Acids and bases are basic principles in science, especially chemistry which really needs to be learned for everyone, introducing the principles of acids and bases to children is very important to do so they love science more in the future. Dyes found in nature, especially those derived from plants, when they are in a solution, their color depends on the pH atmosphere, so they can be used as indicators or indicators of acids and bases in solutions. Introducing science from an early age means helping children to start thinking critically and logically. Science helps children experiment, explore and observe their surroundings. This slowly builds children's character to get used to thinking scientifically, is skilled at solving problems, and has high analysis. To introduce science to children, it needs to be packaged in an interesting way, one of which is science magic. To test whether the butterfly pea flower extract has a good pH range, it is first tested in solutions with all pHs from 1 to 14, and the results show that the butterfly pea flower has a good color range, while for scientific magic it is done by making three clear solutions that are not colored, each labeled A, B and C then the solution is given a butterfly pea flower extract and the results show three different colors, solution A is red, solution B is blue and solution C is yellow, in magic the solution A contains an acidic solution, solution B contains plain water and solution C contains an alkaline solution. The results of this study indicate that the quality of science learning media which is the magic game using butterfly pea flowers has the potential to be used as a medium for introducing science at the elementary school level. The conclusion from this study is that it is necessary to design the development of science learning media in the form of magic games to develop higher quality children's cognition so that they are very suitable for use in learning activities.
Feminism firmly stands in the front line when it comes to the confrontation against injustice and oppression. Yet, feminism has become too exclusive for the subject of women and privileged for sub-groups like whites and middleclass, who stand as a whole category. By then, feminism is stuck in a time warp as it is unable to diminish the oppression of binary gender and its exclusive category. Under the framework of post-structuralist feminism theory, post-feminism is defined as a positive development of feminism that offers the more comprehensive thinking. This research aims to identify the ideas of post-feminism and analyze how the shifting values of feminism towards postfeminism occur. Through interpretive methods, the researcher identified that post-feminism was about the deconstruction of the subject 'women' and inter-sectionalism. The millennial paradigm shifts in the United States allowed the creation of preferences that was diverse and unlimited to a specific gender perspective. Thus, the political preferences of feminists were not only limited to the assumption of women that should choose a female president. Therefore, supporters of the millennial wave phenomena of Bernie Sanders in the primary caucus of Democratic Party of US elections in 2016 became one of the reflections of the millennial post-feminism ideas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
