Solids, Liquids, and Gases Experiments Using Water, Air, Marbles, and More: One Hour or Less Science Experiments (Last-Minute Science Projects)

Award-winning author Robert Gardner comes to the rescue of busy students everywhere. Each experiment in SOLIDS, LIQUIDS, AND GASES EXPERIMENTS USING WATER, AIR, MARBLES, AND MORE follows the scientific method, and is designed to be completed in under an hour. Discover how to weigh air, estimate the volume of matter, and the science of why water holds together. There are also ideas for more science experiments if you have extra time.

Gr 5-9-These books all begin with the same dilemma: a student has procrastinated. His or her science project is due tomorrow, but there's a solution: projects that can be done in an hour or less. Unfortunately, many, if not most, of the items on the "What You Need" lists for several of the experiments are specialized. For example, in Atoms it is suggested that oleic acid be borrowed from a science lab; in Electricity, a microammeter is needed; Energy requires an immersion heater; etc. No sources for these items are given. There's another big problem for quick experiments: Many of the formulas often require prior knowledge on the part of students. For example, the complicated equation to determine the kinetic energy of a basketball in Energy results in "joules or newton-meters"-neither of which is defined. Attractive volumes, but not very user-friendly.α(c) Copyright 2011. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
