Artist Celia Curtis has an awesome job painting dinosaurs for large-scale puppet company Erth, and now you can learn all of her coolest tricks. She teaches kids how to draw the armoured beast that was the mighty stegosaurus here. And if that’s not Jurassic Park-sized fun enough, Royal Botanic Garden Sydney expert Joel Cohen leads a cute class about creating a teeny weeny dinosaur habitat in a terrarium here. Elsewhere you can get them thinking about the environment with walk-throughs on how to build a wind turbine, an insect hotel and a welcome spot for frogs in your backyard. If you don’t have a backyard, no drama. Just fold yourself a fabulous origami jumping frog instead. Or just let off some steam with this pop top volcano. Whatever you decide, you’ll find all these entertaining ideas and way, way more for free on the Australian Museum site.
