Chemistry isn't just something that happens in laboratories. It's happening all around you, right now! Every time you bake a loaf of bread, watch a candle flicker, or wonder why your silverware has gone dark, you're witnessing chemical reactions in action. The truth is, our everyday lives are one big chemistry experiment, from the kitchen to the garden to the medicine cabinet. So how well do you really understand the invisible forces that shape your world? This 13-question quiz will put your everyday science knowledge to the test. No lab coat required, just your curiosity!

Small pieces contain less water
Heat avoids large pieces
The Maillard reaction is a reaction we get when...
The Maillard reaction is a complex chemical domino effect between amino acids and reducing sugars, triggered by heat. It is the process responsible for the appetizing golden-brown color, rich aromas, and savory flavors in cooked foods like seared steaks, toasted bread, baked cookies, and roasted coffee.
Cooking foods like steak or toast
Mixing acids like vinegar and bleach
Mixing acids and alkaline materials
Freezing foods in the refrigerator

Electrolysis
Combustion
Photosynthesis
Condensation
Hydrogen peroxide bubbles when poured on a wound. What is the bubbling gas?
Carbon dioxide
Oxygen
Hydrogen
Chlorine
What makes self-rising flour different from regular flour?
It contains added baking powder
It contains more yeast
It is ground more finely
It contains sugar
What is the main chemical change when an egg is boiled?
The proteins unfold and link together, becoming solid
The egg absorbs salt from the water

The shell dissolves into the egg
Time to Stir Things Up!
Chemistry may not be your strong suit just yet, but don't worry, every great scientist started somewhere! The wonderful thing about everyday chemistry is that the learning opportunities are all around you: in your kitchen, your backyard, and even your jewelry box. Why not try the quiz again after reading through the answers? You might be surprised how quickly these fascinating facts stick with you. After all, curiosity is the most important ingredient in any reaction!
Nicely done! You clearly know your way around everyday science. You've got a good grasp of the chemistry that surrounds us, even if a few of the trickier questions slipped past you. You're the kind of person who probably knows why the bread rises and why the kettle gets crusty, and that's no small thing! Brush up on a few more fun facts, and you'll be the resident science expert at your next family dinner.
Outstanding! You aced this quiz like a true scientist. From the Maillard reaction to the mysteries of fermentation, you understand the hidden chemistry that makes our world tick. Your friends and family probably already come to you with their burning questions (pun intended!), and now you have the score to prove your expertise. Keep that wonderful curiosity bubbling. Science needs more enthusiastic minds like yours!
