Melissa’s Green Machine The Carbon Footprint Challenge

Melissa’s Green Machine The Carbon Footprint Challenge
十歲可愛女孩Melissa對環保充滿熱情，為學校的科學日製作了一台「碳足跡計算器」，以展示日常活動中二氧化碳的排放量。她的裝置能測量用電、用水和汽車排放等，並教導同學們如何通過簡單的行為改變減少碳排放。Melissa的專案不僅成功，也激發了同學們對環保的興趣，她的科學熱情因此更加高漲。
Ten-year-old Melissa, passionate about nature and science, creates a Carbon Footprint Calculator for her school's Science Day. Intrigued by the concept of carbon footprints, she designs a device to measure CO2 emissions from daily activities. Nervous yet excited, she presents her project, inspiring classmates to make small changes to reduce their carbon footprints. Melissa's journey in environmental science begins, fueled by her curiosity and desire to protect the planet.
