Mr. Smet’s Scientific Studies REVIEW OBJECTIVES & QUIZ BOWL

1. When an object slides down a hill, not all of its potential energy turns into kinetic energy. Explain this using the Law of Conservation of Energy. Why is this? DO NOW

The Law of Conservation of Energy says that energy cannot be lost or destroyed. When the potential energy does not entirely transform to kinetic energy, it is usually because of friction causing the potential energy turn into sound energy and thermal energy. DO NOW STUDENT RESPONSE

15. Which ball on the graph has the most potential energy? A 16. Which ball on the graph has the least potential energy? D 17. Which ball on the graph has the most kinetic energy? D 18. Which ball on the graph has the least kinetic energy? A 19. What is the law of conservation of energy?  Energy cannot be lost or destroyed. 20. What are four types of energies that can be transformed between?  Thermal energy, sound energy, light energy, kientic energy = 20 Joules – 15 = 5 joules – 10 = 10 joules – 18 = 2 joules

= 100 joules – 65 = 35 joules – 40 = 60 joules – 0 = 100 joules – 45 = 55 joules

SCIENCE – UNIT 5 QUIZ BOWL TESTING YOUR KNOWLEDGE FROM UNIT 5!

RULES OF THE GAME One clipboard & dry erase marker for every two people (take turns writing) You are only sharing answers with that one partner, not with your whole team Only write ‘A’ ‘B’ or ‘C’ on your dry erase board You will need a sheet of scrap paper for you and your partner (to do solve math problems on) When the teacher says “Boards!” your board must go, or your answer will not be counted

SCORING Teams will be divided up based on rows Even though you have a whole row as your team, you’re only able to share answers with your partner Whichever row has the MOST correct answers will receive the point for that round If there is a tie, both teams will receive a point
