Hello Fellow Bloggers! Today I have another experiment to share with you. This experiment is more of a research. Its called what is sand made of. Thanks to Nanogirl I now know what sand is made of. Before I watched the video I remembered that in my old school ( American Academy School in Qatar ) we learned what sand is made of. My old school told the students during our science lesson that sand is made of broke-down particles of shells. These shells sometimes break down due to watter pressures or long lifes. Now lets see if this theory is right.
After watching the video I learned that sand isn´t just made of broke-down shells. Its made of a mixture or different particles. Nanogirl ran a magnet through the sand to see if the magnat would attract anything. Surpisingly it managed to pick up this weird black sand. That sand was iron from all the different types of rocks on the beach. Those rocks may have broke down just like the shells.
But I wonder What types of rocks have iron in them to be able to be attracted to the magnet? Thats for me to know and you to find out. I was about to do the experiment but had no sand. But here is the link to Nanogirls Youtube page if you want to learn and do more cool experiments: https://www.youtube.com/c/NanogirlSTEMactivitiesforkids
Kia ora Margaux. Thanks for sharing that piece of research on sand. Well done on another very informative blog post. Do you know the beaches in Aotearoa that have black sand?

I never knew that some beaches in New Zealand have black sand. Its probably the amount of iron those sand have. Im willing to do some research on that soon. Thank you for the thoughtful comment.
