The most important thing that students must have in the 21st century is a knowledge base and deep understanding and develop various other abilities. One of the abilities that students must have in the 21st century is the ability to think creatively, not least in learning science. Science learning is related to events that occur in nature. Therefore, a strategy is needed for teachers to build students' creative thinking skills so that students can gain the right knowledge.
