OBSERVATION POT: With these 12 portable observation containers, you'll be able to explore nature and encourage cognitive learning in your children. Each pot measures 3cm (1.18 inches) in height and 4cm (1.57 inches) in diameter making them an ideal size for average-sized critters and other elements of nature. Made from strong, non-toxic plastic, these jars can withstand a lot of use and will not easily break or deform. The screw-on lid will keep specimens secure and safe and won't come loose. MAGNIFYING LID: Each jar is equipped with a magnifying lid that helps bring you or your children a closer view of nature. Catch, study, and then release critters to observe details you'd normally not be able to see. The pots are long-lasting, durable, and entirely reusable to study many different creatures. The plastic is transparent offering you a complete view of your specimen and the floor of the pots has a grid design for measuring and comparing minibeasts or other samples of nature. EXPLORATION TOOL: This is a great set to encourage children to explore, be active, connect with nature, and enjoy more hands-on play. The containers are ideal for collecting/catching insects/other small critters, leaves, flowers, rocks, shells, and other minerals. You'll be able to learn alongside your children and find hours of fun in this one set. The lightweight bug boxes can easily be taken to parks, gardens, forests, woods, and even beaches to help develop an understanding of the world. STIMULATE INTERESTS: Inspire knowledge in kids and help stimulate their interests in exploration/learning. This set is perfect for classrooms looking to study nature, groups of children that want to explore, or even families wanting to learn together. You can even teach gardening with close inspection of seeds and watching them sprout. Great for schools, colleges, and labs. These pots would make a great birthday/Christmas present for any child helping to develop their early exploration skills.
