S8P2. Students will be familiar with the forms and transformations of energy. Explain energy transformation in terms of the Law of Conservation of Energy. b. Explain the relationship between potential and kinetic energy. c. Compare and contrast the different forms of energy (heat, light, electricity, mechanical motion, sound) and their characteristics. d. Describe how heat can be transferred through matter by the collisions of atoms (conduction) or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection).

S8P2A - Explain energy transformations in terms of the law of conservation of energy Label the following pictures with the type of energy used and created. Type your answers in the boxes Explain why this flow chart does not follow the law of conservation of energy.

b. Explain the relationship between potential and kinetic energy. Using the “Insert” tab and “shapes” selection, create bars that complete the bar graph to show the percentage of each PE and KE for each point.

c. Compare and contrast the different forms of energy (heat, light, electricity, mechanical motion, sound) and their characteristics. sound Mechanical motion light Moves along conductors Requires a medium Moving electrons heat electricity Does not require a medium Travels as a transverse, mechanical wave Travels as an EM wave Directions: Organize the pictures, titles and details into a chart. Each type of energy has three details that match. (You can delete these directions because you will need this space.) Also called radiant energy Can be from elastic PE Can be from gravitational PE Can be static or current Moves from areas of hotter to colder Transfers by conduction, convection or radiation Will transfer until it meets equilibrium Has a pitch and loudness Total KE and PE in a system

d. Describe how heat can be transferred through matter by the collisions of atoms (conduction) or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection). Type the correct type of heat transfer in the box. (Conduction, Convection or Radiation) 1. 2. 3.

S8P4. Students will explore the wave nature of sound and electromagnetic radiation. Identify the characteristics of electromagnetic and mechanical waves. Describe how the behavior of light waves is manipulated causing reflection, refraction diffraction, and absorption. Explain how the human eye sees objects and colors in terms of wavelengths. Describe how the behavior of waves is affected by medium (such as air, water, solids). Relate the properties of sound to everyday experiences. Diagram the parts of the wave and explain how the parts are affected by changes in amplitude and pitch.

Move the terms and descriptions into the correct locations on the Venn Diagram. EM Mechanical sound Transverse Need Mediums Can travel in vacuum Two transverse waves intertwined Radio waves vibrations longitudinal Ocean wave Seismic wave Light Tsunami transfer energy

use the word bank to Identify each behavior Describe how the behavior of light waves is manipulated causing reflection, refraction diffraction, and absorption. use the word bank to Identify each behavior refraction absorption reflection diffraction

Attach the words to the letter where they belong Sclera Optic nerve Retina Cornea lens pupil Iris Vitreous humor

answer the questions below Explain how each color of light is different from the next. Explain why the person sees this apple as red.

Describe how the behavior of waves is affected by medium (such as air, water, solids). Erase the question and answer the question by restating it. In what state of matter does sound travel the fastest? In what substance does sound travel the slowest? Using the chart. Why do you think that your voice is a higher pitch when you breath in helium?

Sound in a vacuum video- Click on the links, watch each video and describe what interaction happens in each. In order to click on the link, you will have to be viewing the slide show. Sound in a vacuum video- Doppler effect- Sonic boom-

Label each part of the wave in numbers 1-4. 1. 2. 3. 4.

Answer questions 1. How are waves A and B different? C 1. How are waves A and B different? 2. How are waves A and B alike? 3. How are waves C and D different? 4. How are waves C and D alike?

Answer questions. If these are representing sound…. B D C If these are representing sound…. How do waves A and B compare in pitch? How do waves A and B compare in loudness? How do waves C and D compare in pitch? How do waves C and D compare in loudness?

Use the clues and sort them into the circuit they best represent. parallel series One path Will work if a light goes out More complex wiring Multiple paths More efficient Will not work if a light goes out Brighter lights Dimmer lights Easier to wire Adding loads will add to total resistance Less efficient
