From making a raft sink to getting a sea star to float, our innovative STEM Science Station is packed with hands-on experiments that help children explore and understand the science behind buoyancy! It includes 8 cards that prompt students to perform simple experiments…with all the hands-on materials to complete each one. Plus, the station features an engineering activity to extend the learning—and build critical-thinking and problem-solving skills! Includes a guide. The cards measure 8" x 8".
