Then research to find scientists' inferences about the same type of fossil and evaluate their own inferences. Use plaster of paris to make imprints of various animals' footprints. They then compare and contrast the imprint with the footprint. Research a variety of endangered or extinct animals and infer reasons why they are endangered or extinct, then compare their reasons with those given by scientists. Human Body - Hearing and Speech People require an understanding of how their bodies work, how to protect themselves, and how to communicate effectively.
Students examine the structure and function of the organs involved in hearing and speech.
They identify what the organs require to work, investigate and explain ways to protect these organs from damage, and consider how technology has affected these organs. Students may construct models, create megaphones or telephones, or use sign language and speakers or other technologies to explore these organs and enhance their understanding of how to keep their bodies working properly. Suggested Learning Activities Create a megaphone and ear trumpet to investigate how a cone can be used to concentrate and direct sound. Collect assorted small objects found at home. Blindfold the child, then drop each object onto a table.
