The Covid-19 pandemic has taken aback everyone that led to living unexpectedly in an environment called the new normal. One of the sectors seriously affected by this health crisis is education. With no face-to-face classes until a vaccine has been discovered, the Department of Education-Philippines (DepEd) believed that education should continue in school year 2020-2021 through online and other alternative modalities. The teachers in a private sectarian school in Manila began preparing as early as June 2020 leading to the creation of a learning continuity plan. One of the subjects in the junior high school seriously affected in doing online teaching and learning is Science. This study aims to explore and understand the experiences and challenges of the junior high school Science teachers after one term or almost three months of teaching in the new normal. The study found out that Science teachers were prepared and the curriculum was modified. Instructional materials were enhanced and various challenges were met like student discipline, delivery and execution of learning tasks, limited time for the implementation of the competencies, and student participation. Keywords: teaching science online, challenges of online teaching, science teachers creativity, initiatives and opportunities . Abstrak: Pandemi Covid-19 mengejutkan semua orang yang menyebabkan hidup di lingkungan tak wajar yang disebut kehidupan normal baru. Salah satu sektor yang terkena dampak serius dari krisis kesehatan ini adalah pendidikan. Tanpa kelas tatap muka hingga vaksin ditemukan, Departemen Pendidikan-Filipina (DepEd) percaya bahwa pendidikan harus dilanjutkan pada tahun ajaran 2020-2021 melalui online dan modalitas alternatif lainnya. Para guru di sekolah swasta di Manila mulai bersiap sejak Juni 2020 yang mengarah pada pembuatan rencana pembelajaran berkesinambungan. Salah satu mata pelajaran di sekolah menengah pertama yang terkena dampak serius dalam melakukan pembelajaran online adalah IPA. Penelitian ini bertujuan untuk menggali dan memahami pengalaman dan tantangan para guru IPA SMP setelah satu semester atau hampir tiga bulan mengajar di normal baru. Studi tersebut menemukan bahwa guru Sains telah disiapkan dan kurikulum telah dimodifikasi. Materi pembelajaran ditingkatkan dan berbagai tantangan ditemui seperti kedisiplinan siswa, penyampaian dan pelaksanaan tugas pembelajaran, waktu yang terbatas untuk pelaksanaan kompetensi, dan partisipasi siswa. Kata kunci: mengajar sains secara online, tantangan pengajaran online, kreativitas guru sains, inisiatif dan peluang. DOI: http://dx.doi.org/10.23960/jpmipa/v21i2.pp146-162
