Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the related scientific field?Stereochemistry, the study of the three-dimensional arrangement of atoms and molecules
2. Why can't my left hand and right hand be the same?Because they are chiral. Each hand has a unique arrangement that flips when you look at it in a mirror, so they never line up perfectly.
3. How did scientists learn about chirality?Scientists saw crystals twist light, and a scientist named Louis Pasteur split a crystal into two mirror shapes. He found each shape turned light in opposite ways, showing they were chiral.

Chirality: The property of having a non-superimposable mirror image, often referred to as 'handedness'.
Enantiomers: A pair of molecules that are mirror images of each other and cannot be superimposed.
Stereocenter: An atom (usually carbon) bonded to four different atoms or groups, leading to chirality.
Optical Activity: The ability of a chiral substance to rotate the plane of plane-polarized light.
