Description: Innovative investigations will empower students in grades 6 through 8 to explore the states of matter and changes of state - using inexpensive toys and common household items like balloons, paper bags, Silly Putty, facial tissues, and plastic Easter eggs. Classroom-tested and proven effective, these activities draw students in with toys, gadgetry, fun-to-do experiments, and observations of scientific phenomena in everyday events. Students will see solid rock candy form as a sugar solution evaporates; inflate a balloon using dry ice; and use the BedBugs game to learn about the behavior of solids, liquids, and gases. You'll find 24 motivating, reproducible projects in all - ready to use, and clearly referenced to the National Standards for Science Education, with comprehensive materials lists, procedures, content review, and extension activities included.
