AtomicTiles vs World Map Puzzle 168 Countries

Introducing Atomic Tiles: an Exploration of Atoms and Molecules, designed by Dr. Seth Bush, Assistant Professor, Department of Chemistry, Cal Poly University, specializing in Chemical Education and developed by Dr. Fred Ventura, Ventura Educational Systems. Atoms are nature's building blocks. Everything is made of atoms. Atomic Tiles is an active learning tool where students explore how atoms come together to form molecules. Using Atomic Tiles students begin to understand the structure of atoms. Students learn that an atom has a dense inner core called the nucleus that contains protons and neutrons. The outer layer of an atom contains the electrons called the electron cloud. Most chemical properties properties of atoms, including how atoms bond to one another, are the result of the outermost electrons in the 'electron cloud' known as valence electrons. Atomic Tiles depicts valence electrons as open or closed circles, similar to Lewis Dots. Open circles are electrons that can be shared to form bonds. Closed circles are electrons that are not shared. Targeted Development of Science Concepts in the Following Areas: Atomic Structure - Neutrons, Protons and Electrons Valence Electrons - Covalent Bonding Properties of Elements - The Periodic Table of Elements Building Molecules - An Interactive Exploration of Molecular Structures

==Let's learn the world map while playing the puzzle!== You can learn the countries in the world with a jigsaw puzzle. The world can be divided into six continents (41 nations in Asia, 42 nations in Europe, 49 nations of Africa, 16 nations of North America, 13 nations of South America and 7 nations of Oceania), and the puzzle can be enjoyed with each continent. ■Features ・From children to adults, even people who are not confident with geography, everyone can learn the size and position of the country with fun. ・The national flag will be displayed when you press each country. ・The country name will be read out when you release your finger. ・You can understand the shape of the country, location and the national flag. ・The time will be recorded upon completion. ・The fastest record of completion of each continent is displayed on the top page. ・Even small children can play easily since it only requires touching the scree with one finger. ・This application teaches concentration and gives a sense of accomplishment, and it also builds judgment and self-studying power.
