The Structure of Matter There is a large overlap of the world of static electricity and the everyday world that you experience. Clothes tumble in the dryer and cling together. You walk across the carpeting to exit a room and receive a door knob shock. You pull a wool sweater off at the end of the day and see sparks of electricity. During the dryness of winter‚ you step out of your car and receive a car door shock as you try to close the door. Sparks of electricity are seen as you pull a wool blanket

Title: States of Matter Introductions: In this activity you will investigate the physical science of the different states of matter. You are going to see how different atoms and molecules (types of particles) change state (solid‚ liquid‚ and gas) when they are heated or cooled. 1.

Subject:Chemistry Topic:States Of Matter What is matter? Matter is anything that has mass and occupies space. All matter can exist in three(3)states. There are: solid‚ liquid and gas. In addition‚ all matter is made up of particles: atoms‚ molecules and ions. Solids In the solid state state‚ the particles are packed closely together in a regular manner. The focus of attraction between these particles are very strong and as a result solids are usually very hard and very difficult to compress

The Nature of Dark Matter We observe the universe around us through many scientific means. However it is through the electromagnetic spectrum‚ that is everything from radio waves to gamma waves‚ that we learn about the objects in our world and beyond. However we can also learn about our universe through indirect means‚ such as the effect of gravity on light as well as larger objects like our galaxy. In fact it is this indirect method of observation that has led us to the discovery of extra-solar

Money Matters It’s no secret that schools in high-income communities are better than those in low- income communities‚ or the fact that students are being better prepared for desirable jobs. It’s astonishing to learn how huge the difference in education from wealthy communities and those from a poor community. In “Social Class and the Hidden Curriculum of Work” by Jean Anyon‚ Anyon observes five different schools for a whole school year of fifth graders; two working class schools‚ one middle-class

Chapter 2 The Components of Matter Elements‚ Compounds‚ and Mixtures: An Atomic Overview An element consists of only one kind of atom. An element is one kind of substance – the composition is fixed. Each element is unique because the properties of its atoms are unique. Molecules are structures containing two or more atoms chemically bound together. Diatomic molecules are two-atom molecules such as elemental oxygen. A compound is a type of matter in which two or more different elements are chemically

Family Matters The definitions of a family today and a family in the past are far from similar. The definitions may have some similarities but they have changed dramatically in many more ways. 50 years ago‚ families had rules that were stricter and families were closer in the sense of a relationship. Although some families today are more distant from each other and have fewer rules to maintain order‚ there are still some that maintain the same styles of the families 50 years ago. Families have
