Happy National Chemistry Week! This year’s theme is “Sticking with Chemistry,” a celebration of the science of glues and adhesives. It’s no coincidence that today is also Mole Day, the annual festival honoring Avogadro’s Number – the number of molecules or atoms that comprise a mole of a substance: 6.02 x 1023. That’s 602,000,000,000,000,000,000,000 molecules or atoms!
On the chemistry of glue, here’s an infographic from Compound Interest:
In terms of nanoscience and stickiness, it’s always fun to revisit our blog posts on ivy, Spider-Man, and gecko feet!
Looking for some sticky science to try at home? Here’s an ACS Reactions video (with consulting contribution from our own Dr. Alicia McGeachy!) all about making magnetic slime:
Finally, it’s hard to believe, but this is our seventh year posting on Mole Day and/or National Chemistry week! Here’s a little tour down memory lane:
- 2019: National Chemistry week & Mole Day: Marvelous Metals
- 2018: Mole Day (how many moles are in a cubic nanometer?)
- 2017: How many moles of gas are in a Pokémon Gastly? (Halloween post!)
- 2017: National Chemistry Week: Chemistry Rocks!
- 2016: National Chemistry Week & Mole Day (how a computational chemist uses moles)
- 2015: National Chemistry Week: Chemistry Colors our World/Mole Day & Enhancing Color: Quantum Dot Televisions
- 2014: Happy Mole Day from the CSN! (with doughnuts)
