Young children are innately curious about the world around them and have a strong desire to find about world for themselves. The Science curriculum is an integral part of the Primary Montessori classroom and it helps to cultivate this curiosity. Children begin to understand about their environment first by observing and then experimenting with hands-on activities in the classroom. Some of the Science materials the child works with are magnetism, objects that sink and float, weights, vertebrate and invertebrates, living and non-living, and the classification and care of plants and animals. The child begins to expand his/her knowledge of nature through participating in outdoor activities such as going on nature walks, feeding the birds, planting seeds and flowers, investigating insects and spiders and observing plants and wildlife. As the child continues to ask questions about his/her observations, the desire to find out more information increases. Through the experience of nature studies, the child develops a sense of eager curiosity and the wonder of the world around him/her. This in turns helps him/her develop a lifelong interest and appreciation of nature and the Universe.
