Transcript: You should be wondering what's the meaning of "washer" and "fluorescent starter" we'll cover them in the next slide Step 1 : Soak the three pieces of cardboard (which you have trimmed into a circle - should be about the size of the zinc washer) into saltwater with a ratio of about 1 tablespoon of salt to 100ml of tap water. Step 2: Put the following items in these order: Zinc at the bottom, cardboard in the middle, and the 1-cent coin on top. Step 3: Nope, no step 3 :D You're done! Now let's test the voltage Time to test the calculator :D This is a voltaic pile :D It's the ancient origin of batteries. How they first came about. Challenges Well, you might not have heard of them, but that's not important. We're going to show you. What is a voltaic pile. 1 Cell Time for some in-depth explanation In case you guys think it s fake :P The calculator couldn't work well and automatically turned off itself after 5-30 seconds of use. and thats some suspense over there* Definitions from google: ' Used masking tape to wrap up the voltaic pile. Found that it was not working well because the electrolyte dried up really fast due to the masking tape sucking the water up. YAY!!!! Wait...... Bought a random cheap China calculator and opened it up. So this is a little improvisation :D You're done! Now let's test the voltage :D Lets move on to how we did it :D Used masking tape to wrap up the voltaic pile. Found that it was not working well because the electrolyte dried up really fast due to the masking tape sucking the water up. THAT DOESNT MAKE SENSE, WE HAVE ALREADY SUCCEEDED :D Introduction ~ MOVING ON ~ Calculators, Torchlights, Diodes, etc :D Also, I used 4 cells for this So... Prior to this, I actually made a voltaic pile of 3 cells and tried to power my calculator Also, the wires' contacts were not well stuck together. Also, the wires' contacts were not well stuck together. << End result Also, the wires' contacts were not well stuck together. Snipped the speaker wires off Step 2: Drill a hole into the other end of the starter. Prior to this, I actually made a voltaic pile of 3 cells and tried to power my calculator Physical Sciences Presentation Topic Chosen: Innovative ways to consume less energy at home Explanations on its theory Wire B The calculator couldn't work well and automatically turned off itself after 5-30 seconds of use. What are we doing? And some wires Basically almost anything that requires 1.5V to work. (3 cells produce about 1.5V to 2V) However, as there are not enough amperes, more cells are encouraged. I used 4 cells for this - the more the merrier, as long as you have the materials! Group Members: Ashraf Roshan Premakumar Ganesh Uses 3 pieces of cardboard /mounting board / paper towels Fluorescent starter: A device with a voltage-sensitive switch and a capacitor that provides a high-voltage pulse to start a fluorescent lamp Wire A DID YOU REALLY THINK THAT WAS ALL? WE STILL HAVE A VIDEO !!! . Success Challenges we faced. That was when I stumbled upon my awesome fluorescent starter and I decided to reuse it by removing the switch and the capacitor inside my starter. And VOILA! I have my voltaic pile holder :D Also, the wires' contacts were not well stuck together. Group Leader: Chan Jun Yi Extended the wires longer so that I can easily access the positive and negative ends from the outside. Acknowledgements Washer: A flat ring or perforated piece of leather, rubber, metal, etc., used to give tightness to a joint, to prevent leakage, to distribute pressure, etc. So, here are the steps to making a voltaic cell. The voltaic pile was the first electrical battery that could continuously provide an electrical current to a circuit. Recycled materials we used to make a voltaic cell . Step 1: Using masking/electrical tape, tape one end of wire A to the 1-cent coin, and wire B to the zinc washer. Used masking tape to wrap up the voltaic pile. Found that it was not working well because the electrolyte dried up really fast due to the masking tape sucking the water up. Working just fine ! :D Homemade batteries :D ~ Using the concept of voltaic piles :) A challenging project :P 1 recycled fluorescent starter Used masking tape to wrap up the voltaic pile. Found that it was not working well because the electrolyte dried up really fast due to the masking tape sucking the water up. Final product should be something like... Also, the wires' contacts were not well stuck together. Three 1-cent coins I found dated after 1987 *cos they're copper-plated on the outside Finally the time to really test it out. Ooops, I forgot to tell you what the wires were for! 3 recycled zinc washers I found at home Used masking tape to wrap up the voltaic pile. Found that it was not working well because the electrolyte dried up really fast due to the masking tape sucking the water up. Step 3: Slot one end of Wire A through the starter and repeat the same for wire B Zinc washer Cardboard 1-cent coin Zinc washer Cardboard 1-cent coin Zinc Wire

Physical Sciences

Transcript: Balanced forces occur due to equal forces acting upon an object, therefore it doesn’t move. E.g a glass on a table. Unbalanced forces occur due to unequal forces acting upon an object, such as a round ball on a table. Science as a human endeavour: Scientific knowledge changes as new evidence becomes available and some scientific discoveries have significantly changed people’s understandings of the world Types of force continued... Thank you for Listening! Any Questions? To put it simply... Humans are constantly seeking to increase their understanding and explanations of the natural world. Gravity and Force = day-to-day life Job Opportunities - Manual labor, Engineering, Science exploration etc! Elaborations: Explain and predict phenomena Apply prior knowledge to new situations Practical experiments (E.g what can a force do?) Exploration, investigation, creativity Force How can this be incorporated? • Gravitational force is an attraction between masses. • The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). • The gravitational force weakens rapidly with increasing distance between masses. Gravity keeping planets in orbit Balanced and Unbalanced forces Elaboration: Investigating common situations where forces are balanced, such as stationary objects, and unbalanced, such as falling objects. Science Understanding Science Inquiry Science as a Human Endeavour Types of force What about gravity? Main Concepts - Thrust - Lift -Gravity -Drag -Push -Pull Elaboration: Considering how gravity keeps planets in orbit around the sun. Understand the importance of the sun for all other planets to remain in orbit How might a pulley system be useful when lifting heavy equipment? System consisting of two pulleys with a rope running around them to lift a load. Using two or more pulleys reduces the amount of effort needed. Forces in action The sun is our nearest star. The Sun is a big ball of gas held together by gravity. It is prevented from collapsing by the enormous pressure and temperature at its centre. The gravity of the sun holds all the other planets in its grip. Elaboration: Investigating a simple machine such as lever or pulley system. A pulley is a wheel that changes the direction of the force applied with a rope or cable. These have been used in factory type settings throughout history. Science as a Human Endeavour 7 general capabilities... 1. Change to an objects motion is caused by unbalanced forces acting on the object 2. Earths gravity pulls objects towards the centre of the Earth Elaboration: Investigating the effects of applying different forces to familiar objects Definition of Force: 2. Strength or power exerted upon an object; physical coercion; violence: to use force to open the window; to use force on a person. Elaboration: Exploring how gravity affects objects on the surface of the Earth What happens to your body when you are a passenger in a car and it goes around the corner? Science Strands Science Understanding Pulleys Lever or Pulley Systems Physical Sciences Year 7 - AUSVELS Balanced and Unbalanced forces Role Play. E.g. What would it look like with a pram if you couldn't Push? Gravity All planets orbit around the sun - not the other way around!
