One of the most important factor differentiating natural sciences from other sciences is the importance attached to experiment and observation. The attitudes and behaviors of the people taught by experimenting, observing, researching and investigating will be highly different from the attitudes and behaviors of the people taught through classical methods (Taşkın Ekici, Ekici & Taşkın, 2002). It is accepted that laboratories have an important place in science teaching. Laboratory applications allow students to improve their scientific thinking and working skills and in this way make permanent and effective learning possible and impart the skills needed to plan new studies by making them recognize the importance of planned working (Altıparmak & Nakiboğlu, 2002; Soran & Özbaş, 1993; Şahin, Şahin & Özmen, 2000; Ceyhun & Karagölge, 2000). Teaching performed by doing and experiencing in a laboratory enable students to be involved in the process with all their senses. Due to the obligation of making cause and effect interpretations, it helps students to develop their performative and intellectual skills. Hence, it can be described as permanent type of learning (Tezcan & Günay, 2003). It is of great importance to plan the laboratory classes in compliance with the purposes of the course to achieve the objectives of the course.
