Energy can flow and transfer from one place to another when it interacts with matter. As energy flows it can change from one form of energy to another, such as from light energy to heat energy. Energy can never be created nor destroyed and only flows from place to place and changes its form. The main source of all energy comes from the sun. Some forms of energy are electricity, light, sound, and heat. Electrical energy is what we use to turn on lights and use our microwaves. Electrical energy can flow within a system when a circuit is completed. A complete circuit is made of conductors that allow electrons to go through. Electricity can be used to create electromagnets, light, heat, and sound. Light energy is a form of energy that people can see. When light interacts with matter, it can refract or reflect. When light reflects, it bounces off matter. When light refracts, it first transmits through matter then the light bends or changes its direction. Sound is a form of energy that we can hear through the sound waves. The application of energy allows matter to vibrate. These vibrations move back and fourth quickly such as when we strike the strings of a guitar. Sound energy creates vibrations in sound waves and when these sound waves hit our ears we are able to hear. Sound waves can only travel through matter such as air, water and solids. Ice would not melt if heat did not exist. Heat energy is everywhere and can be transferred through the process of conduction, convection, and radiation. Heat energy impacts the process of the water cycle, wind cycle and other important processes here on earth.

EXPLORE Suggested time: Day 1 The Heat is On 1. Divide students into small groups and assign roles. 2. Review safety guidelines with students before starting activity. Assign group roles. 3. Provide each group with a copy of the handout: The Heat is On and materials they will need. Instruct groups to follow the directions from the handout. 4. When groups complete the station, provide them with the handout: The MATERIALS: Heat is On Survey. Each student will complete one.  Handout: The Heat is On (1 per student)  handout: The Heat is On Survey (1 per student)  one 4 in. (11 cm) aluminum pie pan (1 per group)  one clothespin (1 per group)  10-15 chocolate chips (1 per group)  tea light candle (1 per group)  matches (for teacher) Safety note: Instruct the students to be careful of the candle flame. They should pin hair back and keep clothing away from the flame of the candle. 5. After students complete the activity, have them write what they have Science Notebook; learned into their notebooks. Write what was learned. Note: Make sure to light the candle for the students and talk to them about their safety and about fire. Look at step 3 from the handout: The Heat is On. Note: The candle flame needs to be positioned so that the first chocolate chip in the row receives the most direct heat. Heat should transfer slowly down the row as the metal transfers the heat energy to the other chips. ©2009, TESCCC 07/08/09 page 5 of 66
  6. 6. th 5 Grade Science Unit: 02 Lesson: 01 Instructional Procedures Notes for Teacher EXPLAIN Suggested time: Day 1 1. Ask:  What form of energy was applied to the pan and the chocolate chips? The form of energy was heat.  Why did the chocolate chips start to melt at different rates? MATERIALS: The front side of the row had more direct heat added to it.  Handout: Transfer of Heat Energy  Was there a transfer of energy? (1 per student) Explain or show illustration on how energy transferred from one piece of matter to the next. 2. Say: Heat is a form of energy. Heat was transferred through matter which was the aluminum pie pan and the chocolate chips. Heat is transferred through radiation, conduction, or convection. In this lab, heat (energy) Note: The handout: Transfer of Heat transferred through the process of conduction. Conduction occurs when Energy will allow students to heat is transferred by direct contact of molecules. The molecules in hot understand how heat transfers through substances move fast and collide with cooler slower molecules and the process of conduction, convection, transfer energy. and radiation. Students should be able to differentiate between the types of 3. Distribute a copy of the handout: Transfer of Heat Energy to each transfer of energy, but not necessarily student. learn the terms until a later grade. 4. Go over the handout: Transfer of Heat Energy with students. Ask:  Do metals transfer heat well? Why? Why Not? Metals are good conductors of heat and they allow heat to transfer Note: Make sure not to confuse well; explanations may vary.. students with the terms transfer and transformation. Transfer means that  Does the transfer of energy allow it to flow within matter? How? heat is transferring from one medium to Heat energy transfers within matter allowing heat energy to flow. another. Transformation means that the energy transforms into another form of energy. You many use the example of the movie “Transformers”, in this movie the cars totally transform into another robotic object. 5. Each student should write what they learned in their notebooks.

EXPLAIN Suggested time: Day 3 1. Ask:  What did you observe when you placed the tuning fork on top of the cup? The pepper seemed to move.  What made the pepper seem to move? The vibrations of the tuning fork and the waves that traveled through the air caused the pepper to move.  What happened when you placed the tuning fork at the bottom of the cup?  What happened when you placed the tuning fork on the plastic? The sound energy (vibrations of the tuning fork) transformed into the cup and the peppers.  What form of energy did we use to make the tuning fork vibrate?  What form of energy occurred when the tuning fork vibrated?  Was there a transformation of energy when the tuning fork touched the plastic?  What type of energy occurred? Mechanical energy transformed into sound energy when the tuning fork hit the heel of their foot. The sound energy then transformed into mechanical energy when the peppers started to move.  Why did the different straws have a different sound?  What caused the straws to make a sound? The size of the straws created a different pitch and the vibrations were created while they blew on the straws.  How would blowing on a flute, hitting a drum or playing a guitar be different and similar? The similarities would be that these instruments create sound energy by vibrating and allowing the waves to travel through matter. The differences would be the type of matter vibrating and the instrument itself. ©2009, TESCCC 07/08/09 page 8 of 66

  28. 28. th 5 Grade Science Unit: 02 Lesson: 01 How to Create a Solar Cooker 1. Get a shoe box and create a focal length about 1/3 deep into the box. Draw an inclined curve up into the box to make it look like a ramp. Cut one side of the box with scissors. Make sure to use the same piece to cut the other side so that the box can have the same sides. 2. Cut out a piece from a poster board that will fit the top of your opened box. Place the shiny part of the aluminum foil on top of the piece of poster board. 3. Place the piece of poster board, with the aluminum, on top of the opened box and tape it from the sides by using masking tape. Make sure that you do not leave that many opened gaps and do not bend the foil. Keep the foil as smooth as possible with its shiny side up. 4. Cut out two pieces of cardboard and place them on the sides of the shoe box. This will support your skewer. ©2009, TESCCC 07/08/09 page 28 of 66
  29. 29. th 5 Grade Science Unit: 02 Lesson: 01 Dancing Pepper (Station 3) 1. Place plastic wrap on top of the cup. 5. Strike the tuning fork again, while you pick up the cup, and allow the tuning fork to touch the bottom of the cup. Write down what you observed and explain why this happened on the Dancing Pepper Survey handout. 2. Add a pinch of pepper on top of the plastic. 3. Grab a tuning fork and strike it on the bottom of your soft soled shoe. 6. Strike the tuning fork the third time, allow it to touch the plastic on top of the cup. Write down what you observed and 4. Place the tuning fork right on top of the explain why this happened on the cup (do not allow the tuning fork to Dancing Pepper Survey handout. touch the plastic or pepper). Write down what you observed explain why this happened on the Dancing Pepper Survey handout. ©2009, TESCCC 07/08/09 page 29 of 66
