Science stories kids actually want to read
Opening your story…
Riya and Kabir enter Ionora, the Kingdom of Ions, with their robot guide Sparky. Through glowing castles, electron-exchange bridges, and crystal lessons, they discover how atoms become charged: lose an electron to form a cation, or gain an electron to form an anion.
At a science fair booth called The Atom Detective Agency, Anika and Rohan learn atomic number, mass number, and isotopes — and how atoms of the same element can have different numbers of neutrons.
Tara and Neil explore the Atomic Explorer and learn Bohr’s atomic model — electron shells K, L, M, and N — plus electronic configuration, valence electrons, and how valency helps atoms combine.
A physical change alters shape, size, or state without forming a new substance (melting ice, cutting a lemon, dissolving sugar). A chemical change produces one or more new substances (toasting bread, burning wax, rusting iron). Some physical changes are reversible; chemical changes usually are not. In a closed system, mass is conserved in both kinds of change.
