Sprouting and growing seeds does not require costly resources. Recycled containers make useful pots, as do mugs and other items from the cupboard. Seeds can be sourced from foods or from plants from the garden. Introduce numeracy aspects by recording the time it takes for seeds to emerge, measuring stem growth, or count the number of leaves and/or flowers the seedling produces. Mustard and cress seeds sprout and grow quickly, and are edible, making them ideal seeds for young learners.
