Theme: The Nature Squad

To celebrate the tenth anniversary, Marjolein van der Gaag has written the book ‘The Secret of the Nature Squad’. The book is about Levi, Samir and Zoë, who secretly start greening their neighborhood and experience all kinds of exciting adventures along the way. During this edition, we are calling on all children to form a nature squad too, so that together they can take action for nature. You can already reserve the book through publisher Leopold. You can also take part in Outdoor Learning Day without the book.

Lesson package and competition

By registering, you will receive the lesson package, tailored to the lower, middle and upper grades. With the help of the lesson package, children discover what they can do for nature close to home. Nature education, as well as language, spatial orientation and mathematics, are covered, and the one and only forest ranger Tim from KRO-NCRV has another fun morning activity in store for the children!

IVN will raffle 50 nature squad packages among the participants! A package full of materials that your nature squad can use. Think of pocket magnifying glasses, identification cards, seeds and the exciting book ‘The Secret of the Nature Squad’ to make the day complete. Register by 16 March at the latest for a chance to win!
