Comparing seahorses and seadragons (Record ID 424)
Seahorses and seadragons both live in oceans. They also both come in different shapes and sizes. They both have hard, rigid bodies and move very slowly. Both seahorses and seadragons reproduce with the males carrying the eggs instead of the females. Both can change colors to match their environment. Seahorses can grab onto plants while seadragons cannot.
Bees and plant growth (Record ID 438)
Bees help pollinate plants so they can reproduce. There are three different kinds of bees, and the queen bee is the largest. Bees keep their honey in their hives.
Plant growth and life cycle (Record ID 446)
Plants start out as seeds. Once the seeds get enough water and sunlight they produce shoots. These shoots develop into leaves and flowers until the plant is full grown.
Frog life cycle (Record ID 481)
The life cycle of a frog includes the egg stage, tadpole stage, froglet stage, and adult frog stage. Tadpoles live in water and use gills to breathe. They develop lungs as they mature into frogs and live on land.
Chicken life cycle (Record ID 486)
A female chicken is called a hen and a male chicken is called a rooster. Hens lay eggs as a way to reproduce. The egg then hatches into a baby chick and the chick matures into an adult hen or rooster.
Waxworms (Record ID 617)
Adult waxworm moths lay eggs. The eggs hatch into waxworm larvae. The larvae pupate and spin cocoons in which metamorphosis occurs. The waxworms emerge from the cocoons as adult greater waxworm moths. Adult waxworm moths can take over weak beehives and lay their eggs there. The larvae will eat the wax hives and destroy them.
