Combine math, science, and history by building English trebuchets, Greek ballistae, Roman onagers, and more ancient artillery. Students follow the history of catapult warfare from the Vikings to Alexander the Great to the Crusades up until gunpowder was invented and catapults lost their favor as the weapon of choice. Each project includes a list of materials, step-by-step instructions, and diagrams. Most projects require some adult supervision.
