how it works

The program is a contest consistsing of two chemistry demonstrations shown to the students via a video and three fun, age-appropriate chemistry experiments that will be performed by the students at home. Each participant will answer a set of questions, submitted via a form posted on this website, after the demonstration and after each of the experiments.

The contest is open to students in grades 2-6; adult involvement is considered essential. Registration must be completed and submitted by September 19, 2021. Participation is limited to the first 200 entrants.

Many of the necessary materials for the experiments can be found in the home, but hard-to-find materials will be provided for free in kits via the library's branches during the week of October 10 -16. One kit will only supply one student. Students will perform the experiments at home during National Chemistry Week, October 17 - 23, 2021, and immediately thereafter. 


Prizes will be awarded to the top three submissions in each grade. 
  • 1st Place - $100 
  • 2nd Place - $75 
  • 3rd Place - $50 
Decisions made by the judges are final. Rules, contest instructions, the form for submitting answers and a video showing the chemistry demonstration and instructions for setting up each of the other five experiments will be posted on October 16, 2021.

Winners will be notified by mail as soon as possible after November 7, 2021. Each of the three winners in each grade will receive a letter of congratulations, a certificate suitable for framing and their check in the mail.
