Xperiment is a site designed by the Canadian Center On Substance Abuse for teenagers. You can try-out drugs with an eyeball named Earl (that’s not a typo).
It’s entertaining and informative, and the way it’s set-up English Language Learners can develop a lot of vocabulary knowledge. You pick a word (“paranoia,” for example) and Earl the eyeball acts it out.
I’ll add it to my website under Health.
