• Create an image or infographic and write a caption explaining it for the post.

• Share the video and post with the class through the chosen platform (like Google Classroom or WhatsApp).

• Watch other groups' videos and provide comments emphasizing positive aspects and areas for improvement.

Activity 2 - 🔬 Data Scientists for a Day 📊

> Duration: 60 - 70 minutes

- Goal: Learn to manipulate and convert real data using scientific notation, and represent that data visually and informatively.

- Deskripsi Activity: Students will assume the role of data scientists, tasked with presenting a report on large sets of data using scientific notation. They will utilize Google Sheets to organize real data (for instance, the number of stars in the galaxy, bacteria in micrometers, etc.) and convert this data into scientific notation. Subsequently, they will create charts and infographics to visually showcase the results.

- Instructions:

• Form groups of up to 5 students.

• Research a relevant dataset involving extremely large or small numbers.

• Import the data into a Google Sheets spreadsheet.

• Use Google Sheets formulas to convert the data into scientific notation.

• Create charts and infographics to present the data visually.

• Prepare a brief presentation to explain the dataset and the created charts to their peers.

• Share the spreadsheet and presentation with the class via the platform chosen by the teacher (like Google Classroom or WhatsApp).

Activity 3 - 🌐 Space Mission 🚀

> Duration: 60 - 70 minutes

- Goal: Apply scientific notation in a practical and engaging context, while developing research, calculation, and data presentation skills.

- Deskripsi Activity: Students will be divided into teams, each responsible for planning a space mission. They will calculate distances between planets, sizes of celestial bodies, and other astronomical metrics using scientific notation. Using an online space mission simulator, they will test their calculations and finalize their mission plans.

- Instructions:

• Form groups of up to 5 students.

• Select a mission target (for example, traveling to Mars, or a mission to the Moon, etc.).

• Use credible websites to gather information on distances and sizes of celestial bodies in scientific notation.

• Perform necessary calculations for mission planning using scientific notation.

• Utilize an online space mission simulator (like NASA's Eyes on the Solar System) to verify calculations and refine mission plans.

• Prepare a presentation to describe the mission, the calculations performed, and necessary adjustments based on simulator outcomes.

• Present the mission and calculations to the class, emphasizing how scientific notation facilitated the task.

Feedback

Duration: 15 - 20 minutes

🔍 Purpose: The objective of this stage is to facilitate collective reflection on the learning journey and promote effective communication among students. This reinforces their understanding of the topics covered and aids in developing interpersonal and self-assessment skills. Through group discussion and 360° feedback, students will identify potential areas for enhancement and acknowledge their own growth, fostering a cooperative and ongoing learning environment.
