Life Science Word Search
This life science puzzle covers the elementary and middle school unit: living things and nonliving ones, the life cycle of a frog and a butterfly from tadpole and caterpillar to chrysalis, and the animal groups, mammal, reptile, amphibian and insect.
Scientists check seven things to decide whether something is alive: it moves, breathes, senses, grows, reproduces, gets rid of waste and takes in food. Students often remember them as MRS GREN. A crystal can grow and a flame can move and use up oxygen, but neither one does all seven.
Metamorphosis was a mystery for a long time, and many people believed insects simply sprang from mud or rotting meat. Maria Sibylla Merian raised caterpillars herself and painted each stage on the plant it ate; her book on the insects of Suriname, published in 1705, showed egg, larva, pupa and adult in order. Inside a chrysalis most of the caterpillar breaks down, and small clusters of cells that were waiting all along build the wings, legs and eyes of the butterfly.
