Chemical Reactions Word Search
This puzzle holds the vocabulary of a chemical reactions unit: the reactant and the product, the catalyst, exothermic and endothermic, combustion and oxidation, the signs of a reaction, from fizz to a precipitate, and the baking soda and vinegar of the classic demo.
In a reaction, atoms are rearranged into new substances, but none are made or destroyed. Antoine Lavoisier showed this by weighing sealed vessels before and after, and it is why a chemical equation must balance, with a coefficient in front of each formula so the atoms on both sides match. Baking soda and vinegar make carbon dioxide gas, which is the bubbles. Iron reacts with oxygen and water to make rust, and a hand warmer uses the same reaction, sped up, to give off heat.
The colors of fireworks come from metals in the mix: strontium burns red, barium green, copper blue and sodium yellow. The browning of toast and seared meat is the Maillard reaction, described by the French chemist Louis Camille Maillard in 1912. Yeast turns sugar into carbon dioxide and alcohol by fermentation, which is what makes bread dough rise, and an enzyme in your saliva starts breaking down starch before you swallow.
