Students will need to look up scientific and related definitions. These definitions will be used in a game for the entire class. Finally, students will compile the definitions and word origin knowledge they have gained into a graphic presentation. Objectives Students will be able to: 􀀡 Define producer, consumer, omnivore, herbivore, carnivore, decomposer and scavenger 􀀡 Describe how words can be broken down into parts that are derived from root words and affixes 􀀡 Identify simple vocabulary building patterns of the English language 􀀡 Predict the meaning of root words and affixes based on understanding the definition of complete words 􀀡 Organize words by their roots 􀀡 Work as part of a team to achieve common goals 􀀡 Use a dictionary to look up and copy definitions of words with their parts of speech. Targeted Standard California English-Language Arts Standards, Grade 4 Reading 1 Students understand the basic features of reading. They select letter patterns and know how to translate then into spoken language by using phonics, syllabication, and word parts. They apply this knowledge to achieve fluent oral and silent reading Vocabulary and Concept Development 1.2 Apply knowledge of word origins, derivations, synonyms, antonyms, and idioms to determine the meaning of words and phrases. 1.3 Use knowledge of root words to determine the meaning of unknown words within a passage. 1.4 Know common roots and affixes derived from Greek and Latin and use this knowledge to analyze the meaning of complex words ([e.g. international](e.g. international)). California Science Standards, Grade 4 Life Sciences 2 All organisms need energy and matter to live and grow. As a basis for understanding this concept: b. Students know producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains and food webs and may compete with each other for resources in an ecosystem. c. Students know decomposers, including many fungi, insects, and microorganisms, recycle matter from dead plants and animals.
