Students will be building a glossary of the scientific vocabulary used throughout the pondpartners project.



Mrs. Hoffend's Fourth Grade Class September 2007
Science Vocabulary: (These terms will be studied throughout the year as part of our Pond Partners Project. The students will maintain a Pond Journal in which they record the definitions of the terms, and create illustrations or add photos to further enhance their understanding of the vocabulary words throughout the 2007-2008 school year. This will help to improve their performance on the New York State science test in May 2008 by increasing their exposure to and understanding of scientific terminology.

· Adult-the final stage in the life cycle of an animal
· Camouflage-way an animal hides itself. An example would be a cameleon.

· Frog spawn-the sticky eggs of a frog that float on the surface of the water; tadpoles hatch from frog spawn
· Gills-these are needed by animals to breathe underwater; they are outside the body fish have gills
· Hatch-when a baby creature comes out of its egg
· Lungs-organs that allow creatures to breathe air

· Tadpole-the small creature that hatches from a frog’s egg
· Amphibians-animals such as frogs that can live on land as well as water
· Carnivorous—meat-eating
· Herbivorous—plant-eating
· Omnivorous—meat and plant eating. Most people are omnivorous.
· Exoskeleton-an outer covering on a body, made of a substance called chitin. Sometimes they are shed do to growth.
· Hibernate—to rest or sleep during the cold months of the year.A period of cold weather inactivity, in amphibians, involves burying them self in mud or leaves.
· Larvae—grubs which eventually develop into adult insects
· Mammals—warm-blooded animals such as mice and rabbits we are mammals
· Mandibles—jaws of animals
· Molt—to shed the skin or exoskeleton
· Photosynthesis—the use of sunlight by plants to produce the energy to grow
· Pollen—the dusty powder produced by flowering plants
· Pollination—transferring the pollen from the male parts of a flower to the female parts of a flower
· Spawn—a mass of frog’s or fish’s eggs
