Forty classroom-ready science teaching and learning activities for elementary and middle school teachersGrounded in theory and best-practices research, this practical text provides elementary and middle school teachers with 40 place-based activities that will help them to make science learning relevant to their students. This text provides teachers with both a rationale and a set of strategies and activities for teaching science in a local context to help students engage with science learning and come to understand the importance of science in their everyday lives.
Activity 2: Germinating Seeds
Much like the embryo of an animal, growing inside its mother or in an egg, a seed contains a plant embryo waiting to emerge, grow, and develop into an adult plant. Unlike most animals, however, a seed has no one to protect it or feed it, so it must protect and feed itself. Thus, seeds have a hard seed coat for protection and contain food for the plant embryo to survive until it can grow leaves and begin to produce its own food through photosynthesis. Seeds wait until the environmental conditions are right before they begin to germinate, or grow. Seeds germinate when they absorb water, causing the hard seed coat to swell and burst. Seeds also need heat and light ...
