For internet videos, we have found Khan Academy to be useful.

ACS also has a number of resources:

for teachers (includes video demos that might be a nice alternative to actual experiments): https://www.acs.org/content/acs/en/education/resources/k-8.html

for students: https://www.acs.org/content/acs/en/education/whatischemistry/adventures-in-chemistry.html

PHET has a bunch of fun interactive simulations for most areas of science, including chemistry: https://phet.colorado.edu/
https://phet.colorado.edu/en/simulations/category/chemistry

I think he might really enjoy just playing with the PHET simulations, in particular.
