Description:
Part of the Great Explorations in Math and Science (GEMS) series by the Lawrence Hall of Science, this unit of eight or more 45- to 60-minute sessions fosters scientific inquiry and critical thinking skills as students learn about acids and the pH scale, make "fake lakes" and determine how the pH changes after an acid rainstorm, present a play focusing on the effects of acid rain on aquatic life and hold a town meeting to discuss possible solutions to the problem of acid rain. Students also play a "startling statements" game and conduct a plant growth experiment to determine the effect of various dilutions of acid on seed germination. In addition to providing much information on acid rain. An orientation video is available online.
