Did you know that the outdoors, teeming with plants, animals, birds and insects can transform into an immersive and captivating classroom? Nature Calls is a series of nature-based activities designed to encourage students to explore their surroundings, and stimulate their wonder and curiosity about nature.
Trees live close to us — in our backyards, gardens, fields, and road-sides. Their lives are intimately connected to the environment they grow in, an environment we know is changing. How are trees coping with the changing climate and weather patterns?

Students, especially in urban areas, do not get to spend much time outdoors and in nature. But, a small park, an empty or abandoned plot of land or garden in school or at home, even in a crowded city or town can transform into a nature hotspot! For example the bark of trees, leaf litter and shrubs are home to ants, mantids and spiders. Concrete walls and small water puddles can house moths, bees, wasps, dragonflies and even frogs!
