Strange worlds right at your doorstep: Under stones, in compost, or in decaying trees live creatures whose shapes are as adventurous as their names: slime molds, stone crawlers, springtails. It's worth taking a closer look at them, even if they are already better known, like earthworms, flies, or earwigs. Because the better children know their environment, the more they will appreciate and want to protect it. With the magnifying glass, every small creature becomes an exciting discovery. First, the precise illustrations on the cards help in identifying the animals. However, to ensure that nothing is overlooked with the larger small creatures, children will find plenty of information and many suggestions for observations on the index cards: Where can you find the bristle pairs of the earthworm? How do earthworms reproduce? How does the land isopod breathe? What does a stone crawler eat? All texts are.
