I apologize, but I don't have enough information to create detailed course entries for the Tajikistan Grade 1 Science curriculum. My searches revealed information about the education system in Tajikistan, including textbook information and general curriculum details, but not the specific content of the Grade 1 Science curriculum. I also found some information about USAID's Learn Together Activity, which aims to improve primary students' learning skills, including reading comprehension and critical thinking. However, this information doesn't provide the specific details needed for course entries. Therefore, I cannot fulfill your request at this time.
