PROPERTIES OF MATTER AND ENERGY What is matter? Matter is anything that takes up space and has mass. Properties of Matter Mass Definition: the amount of matter in an object Tool for measuring: pan balance Volume Definition: the amount of space an object takes up Tool for measuring: graduated cylinder Weight Definition: the measure of the pull of gravity on an object Tool for measuring: spring scale Density Definition: how much matter is found in a certain space or how much matter is packed together; density depends on mass and volume Lesson Checkpoint: What is the difference between mass and weight? Special Properties of Matter Some matter has the capability of conducting energy, such as wires which conduct electrical energy. Some matter insulates against energy, such as a wood handle on a pot that insulates against heat energy so that you can hold a hot pot using the wooden handle and not get burned. Other properties of matter include magnetism which is the property of being magnetic (attracting iron or steel) and buoyancy, which is the ability of an object to float. © Copyright NewPath Learning.

Energy Energy is the ability to do work. Kinetic energy is energy that is happening now; it is energy in motion. The faster an object is moving, the more kinetic energy it has. The more mass an object has, the more kinetic energy it will have. Kinetic energy can change forms. For example, kinetic energy can change into heat energy when you rub your hands together. Potential energy is energy that is waiting to happen; it is stored energy. Examples of potential energy include a rubber band being pulled back or someone sitting on the top of the slide both have the potential to move, but have not moved just yet). Lesson Checkpoint: What is kinetic and potential energy? Forms of Energy Electrical Energy Electrical energy is the movement or flow of charged particles that care called electrons. Examples of electrical energy are electricity and lightning. Thermal Energy Thermal energy is energy related to heat. An example of thermal energy is geothermal energy, which is beneath the surface of the earth. Chemical Energy Chemical energy is energy stored in the bonds of atoms and molecules. It’s the energy that holds these particles together. Mechanical Energy Mechanical energy is the energy an object has due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion, like a rolling ball) or potential energy (stored energy because of an object’s position, like an arrow pulled back in a bow). Radiant Energy Radiant energy is energy that travels in the form of electromagnetic waves. Radiant energy includes visible light, x-rays, gamma rays, and radio waves.

How does heat get transferred? By conduction which is the transfer of heat between two objects that TOUCH. For example: When a metal spoon is put inside a cup of hot chocolate, heat travels from the hot chocolate to the spoon because the two are touching and because metal is an excellent conductor of heat. By convection which is the transfer of heat through liquid or gas. An example of this is a heated pool. By radiation which is the transfer of heat through electromagnetic waves, such as radiation inside a greenhouse.

5.1. What is Energy?
Energy is the ability to make an object move or cause a change in matter. You can't always see or touch energy, but it is everywhere. To find energy, look for motion, heat, light, sound, or electricity.
5.2. Energy for Life
We use many forms of energy every day. We use energy to heat, cool, run appliances, light our homes, and run our cars. We use the stored energy in food to keep us warm, maintain our bodies, and move about. Other living organisms need energy too. Plants use light, energy to grow and make food.
5.3. Energy from the Sun
The Sun provides most of the energy on Earth. Plants absorb light energy from the Sun and use it to make food stored as chemical energy. The energy stored in plants in turn provides the energy for other living things on Earth. The Sun's energy also provides warmth, powers the water cycle, and makes wind power.
5.4. Sources of Energy
The energy from the Sun also provided the energy to prehistoric plants and animals. When these living organisms died, their remains eventually became fossil fuels, named so, because like fossils, they lived long ago. Examples of fossil fuels include coal and oil. Fossil fuels are very important because when we burn them, they provide most of the energy we use every day!
5.5. Sources of Energy
5.6. Energy in Motion - Kinetic Energy
There are two main types of energy- potential energy and kinetic energy. Kinetic energy is energy that is in motion. A moving car, a bouncing ball, and a spinning top have kinetic energy. In contrast, potential energy is stored energy.
5.7. Stored Energy - Potential Energy
Energy that is stored and ready to go is potential energy. For example, a skier at the top of the hill who is not moving has potential energy, due to gravity. When the skier starts moving downhill, the potential energy changes into kinetic energy. Other examples include the energy stored in a stretched rubber band, food, and wood.
5.8. Potential or Kinetic Energy?
5.9. Chemical Energy
Chemical energy is potential energy stored in the bonds that hold matter together. It is released during a chemical reaction. Food has potential energy. When we digest food, the stored energy from the food is released in the form of kinetic energy and heat. Other sources of chemical energy include wood, batteries, and gasoline.
5.10. Sound Energy
Sound is kinetic energy that is caused by vibrations passing through matter. These vibrations can be carried by air, water, or solid objects. When you pluck a guitar string, the vibration of the string makes air move in waves. This causes movement of our eardrums and we can hear it as sound.
5.11. Light Energy
Light is a type of kinetic energy that we can see. Light is all around us and comes from the Sun, lamps, and many other sources. Light travels as waves in straight lines, except when it strikes an object. Then, it may pass through the object, reflect off of the object, or be absorbed by the object.
5.12. Electrical Energy
Electrical energy is kinetic energy that comes from electric current. Any appliance or device that is plugged into an electrical outlet uses electricity. Electrical energy changes to other forms of energy, like light, when the switch is turned on.
5.13. Thermal Energy
Have you ever wondered what makes something hot? All matter is made up of tiny particles called atoms. These particles within an object start to move as the temperature rises. The movement of these particles in matter produces thermal energy. We feel the flow of thermal energy as heat. Heat naturally flows from a warmer object to a colder object.
5.14. Transfer of Energy
All energy is connected and moves from one form to another. For example, chemical energy in gasoline turns into heat, sound, and motion as it burns. Energy from a soccer player's foot is transferred to the soccer ball as he kicks it, making it move. Energy cannot be made nor destroyed, but it can change form or transfer from one object to another.
5.15. Energy Flow in an Ecosystem
In an ecosystem, which consists of a group of living things and the environment in which they live, plants capture energy from the Sun. When an organism eats the plant the energy is then transferred to that organism. This process is referred to as energy flow. In this food chain example, energy flows from the grass, to the grasshopper, to the frog.
5.16. Energy Sources
The energy we use every day comes from a variety of sources. Fossil fuels, such as oil and coal, are nonrenewable. These energy sources can only be used once and cannot be replaced. Other energy sources, such as solar and wind power energy, are powered by sources that are naturally replaced and are considered limitless. These are called renewable energy sources.

6.1. Transfer of Energy
Energy comes in different forms and often we can change one form of energy into another. For example, when you eat food then take a walk, the chemical energy from the food turns into motion.Chemical energy can also change into other forms of energy. In the activity that follows, we will investigate if salt makes ice melt faster.
