Let's Learn Science: Chemistry for Cambridge IGCSE

Do you love Science? In this Ongoing Class, learners will explore a range of Science subjects in a fun and interactive way. This course aims to provide meaningful learning experiences for young explorers.

Each class will include a range of teaching methods and activities that are designed to engage the learners in both a hands-on and minds-on way. Classes will include experiments, Q&A, quizzes, games, worksheets, videos and much more. Some classes will include breakout rooms.  Learners will be encouraged to observe, explore, question and share what they learn. A variety of methods are used to support learners and cater for different learning styles and needs.
