KCDA v1.10.0 and earlier have a certificate which expires 2021-10-22, at which point the older versions of KCDA will stop working with Lt. Customers performing manual updates of KCDA will need to update by 2021-10-22. Then automatic KCDA updates will happen when the computer is rebooted, or overnight

The in-person versions of the 19 Chemistry labs are available! 


The Chemistry Collection was developed in partnership with Vernier and originally consisted of 19 Distance Learning labs, designed and released during the pandemic. We are now completing the collection by adding a further 19 labs, which address the same topics but are designed for in-lab use. The labs in the collection address fundamental introductory General Chemistry topics, and the majority (17/19) use Vernier's Go Direct sensors to collect data in Lt. All of the labs have some form of example data to enable flexible teaching.
