The first law of thermodynamics is a physical law that governs the conservation of energy and heat transfer within a system. Energy - Cool It! is a kit that allows the demonstration of this law on an intermediate level. The included protocol enables students to plan and conduct an experiment on their own with basic guidance and allows the assessment of student learning capabilities. This kit contains all materials needed for 15 groups to perform their experiments, including a Teacher's Manual and a Student Study Guide copymaster.
