Every October, the American Chemical Society hosts National Chemistry Week — a celebration of how chemistry improves everyday life, aimed at students, teachers, and the wider community. It's a natural moment to recognize the chemists and educators in your life with something useful and on-theme. Here are gift ideas and celebration tips that go beyond the disposable.

When is National Chemistry Week?

National Chemistry Week is held during the third full week of October, and it overlaps with Mole Day on October 23 — so the whole month is prime time for chemistry celebrations, classroom activities, and gifts.
