1. What is conduction, convection, and radiation of energy?
Conduction - direct transfer of energyConvection – transfer in a fluid Radiation – electromagnetic waves
Wed 10/22
2. Draw and label greatest potential energy and greatest kinetic energy.
Mon 10/27

Tue 10/ 28
4. What ET’s take place in a Hydroelectric power plant?
PEKEMEEE
Mon 11/3
6. What is the name of the simple machine below?What is an advantage and disadvantage?Inclined planeAdvantage – less forceDisadvantage - distance greater
Tue 11/47. What type of simple machine is in the picture?How could you reduce the force needed to get up
the steps?Inclined planeLonger ramp
Wed 11/58. What energy transformations are taking place ?Kinetic or (mechanical) to thermalKE TE
Mon11/10
9. If its cold in the shade, what should you do?Us e the RADIANT ENERGY from the sun to get
warm.
Energy Quiz (if you want to raise to 70)Correct the questions missedOn you own paperFront 1. Write out question and correct answerBack 1. Draw image and write correct answer below
Page 1Draw and label flashlight p. 227Describe the energy transformations that take place.Page 2 How is energy transferred in each? Draw and explain.
CE>EE>LE>TE
CE>TE>LE PE>KE>ME>EE EE > ME CE > EE
Page 3 Explain the energy transformations. What happens to the spoon and tea?
Thermal energy is transferred to the spoon by conduction. Spoon gets warmer the tea cools.
What happens when hot rocks are put into cold water?
Conduction occurs , water getswarmer , rocks cool off.
Page 4 Draw and label p. 197
Page 5
Draw and label greatest PE and KE.
Page 6 What happens the higher you raise the first ball?
More potential energy the more kinetic energy.
Page 7 Which have potential energy, kinetic energy,
none or both? PENoneKEPE and KE
Page 8
What energy transformations take place in a Radio?
EEMESE
Page 9What will eventually happen to the ice tea? Room 80 o F
Will become the temperature of the room.
Room 80 degrees

What are some limitations of the models below?Too small to produce a usable amount of
electricity.
Slide 11How could you design an experiment to prove that
the more potential energy the more kinetic energy?
Record the speed of marble rolling down different height ramps. Speed = Distance / Time = cm/sec
