In Social Studies, third grade is studying explorers. Early European explorers used ships, called caravels, for their exploration. These ships had triangular sails and could easily sail into the wind. Students worked in collaborative groups in the Makerspace Classroom to build caravels from their choice of materials. Then they tested whether their caravels could float in the science lab. In this STEAM activity, students used art, science, engineering, and math concepts to successfully complete their designs.
