Student Task Sheet for Electronic Poster Project – Electronics Learning and Planning Your Design Name: _________________________________ See Rubric for Marking Scheme. Electronic Poster & Advertising Consider your favourite commercial, whether it be for clothing, a drink, a car etc.. Some of the best commercials have catch phrases or slogans that are short and simple for example, Subway, ‘eat fresh’ or Tim Horton’s, ‘Always Fresh.’ Q1-2 Re-sketch the Nike and Tim Horton’s logos above with colour. Q3 Can you think of another catch phrase that you like from a commercial and what company it’s from. Slogan,’_____________________________________ ___________________________________________________________ Q4 Company :__________________________________________________ Exploring Technology Slogans Over the past number of years students have designed slogans to promote the Integrated Technology Course such as; ‘Tech Will Put You On The Right Track’, by Josh Valente and, ‘Nothing Beats Tech’, by Nick Sullivan. Can you think of a slogan to promote the Integrated Technology course? Q5 ___________________________________________________________ ___________________________________________________________ Once you have completed your catch phrase, you must now consider how to promote your idea. For example, is your idea sport- related, car-related or other? The teacher will share with the class past Electronic Poster projects. Discuss them and notice how they have complimented their slogan with their poster. Preliminary Sketches Q6-11 Sketch your initial ideas below with colours, patterns LED locations. Electronic Posters, Light Emitting Diodes and Electricity LED’s or Light Emitting Diodes are very small bulbs that are more energy efficient than incandescent light bulbs. They are used everywhere from traffic lights to flat screen tv’s. Toronto Hydro is replacing their traffic lights with LED’s in hopes of reducing electricity use by 84%. LED’s last longer which reduces labour costs and since the failure of one LED does not cause the entire system to fail, it results in greater safety for motorists and pedestrians. 1 Q12 What does the acronym LED stand for? L_______________ E__________________ D__________________. Q13 Toronto Hydro is replacing their traffic lights to LED’s and by doing so it is hoped that they will slash electricity use by up to________%. Q14 Where would you find LED’s in your classroom? ____________________ Q15 Where would you find LED’s in your school? _______________________ Q16-20 Re-sketch the LED above and label it. Q21 Sketch a lightning bolt above. Man’s first attempt to understand electricity was over 2,000 years ago in ancient Greek mythology. Zeus, or the king of the gods was the most feared and respected of the Greek gods. When anything upset Zeus, the skies would turn black and the ruler of Mount Olympus would use thunder and lightning to his advantage. Q22 Sketch and label the Atom diagram above. In ancient Greek philosophy, the word Atom was used to describe the smallest bit of matter or is ‘not divisible.’ The atom is the smallest particle that makes up a chemical element. It consists of an electron (E-) cloud that surrounds a nucleus containing positively charged protons (P+) and electrically neutral neutrons (N). A Proton is a positively charged particle. + An Electron is a negatively charged particle.And a Neutron is a neutrally charged particle. Q23 Sketch the drop of water above. In fact, an Atom is so small that a single drop of water contains more than a million million billion atoms. Sketch the water atom here. Water (H2O) for instance, is made up of two kinds of atoms, Hydrogen and Oxygen. In fact, there are two Hydrogen atoms and only one Oxygen atom as shown above. Q24 When anything upset __________, the skies would turn black and the ruler of Mount Olympus would use thunder and lightning to his advantage. Q25 What is the Greek word for a non divisible bit of matter? ______________ Q26 A single drop of water contains more than a _______________________ __________________________ __________________________ atoms. Q28 Water is made up of ________________ and ________________ atoms. Electricity is concerned with positively charged particles, or protons that repel one another, and negatively charged particles or electrons, that also repel one another. Negative and Positive particles, however, attract each other, much like the North and South ends of magnets. This behaviour may be summarized as follows; ‘Like charges repel, and unlike charges attract.’ Q29 Rub two balloons on your clothes. If you place them besides each other, will they attract or repel? What is your conclusion? __________________ Brief Battery History The first Battery called the Voltaic pile was invented by the Italian physicist Alessandro Volta in 1800. Although much larger than today’s batteries, it used alternating copper and zinc discs with a wire through the middle. Today, you can buy many different sizes of batteries to suit different functions. From Disposable to Rechargeable, from Lithium and Alkaline batteries in sizes A to AAAA, batteries have become a vital part of our life. Active and Passive Components There are two types of Electronic components; Active and Passive. Active components supply more energy than they use, such as a battery. A Passive component absorbs or uses more energy than they supply, such as a light or a wire. ____________________ ____________________ Q 30-31 Label the diagrams above as Active or Passive. Current There are two types of current. Direct Current (DC) and Alternating Current (AC). Direct Current uses a continuous flow of electrons in the same direction, such as that produced by Batteries. Alternating Current (AC) is the second type of current which involves a periodic reversal in the direction of electron flow, such as that provided in the outlets in your house. ___________________ _______________ Q 32-33 Label the diagrams above as AC or DC current. Volts, Current and Resistance Q 34 Sketch the VIR Pyramid above. There are three basic units in electricity; Voltage (V), Current (I) and Resistance (R). Voltage is measure in Volts, Current is measured in Amps and Resistance is measured in Ohms. The basic formulae states that Voltage = Current x Resistance. Q35 V = ______________ Q36 I = _____________ Q37 R=______________ Example If the Current is (I) = 0.02 amps and the Resistance (R) = 250 Ohms, what is the Voltage (V)? Answer V = I x R = 0.02 x 250 = 5V Q 38 If the Voltage is 200 V and the Resistance is 75 Ohms, what is the Current? Answer ____________________ Q 39 If the Current (I) = 0.05 amps and the Voltage is 10V, what is the Resistance (R)? Answer ____________________ Electronic Posters and Circuits To construct an Electronic Poster you will require circuit components such as; wires, batteries and light bulbs. Circuits can be connected either in Parallel or in a Series. Parallel Circuits If two or more lights are connected like the rungs of a ladder then they are connected in parallel. In a Parallel Circuit each component receives the battery voltage. if one bulb burns out all the other bulbs will remain on. Q40 Re-sketch the Parallel Circuit. Q41 Redraw the Parallel LED Circuit above. Q42 Re-sketch the Series Circuits above. Series Circuit In a Series Circuit, all components (lights) are connected in a line. The voltage is divided among each component but the current stays the same. In a Series of Christmas lights, if one bulb burns out all the other bulbs will not turn on. Q43 Draw the Series LED Circuit above.
