Life Science in Grade 5 helps students explore living organisms, their environments, and the connections that sustain life on Earth. At this stage, learners study plants, animals, humans, and ecosystems in a way that builds curiosity and scientific thinking. By asking questions, observing, and experimenting, students begin to understand important concepts such as adaptation, food chains, and life cycles. Life Science also teaches the value of protecting the environment and respecting biodiversity. The assignments below are divided into starter, practice, and challenge levels, giving children opportunities to ask questions, gather evidence, and think critically. With Life Science projects, students prepare for deeper science learning while connecting classroom study to the natural world around them.
