This study aims to develop the use of teaching aids in electric field learning videos to support discovery learning in high school. This research method uses the ADDIE development research method which includes five stages, namely analysis, planning, development, implementation, and evaluation. The instruments used in this study were validation sheets and questionnaires. The use of teaching aids in electric field learning videos has a percentage of product validity by material expert validators of 80% in the very appropriate category, media expert validators by 77.5% in the appropriate category, and learning expert validators by 82% in the very feasible category. Trials on high school physics teachers obtained a validity percentage of 94% and trials on students obtained a validity percentage of 83.2% with a very feasible category. It can be concluded that the use of teaching aids in electric field learning videos to support discovery learning in high school has met the eligibility criteria as a tool in the electric field learning process.","PeriodicalId":19083,"journal":{"name":"Natural Science","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78095026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method used is descriptive method with the type of research correlation study. The data collection technique in this study used a questionnaire and observation techniques. The population in this study were all class VII students of SMP Negeri 3 Lubuklinggau, totaling 314 students and the research sample was class which was taken by random sampling. Learning independence under study is learning independence with indicators of responsibility, strong self confidence and creative thinking. The data collected were analyzed using product moment correlation. The correlation between independent learning and science learning outcomes is = 0.5 which is in the very low category. Based on the results of data analysis t-count = 2.66 and t-table = 2.080 because t-count > t-table, it can be concluded that there is no positive and significant relationship between student learning independence and student learning outcomes of class VII SMP Negeri 3 Lubuklinggau academic year 2020/2021.

Some of the criteria for plants that are able to accumulate pollutants are found in parasol sunshade plants. Direct contact of plants with air pollutant particles certainly affects plant leaves because the leaves will show phenotypic plasticity in response to abiotic stress. Therefore, research has been carried out on the morphological characteristics of parasol sunshade leaves as a greenery plant in the city of Padang. The study was conducted in September 2021. Samples were taken from two different locations, namely the Padang State University area and Andalas University. At each location samples were taken from 20 individuals and observations were made at the Botanical Laboratory, Department of Biology, FMIPA, Padang State University. Data were analyzed using t test with a significant level of 5%. The morphological characters of the parasol leaf in the Padang State University and Andalas University area showed significant differences in terms of leaf stalk length, number of leaflets in one petiole, number of leaf branches, and were not significantly different in leaf length and leaf width.","PeriodicalId":19083,"journal":{"name":"Natural Science","volume":"196 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83507283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hypothesis has been put forward that the Tunguska Cosmic Body was an ice comet and its fall was accompanied by the fall of smaller fragments, whereas the TCB and fragments fell from intermediate Earth orbits. This explains all the observed phenomena without exception, including those that occurred long before the catastrophe. In this paper, we present eyewitnesses’ reports and objective materials obtained in the event area and con-firming the TCB passage in the direction from West to East. The western trajectory has been traced for 3500 km from the Volga to the Lower Tunguska. We have carried out a detailed analysis of the eyewitnesses’ reports revealing the circumstances of passage of a huge fireball. We provide criticism of trajectories constructed without taking new information into account. We have estimated the energy released during this event and determined the me-chanical properties of the comet matter. Science may obtain with new objects to study the direct impact of the comet matter on the Earth’s surface. This may be useful for evaluating the comet-related hazard.","PeriodicalId":19083,"journal":{"name":"Natural Science","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75028142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
