For young naturalists exploring the nature of their homeland, few resources are as engaging and valuable as aquariums and terrariums. These essential tools are a must-have for any living corner and are incredibly useful in science classes. After all, no textbook or chart, no matter how well-crafted, can replace the experience of observing the living inhabitants of forests, ponds, and rivers. Of course, the best way to learn is to venture into the woods, fields, lakes, or rivers. However, winter doesn’t always allow for such adventures, and it can be challenging to observe the creatures of rivers and lakes when everything is covered in thick ice and snow. This is where aquariums and terrariums come to the rescue. Even in the depths of winter, during the harshest frosts, they offer a window into the underwater realm of fish, water beetles, snails, and algae, allowing you to discover the lives of various animals.
