Matter and energy ppt

  1. 1. By: Mrs. MJ Patterson 5th Grade Matter and Energy
  2. 2. The “stuff” in the world can be roughly divided into….. If you take all the stuff in the world, you know that there are many different types Matter “stuff” Energy“is what makes the “stuff” moves.
  3. 3. Matter “stuff”. Anything that takes up space and has mass. Matter matter everywhere !!!!
  4. 4. Matter is the stuff around you. Matter is everything around you. Matter is anything made of atoms and molecules. Matter is anything that has a '''mass, weight, volume, or takes up space. Matter makes up everything from the mountains to the oceans to your fingernail and brain. Matter = “stuff” around the world.
  5. 5. MATTER MATTER CONCEPT MAP

  9. 9. AMOUNT OF MATTER IN AN OBJECT MASS DOES NOT CHANGE. MEASURED IN GRAMS MASS
  10. 10. USES A TRIPLE BEAM BALANCE TO MEASURE MASS. MASS DOES NOT CHANGE. MASS METRIC UNITS OF MASS: MILLIGRAMS, GRAMS, KILOGRAM
  11. 11. MASS WHICH ONE DO YOU THINK HAS MORE MASS?
  12. 12. BASED ON GRAVITATIONAL PULL ON AN OBJECT. WEIGHT CHANGES DEPENDING ON THE GRAVITATIONAL PULL. METRIC UNITS OF WEIGHT: POUNDS (LB.)

  21. 21. Electromagnetism The term "magnetic effect of current" means that "a current flowing in a wire produces a magnetic field around it". The magnetic effect of current was discovered by Oersted in 1820. He concluded that a current flowing in a wire always gives rise to a magnetic field round it. The magnetic effect of current is called electromagnetism which means that electricity produces magnetism. Guiding Question: How can you create a magnetic characteristic from a non-magnet material?
  22. 22. Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. Electrical conductivity tells us how well a material will allow electricity to travel through it. Many people think of copper wires as something that has great electrical conductivity. Thermal Conductors = a material that allows energy in the form of heat, to be transferred within the material, without any movement of the material itself. Conductors copper
  23. 23. Conductors Electrical and thermal conductivity are closely related. For the most part good electrical conductors are also good thermal conductors.
  24. 24. Conductors Different Types of Conductors (1) Metals are traditional conducting materials. You see them around the house all of the time. It's a metal wire or one of the metal prongs in an electric plug. There are a lot of free electrons in metallic conductors. Free electrons are electrons that are not being held in atoms, and so, can move easily. Some of the best metallic conductors are copper (Cu), silver (Ag), and gold (Au). There are some conductors that are not metals. Carbon is the best example. A solution such as saltwater has a lot of free ions floating around. Those ions (charged atoms) can flow easily, and ionic solutions are very good conductors. One of the reasons you need to get out of the water if there is lightning around, is that water normally contains dissolved ions, and if lightning hits the liquid (solution), it might conduct electricity long distances and electrocute you.
  25. 25. Electrical Conductors
  26. 26. Heat Conductors Heat passes through some materials easily and these materials are called thermal conductors. Heat loves to travel and will travel from a warmer material to a colder material. The heat will only travel from hot things to colder things and never the other way around.
  27. 27. Electrical Insulator Handling electricity can have very dangerous consequences, so it is necessary to insulate it from the surrounding environment. Therefore, conductors, such as copper wire, are wrapped in insulating material. Insulating material does not readily share electrons. Insulators are nonconductive materials that do not readily share electrons throughout themselves. Examples of these are most plastics and rubber, wood, glass and many ceramics. In general, many nonmetals are good insulators. There are always some exceptions (graphite fibers), so it is safest to test if a material is a good insulator.
  28. 28. Thermal Insulator
  29. 29. Thermal Insulator Activity Driving Question: Which cup can keep the heat longer – styrofoam, plastic, paper?
  30. 30. MATTER SOLID LIQUID GAS conductivity magnetism solubility mixture TEMPERATURE Boiling pt Freezing pt solution Melting ptdensity
  31. 31. DENSIT Y SINK OR FLOAT The density of a substance indicates how the particles of a substance are packed together within the substance. 
The tighter the particles are packed, the higher the density of the substance. Formula: Mass / volume =
  32. 32. DENSITY OF LIQUID SINK OR FLOAT Activity 1: What are some examples of liquid that is more dense than water? What are some examples of liquid that is less dense than water? Vegetable oil, water (red), dish soap (green), corn syrup, honey
  33. 33. DENSIT Y OF GAS SINK OR FLOAT Activity : Air and helium are both gas. Do they have the same density?
  34. 34. DENSITY OF SOLID SINK OR FLOAT Activity: Which material is the most dense? Popsicle stick; crayon; pasta; paper clip
