We find sand on beaches, sand dunes, timers, and in hydraulic fracturing, but what exactly is it? The video discusses the mineral that composes the majority of sand on the planet. It also explains how it forms and why it ends up near water or at least in large piles.
- Collect samples of sand from multiple places and compare them under a microscope
- Discuss other properties of quartz not mentioned in the video
- Public comment sections allow for vocabulary not typically accepted in the classroom
- ELLs benefit from closed captioning in nine different languages
- Graphics enhance the concepts through subtle imagery of key phrases
