I love Jenna's example above with the DNA extraction - that's super cool, right? Being able to do something so "science-y" with kitchen supplies can really inspire and empower kiddos. As she points out, it's not a slam dunk that our kids will have what they need, but providing alternative hands-on tasks, demos on video they can respond to, etc can work. I teach online science as my regular job (not just in the pandemic) and have found that it's never okay to insist on hands-on tasks because it's just not feasible/reasonable for a lot of kids with their home situation and environment. But I always provide the OPTION, often many, in a given module of study, so those that can or want to, can! Check out resources like the Exploratorium's "science snacks." https://www.exploratorium.edu/snacks Finally, I love the idea of solo sits too - basically any task that invites kids to step away from the screen, tune in, make observations... The smallest task can inspire much more. Asking students to go out everyday and somehow figure out which way the wind is blowing, for example. Or what the temperature might be without using a thermometer.
