Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - 🔧 Starting an Elevator Startup

- Objective: Apply the formula for work done by gravitational force in a practical scenario and stimulate creativity in seeking sustainable technological solutions.

- Description: Students must assume the role of engineers in a startup that designs new elevator systems for a modern and sustainable building. They will need to calculate the work done by gravitational force for different floors and propose innovative solutions to increase the energy efficiency of the elevators.

- Instructions:

• Divide the class into groups of up to 5 students.

• Each group should choose a fictional building and define its main characteristics: total height, number of floors, and average mass of the elevators.

• Using the formula τ=mgh, each group must calculate the work done by gravitational force necessary to move the elevator from the ground floor to each floor.

• Then, each group should create a digital presentation (it can be a short video, slides, or a digital article) detailing their calculations.

• In the presentation, each group must propose innovative solutions to increase the energy efficiency of the elevator, possibly using renewable energy sources or smart technologies.

• Groups should share their presentations on a digital platform (such as Google Drive or Microsoft Teams) and allow classmates to comment and ask questions.

Activity 2 - 🏋️‍♀️ Fit Influencers and Gravitational Force

> Duration: 60 - 70 minutes

- Objective: Relate the concept of work done by gravitational force to everyday physical activities, using social media to engage students.

- Description: Students will become digital influencers sharing videos about the importance of physics in physical training. They must create content explaining how to calculate the work done by gravitational force in physical exercises, such as squats and weight lifting.

- Instructions:

• Divide the class into groups of up to 5 students.

• Each group should choose a physical exercise (e.g., squat, deadlift, vertical jump) and collect necessary data such as the mass of the practitioner and the change in height during the exercise.

• Using the formula τ=mgh, each group must calculate the work done by gravitational force during the execution of the chosen exercise.

• Then, each group should create a short video (using apps such as TikTok or Instagram Reels) explaining the concept and showing how to perform the calculations.

• The videos should be shared on a platform chosen by the class, and classmates should comment and provide feedback on the content.

• Conclude the activity with a brief discussion on the importance of understanding physics concepts in sports.

Activity 3 - 🎮 RPG Game: Gravity Mission

> Duration: 60 - 70 minutes

- Objective: Use gamification to apply physics concepts in a playful environment, developing students' logical reasoning and collaborative skills.

- Description: Students will be transported to a digital RPG game in which they must solve various challenges related to calculating the work done by gravitational force to progress in the mission and save a floating city.

- Instructions:

• Divide the class into groups of up to 5 students.

• Each group receives a link to a digital RPG game (it can be a simulation platform or an application created for the lesson) where they must save a floating city.

• During the game, students will encounter different scenarios that require calculating the work done by gravitational force to move objects or save characters.

• Groups must document their calculations and decisions in a digital logbook, which can be a shared document on Google Docs or Microsoft OneNote.

• At the end of the mission, each group must present their solutions and reflect on the importance of the work done by gravitational force in each situation faced in the game.

• Conclude the activity with a vote to elect the most creative solution and discuss the learnings from the experience.
