Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Simple Machines	5 mins	Briefly explain what simple machines are, emphasizing ramps and rollers. Use visuals if possible.
2	Group Discussion	5 mins	Facilitate a discussion about where students see ramps and rollers in everyday life.
3	Hands-On Activity	15 mins	In groups, students will create their own simple ramps and test different objects rolling down.
4	Exploration and Observation	3 mins	Students observe the effectiveness of different ramp designs and roller types, taking notes.
5	Wrap-Up Discussion	2 mins	Regroup to discuss findings, reflecting on how ramps reduce effort and can be used in real life.

Homework

• Students will complete a worksheet summarizing their observations from the hands-on activity, including drawings of their ramp designs and how they function.
• Collect and review worksheets without presentations, offering feedback through comments.

Assessment

• Assess understanding through observed participation in activities and completion of the homework worksheet.
• Provide feedback on their observations and conclusions in the worksheets.

Additional Notes

• Be prepared to assist students during hands-on activities.
• Ensure all materials are prepped before the lesson begins.
• Adapt discussions to accommodate various learning styles and abilities.
