Geology Rocks! pdf epub mobi txt 電子書 下載 2024
Design, build, and test quake-proof houses; perform scratch, streak, cleavage, and "perc" tests -- just like real geologists; go on a geological scavenger hunt; create models to observe the effects of water, erosion, and acid rain. Kids are challenged to consider geology in relation to things they use and their daily decisions.
