Virtual labs are not just a pandemic thing.
While the majority of kids will be back in brick-and-mortar classrooms by fall, that fact doesn’t relegate online learning to the digital recycle bin. Many schools don’t have robust in-person laboratory facilities, instead relying primarily on dry textbooks to teach difficult STEM topics. But even schools with quality labs can benefit from these innovative and flexible online simulations.
The following top virtual lab sites and apps are all free, highly engaging, and informative—and most don’t require registration. Since most browsers no longer support Java or Flash, sites built exclusively with those outdated technologies have been excluded.
