“…So it requires the right approach to obtain maximum learning outcomes. This is supported by previous research which revealed misconceptions about the material of the human respiratory system, including research by (Dewi & Purnomo, 2021) which revealed that the percentage of students' answers to the material on the human respiratory system was 62.15%, who experienced misconceptions about the concept of structure and function of the human respiratory organs, respiratory mechanisms, respiratory frequency, respiratory volume and diseases or disorders of the human respiratory system in class VIII students from two classes at SMP Negeri 1 Sidoarjo. Factors that cause misconceptions include the students themselves, learning methods, ways of teaching and context.…”

Misconception is due to the distinct early concepts known to each individual from concepts agreed upon by experts and can cause a halt to the process of acceptance of new knowledge called misconception. One concept or science material which is considered quite difficult for learners because they are unable to discern for real the processes of the respiratory organs in the human body. The purpose of this study is to know the validity of the development of the human respiratory system e-module on conception level. This type of research and development (R&D) with the borg and gall model simplified to 4 stages of a basic, planning, development and testing. Data analysis shows the level of validity of the e-modules of the human respiratory system matter has an average of 69.16 % with the "valid" category. Small scale test analysis shows learners' responses to the use of the e-module learning media in learning have an 81.4% percentage that fall into the "very valid" category.

The purpose of this study to produce a learning media is spectro-animation used in learning Bohr atomic structure. Media spectro-animation consists of hardware integrated with animation software. This study used research and development (R&D) type Borg and Gall, through three phases: research design and literature studies, designing and manufacturing, and product development. Media spectro-animation is tested validation and feasibility tested by experts and chemistry teachers. The results of the validation got 94,5 and 94,0 average score with very good category. The final test product is done to 20 students of class X MIPA 1. There are increase understanding of the students' average score of 64 to pre-test mean score of post-test 81. The results of the t-test significance (sig) value 0.000 < 0.05, significant difference learning Bohr atomic structure before and after using the media. Feasibility by experts and chemistry teachers with indicators of effectiveness, efficiency and practicality media, each a score of 98,0 and 93,0 categories are very good. It can be concluded that media spectro-animation effective and can be implemented in learning Bohr atomic structure.

Refraction of light occurs due to the difference in the speed of light in the two mediums where the speed of light in a dense medium is smaller than the speed of light in a less dense medium. One of the refraction phenomena also occurs in prism glass. Prisms help scatter incoming light from monochromatic light sources. To prove this, refraction experiments can be carried out using a prism. Where the prism used is made manually using used glass made of acrylic. The prism that is made is then filled with water on the inside and a test is carried out to determine the refraction and the value of the angle of deviation. Based on the results obtained, the refraction of the prism glass made in where a beam of light that passes through the prism is deflected from its original direction, while the angle of deviation of the rays is proportional to the angle of incidence
