The Frozen Project: a 6-year-olds study of crystals continues with help from @laksiyer…
When we started The Frozen Project @laksiyer suggested we study sand—so we did!
Where did you get your sand? Some came from the beach and some came from our sand box. I will call these Beach Sand #1, Beach Sand #2, and Play Sand #1.
What did the sand look like? Well some pieces of sand looked more square, some looked more like circles – they were unusual shapes. Mommy called them irregular. The sand acted like prisms and made miniature rainbows. (Though that is hard to capture on film.) I also noticed the sand looked like our wet snow samples.
Did the beach sand and play sand look different under your Foldscope? They almost looked the same, except the beach ones had tiny shell pieces in them.
How did you create your slides? Beach Sand #1 was made by sticking sand to tape/foldscope cover slip and then to a glass slide. I noticed the tape we used had texture and caused the sand images not to be so clear – so mommy suggested we try the foldscope cover slip. The foldscope cover slip made clearer images. Beach Sand #2 was made by picking up little bits of sand and putting it on a glass slide without a cover slip or tape. These were the clearest images so for Play Sand #1 we did the same thing: sprinkle sand onto the glass slide.
Here are my sketches:
