Begin the lesson by introducing the concept of contact forces. Discuss how these forces are present in everyday actions, such as opening a book or playing sports.

Engage students with a question: 'Can you think of a time when you pushed or pulled something today?' This will help them connect with the topic personally.

Introduce the key concepts of contact forces through examples like pushing a shopping cart or pulling a wagon.

Use the video 'Forces and Motion – Magnitude and Direction' to illustrate how forces affect movement. This video helps students understand the principles of physics through relatable examples.

Watch the video 'Forces in Action on the Football Field – Quiz Edition' to see how contact forces are applied in sports. This video reinforces learning through a quiz format, making it interactive and engaging.

Discuss with students how they can observe contact forces in their daily activities, such as playing with toys or participating in sports.

Engage students in a hands-on activity where they classify different actions as either pushing or pulling. Use objects like toy cars and books for demonstration.

Use the 'Positions and Directions' assessment to have students describe the location of objects and navigate a grid. This activity helps assess their spatial awareness and understanding of directions.

Assign students to observe and record examples of contact forces at home, such as opening doors or playing with pets.

Provide the 'Describing Motion' assessment where students describe motion in various images. This helps reinforce their understanding of motion and forces.

Conduct a class discussion to review examples of contact forces students observed. Encourage them to explain how these forces change the motion or direction of objects.

Use the 'Measure and Describe Motion' assessment to evaluate students' ability to observe and describe changes in motion. This activity encourages analytical thinking and observation skills.

Have students reflect on how contact forces are involved in their favorite activities or hobbies. Encourage them to share their thoughts with the class.

Use the 'Review – Interactions and Forces' assessment to consolidate students' understanding of the unit. This comprehensive review helps them articulate their grasp of how forces influence motion.

Conclude the lesson with a quiz to assess students' comprehension of contact forces.

For an extension activity, encourage students to create a simple experiment demonstrating contact forces using household items.
