You can turn a handful of laser-cut plywood pieces into impressive 3D models with these IncrediBuilds kits. No glue is required—simply press out the parts and slide them together step by step—though each kit also provides suggestions for painting or embellishing your creation, and many include illustrated and entertaining fact books. Some of the parts are small, so we recommend these models for builders 8 and up.

That's no insect, it's a spider, and though creepy, these fascinating creatures are often misunderstood. Tame your own black widow spider with this 32 piece wooden model kit. It includes an illustrated book by Ruth Tepper Brown, formerly of the San Francisco Exploratorium, describing the spider's important role in our ecosystem and fun facts about different species, their anatomy, and the history of spiders in human culture.
