The laboratory is an excellent learning environment that provides students with opportunities to engage in processes of investigation and inquiry. Recent research literature suggests that school science laboratories are the best environment for introducing students to central conceptual and procedural knowledge and skills in Science On the other hand, in the laboratory, meaningful learning is possible if the students manipulate equipment and materials in an environment suitable for them to construct their knowledge of phenomena and related scientific concepts Laboratory activities are a very important part of science education. A laboratory activity is most effective when it is carefully designed and structured by teachers. According to Hodson [The principal focus of laboratory activities should not be limited to learning specific scientific methods or particular laboratory techniques; instead, students in the laboratory should use the methods and procedures of science to investigate phenomena, solve problems, and pursue inquiry and interests The National Science Education Standards (NSES) in the United States and contemporary science education literature recommend inquiry as a method for learning and doing natural science in formal classrooms. Inquiry-based learning involves the process of questioning, exploring, and reflecting In learning environments that use inquiry, "learners can investigate the natural world, propose ideas, and explain and justify assertions based upon evidence Experimental design is a key step in inquiry-based learning. However, students cannot succeed in this step if they do not identify the equipment needed for different experiments. For that purpose, we have developed and
