Abstract

Studying the natural sciences is the task of the students. Science learning requires active student learning related to physical or mental activity. The purpose of learning science for children is to develop children's development and potential. In addition, the purpose of scientific learning is to develop individuals to become familiar with the field of science and develop the ability to use basic aspects to solve the problems they face. in learning. Scientific Basis of Elementary School Students The results showed that there were differences in students' understanding between source-based and non-source-based learning, based on supporting information in the form of observation, source-based learning, and between respondents in elementary schools. primary. school age, clearly learning with visual aids is more effective and easy to understand.

Abstract

The 5G signal technology in electromagnetic pulse networks has triggered a revolution in wireless communication. This wireless technology is more advanced than the previous wireless (1G, 2G, 3G, and 4G). An electromagnetic pulse is a form of electromagnetic radiation made up of both electric fields and magnetic fields moving in unison. 5G operates at a higher frequency than previous cellular technology. The article's main focus is on the link between a 5G signal and an electromagnetic pulse and how the characteristics of the electromagnetic wave affect the performance and range of the signal. Here will be a discussion of 5G operating ata higher frequency range, including millimeters, which provides an extremely high data speed and large capacity. Additionally, it discusses the debate over the health effects of 5G technology and electromagnetic waves, detailed the scientific and global health organization's view of the issue. Research continues to understand and maximize the potential of 5g technologies in coming up with faster and better connections, as well as how we can overcome te's challenges.
