1. Energy Unit Week 32 Directions 1.Prepare your desk for science. Science notebook 2.Use voice level 0 (no voice) to read through your electrical energy notes from Thursday (notebook pg. 77).

2. Targets & Warm Up Targets: Students will understand how electrical energy is created. Students will identify the parts of an electrical circuit and their roles. Warm Up: What is electrical energy? What do you know about it?

3. Table of Contents DateTitlePage 5-8-15Electrical Energy78 Once you are finished with the Table of Contents, go to page 78 and add the title and date to the top of the page.

4. Atoms Atoms are the tiny building blocks of everything. Almost all atoms have three different particles. These particles have different charges. Proton = positive (+) Electron = negative (-) Neutron = no charge

5. Matter & Electric Charges Matter usually has the same number of positive and negative particles. Matter is neutral.

6. Electric Charges Charged particles can move between objects that are close to each other Static electricity Static electricity happens when positive and negative charges no longer balance (there is not an equal number). – Static electricity may move gradually or quickly electrical energy – Moving charges generate electrical energy, which changes into sound, light, and heat energy

7. Static Electricity Charged particles move between atoms in storm clouds Clouds become charged Static electrical energy is released as lightening o Heats up surrounding air (makes it glow) o Creates sound (thunder)

8. You can predict how charged objects will behave…

9. How Charged Objects Behave An electric force is the push or pull between objects that have a different charge A charged object can attract something that has no charge (neutral)

10. Balloon and paper are neutral with an equal number of positive and negative charges Balloon is negatively charged. Paper is neutral. Paper will move towards the balloon as the negative charges of the balloon pull the positive charges of the paper.

12. How do electric charges flow? Electric current = an electric charge in motion – Electric charge flows from one place to another – Travels quickly and invisibly Electric circuit = a path in which electric charges flow

13. Main Parts of an Electric Circuit Battery Wire Light bulb

14. Battery Energy or power source for the circuit Causes the electric charges to flow

15. Wire Provides a path through which the charges flow Insulated with a plastic covering

16. Light bulb Device that provides light Filament (resistor): a coiled wire that does not allow electric charges to flow through it easily. – The electrical charges heat up the wire and the wire gives off light. filament

17. Explaining an Electrical Circuit Video (2 minutes and 30 seconds)

18. Read about the different types of circuits Closed Circuit (pg. 379) Series Circuit (pg. 380) Parallel Circuit (pg. 381)

19. Reflection Questions How is electrical energy created? How does the energy from a battery get to a light bulb?

20. Targets (Revisited) Students will understand how electrical energy is created. Students will identify the parts of an electrical circuit and their roles.

21. Homework SubjectHomeworkDue Date ScienceNone You will have a substitute on Monday, and you will watch a Bill Nye Electricity Video. Heads up – energy quiz on Wednesday!
