Bienvenue dans l'éducation pratique ! Aujourd'hui, nous allons explorer le sujet fascinant des graines et des cycles de vie, important dans le programme scientifique Key Stage 2 en Angleterre. Ce sujet aide les élèves à comprendre la structure et la croissance des plantes en utilisant des activités pratiques, du matériel de tous les jours et des tests équitables pour explorer l'impact de l'environnement. En comprenant la dispersion des graines et le rôle des plantes dans l’écosystème, nous pouvons cultiver une appréciation plus profonde du monde naturel.
Included Resources +
This pack includes seven activity sheets with accompanying lesson plans and a STEM Journal for recording plant investigations, observations, and discoveries across a full seeds and life cycles unit.
• STEM Journal — interactive notebook for recording plant investigations, observations, and discoveries
• Seed Hunt — outdoor investigation to find and identify different types of seeds
• Seed Dispersal — explore the amazing ways plants spread their seeds
• Copter Seed Investigation — investigate how winged seeds travel through the air
• Seed Expulsion Investigation — discover how some plants explosively disperse their seeds
• Seed Bomb — create seed bombs to promote wildflower growth and biodiversity
• Plant Lifecycle — understand the stages of plant growth from seed to flower

Curriculum Alignment +
Aligned to the Year 3 Science National Curriculum. Covers plants — identifying and describing the functions of different parts of flowering plants, exploring the requirements of plants for life and growth, investigating the way in which water is transported within plants, and exploring the part that flowers play in the life cycle of flowering plants including pollination, seed formation, and seed dispersal. Develops understanding of plant adaptations and ecology. Cross-curricular links to environmental science (Seed Bomb — biodiversity and wildflower habitats) and outdoor learning (Seed Hunt).
Teaching Tips +
Copter Seed Investigation is the standout activity — drop sycamore seeds and paper helicopter models from the same height and time how long they take to fall, varying wing length and weight to find the optimal design. Seed Bomb is a brilliant end-of-unit project — make them in spring and scatter them in a designated school garden patch, then observe germination over the following weeks. Seed Hunt works best in autumn when the widest variety of seeds are visible — take clipboards and STEM Journals outdoors and collect samples to bring back for classification. Seed Expulsion Investigation pairs naturally with slow-motion video footage of exploding seed pods (readily available online) to make the concept vivid before children investigate it practically.
