These cave drawings are called cross-section drawings, as if you cut open a mountain and get to see the section of cave that is inside. An ant farm gives you a cross section view of the tunnels that the ants live in underground. We show a model of an ant home as part of this project.
One of these cave home models shows a home for an invented family of cave men and cave women in ancient history. It is supposed to be (sort of) realistic. The other model is a fantasy cave home for a kingdom of dwarves.
Notice how both models are carefully colored and shaded so that you can tell what is rock and what is space for living, and how many details from the homes are shown.
Working on Projects at Home is different than working in school. We do not give you lessons or directions. We give you models of each project to look at carefully, and then you decide how to adopt the project for your interests, skills, materials, time, and any new ideas you have. Your project does not have to look like the models—it can be inspired by the models. If you are proud of what you created, we encourage you to share it online with the hashtag: #ProjectsAtHome.
