|\eing an insect has its advan-

1 Itages and drawbacks.While yy food is usually easy to find, predators are almost always lurking nearby.You will get to test your luck at surviving as an insect in the Insectigations! game included on page 115, but first you need to create action cards. Action cards will be used to build the path, with instructions for moving your game token forward and backward as you try to be the first player to make it from egg to adult.

Materials

index cards Scissors Pen

Envelope

Cut the index cards in half so that you have 4 2K-by-3-inch

(6.3-by-7.6-cm) cards.Write the following actions based on insect anatomy onto the cards, one per card. Place all four cards (including the blank one) into the envelope for safekeeping until you are ready to create your Insectigations! game.

• You stumbled across a picnic! Roll the head die. If you have mandibles to carry away the crumbs, roll again.

• A hungry bird is looking for an easy meal. If a roll of the abdomen die shows you have an unprotected abdomen, go back to start.

• Here comes a fly swatter! If a roll of the head die doesn't show big compound eyes, lose one turn.

Although adult insects come in many shapes, sizes, and colors, at least they all have the same basic body plan. On the other hand, immature insects often look very different from each other, and even from their parents. Get ready to explore and understand metamorphosis, one of nature's greatest magic shows.

ost animals are born with all the body parts they will ever have and in the habitat where they will spend their whole lives. As animals grow bigger, they might grow fur or feathers, and move to a new place within a habitat, but most animals look and act pretty much the same their whole life.

Insects are different. Insects change. This process of change is called metamorphosis (met-a-MOR-fa-sis). Soft, white, wormlike grubs that hatch from their eggs will later emerge from stiff pupal cases as beautifully colored hard-shelled beetles. Striped caterpillars that creep along munching green leaves become winged butterflies, flying through the air and feeding on flower nectar. Algae-eating mayfly nymphs that breathe underwater through gills surface from the bottom of a pond or stream, split their skins, stretch their iridescent wings and fly away, never to eat again.

I I undreds of years ago, I I people didn't know where J-_L living things came from. They believed that frogs came from mud along the rivers, mice grew from spoiled grain, and flies grew out of rotting meat hanging in a butcher's shop. The idea that living creatures came from non-living items was called spontaneous generation.

Sp°ntane°ug Generation

Francesco Redi wasn't sure whether he believed in spontaneous generation or not. So in 1668, he did an experiment to see if fly maggots really came from meat.
