultaneously, such as when playing tug of war or using a bow and arrow.
Hands-On Activity
Have students participate in a hands-on activity where they classify objects around the classroom as being moved by push or pull forces.
Use the 'Measure and Describe Motion' assessment to explore how modifications affect motion. This activity helps students analyze and interpret results through hands-on experimentation.
Independent Practice
Assign students to observe and record examples of push and pull forces at home. They can draw or write about their observations.
Check for Understanding
Conduct a class discussion to review the different types of forces and how they affect motion. Encourage students to share their observations from the independent practice.
Review and Reflection
Reflect on the lesson by asking students to describe how the strength of a force affects the motion of an object. Use examples from the lesson to support their explanations.
Assessment and Extension
Use the 'Positions and Directions' assessment to evaluate students' understanding of spatial awareness and force application. This assessment encourages practical application of spatial concepts.
Encourage students to take the Unit Quiz to test their comprehension of the lesson on forces.
