atoms and molecules are the main things in science atoms and molecules create what we know as matter.

natural and synthetic natural items are items that came from the earth and synthetic items are man-made and were created from natural items.
the law of conservation of mass means that mass cannot be created nor destroyed.
physical and chemical reaction a physical reaction means that an object's appearance is different but the molecules stay the same in a chemical reaction the matter and molecules are created into something new and different.
the periodic table of elements and the periodic table of elements is a graph of all the elements known so far.]]> 2021-12-16 21:40:29 UTC https://padlet.com/1567529/a1kcge27nj3srvt2/wish/1952659920 1567529 https://padlet.com/1567529/a1kcge27nj3srvt2/wish/1952664309 2021-12-16 21:45:15 UTC https://padlet.com/1567529/a1kcge27nj3srvt2/wish/1952664309 1567529 https://padlet.com/1567529/a1kcge27nj3srvt2/wish/2010131021
