Let ACS plan your next chemistry event for FREE!

One-hundred and fifty years ago, Dmitri Mendeleev first presented his periodic system to the Russian Chemical Society, forever shaping the way we look at the elements. His system, which organized the elements based on atomic weight, valence, and measurable properties, laid the foundation for today’s Periodic Table. In honor of this, The United Nations has declared 2019 to be the International Year of the Periodic Table.

View the recording now to celebrate IYPT 2019 and host an on demand party featuring one of chemistry’s greatest achievements. Explore the early efforts of scientists to organize the elements, meet a chemist who is expanding the table by discovering new superheavy elements, and answer  elemental “Table Trivia.” 

What Your Group Will Learn

  • What were the conflicting proposals from around the world for how the elements should be organized and why did our current system rise to the top
  • Be the hero of your next party with “Table Trivia” content created by C&EN and video production by ACS Reactions
  • How were the most recent, superheavy elements discovered and does the Periodic Table have any more room to grow
  • Much, much more...

Everything You Need to Host

What is ACS Program-in-a-Box?

ACS Program-in-a-Box is the easiest event you'll ever host because "it's all in the box."  With very little effort (acquire the space and gather the crowd), you can host an energetic science event that engages chemistry students and early career chemists.

Physical boxes are an exclusive benefit for active ACS-affiliated groups.  This includes, but is not limited to, groups hosted by ACS Local Sections, ACS Technical Divisions, ACS Student Chapters, and ACS members.  ACS International Chemical Sciences Chapters and ACS International Student Chapters are also now eligible!  If you have any questions about the status of your ACS group and your eligibility to receive a physical box, contact the ACS PIB team at


Not affiliated with ACS?  That’s okay! We want all chemists to join the party and connect with each other. We’ll send you a “digital box” to download handouts included in the physical box for you to print and share with your attendees. We can also help you use ACS Program-in-a-Box™ to start your Student Chapter, or get your Local Section or Student Chapter back into an active status, so next time you’ll see an ACS Program-in-a-Box™ on your doorstep!
