Students use STEM skills to clean up a mock oil spill! Our kit includes an attention-grabbing card that introduces oil spills, 4 student booklets that help kids explore the issue in depth…plus materials for a real-world project. After conducting their research, students use a tray, foam pieces, absorbent fabric, oil dispersant and more to build a working oil containment boom. The kit comes with an extensive 24-page guide with 10 detailed lesson plans—from introducing the topic to assessing students’ final project presentations. Water tray measures 14 1/2".
