Buy some vegetable seeds and some examples of the final results and run a tasting session. Encourage pupils to grow their favourites.
Pick examples that are easy to germinate and grow and won’t wait until the summer holidays to ripen. Micro salads are really great for this sort of thing – cress and mustard are really easy to grow.
Germinating a bean in a glass jar has been a classic experiment in primary schools for about a million years.
Collect some tree seeds, acorns or conkers are great, plant them outside in pots. They will take longer to germinate but could grow into massive trees outliving the pupils. Where could they plant them?
Have a look at our wildflower resources, a great way to take science outdoors, increase your biodiversity and have a beautiful display in your playground.
