Sowing Seeds: the Beginning of the Fast Plant Life Cycle
Students plant seeds, observe and tend plants. They identify major plant parts, how to germinate and troubleshoot problems with plants; and, that plants need water, light, and soil nutrients to thrive. They create a Plant Growth Data Log.
Curated OER
Compost and Composting Experiments
Students investigate the composting process through a variety of experiments. For this ecology lesson, students discuss the benefits of composting. They examine how compost affect plant growth.
Curated OER
Teaching Biology Through Problem-based Activities
Students plant seeds and observe the life cycle of the organism. They experimentally research the effects of radiation on seed growth. Students determine the effects of environmental pollutants on harvested seed.
Curated OER
How Do Green Plants Grow?
Students explore how seeds grow. They design an experiment and predict its outcome.

From Seeds to Plants
Second graders review the process of plant reproduction and the role of seeds in that process. The students dissect a seed, analyze their finds, collect and record data, and make predictions about seed germination and plant growth.
Curated OER
Seed Structure and Seed Dispersal
Third graders plant seeds. In this seed structure lesson, 3rd graders identify parts of a seed and plant a lima bean seed. Students discuss and reflect on the process in their journals.
