Env Science - Lesson 1
- 2. GROUND RULES • Raise your hand before you ask a question or respond to another students comment.
- 3. GROUND RULES • Be encouraging to your other classmates.
- 4. SAFETY RULES…YES MORE RULES • We will only work with circuits in the class with the materials provided • You are only allowed to work on circuit projects at home ONLY IF YOUR PARENTS ARE SUPERVISING • Do not go home and mess with outlets, batteries, or any other type of electrical device You can really really hurt yourself.
- 5. LET’S INTRODUCE OURSELVES TO EACH OTHER 1. What’s your name? 2. Why are you taking this class? 3. What do you do for fun?
- 6. WHAT DO I DO? • I am a PhD student at Rutger University - Newark • I do research into how conductive the ground is… I shoot laser beams into….just kidding • But I do shoot electromagnetic waves into the ground to better understand what’s under the ground
- 8. WHAT DO YOU ALREADY KNOW? • Let’s see what you have already done… 1. Paper Circuits 2. LED 3. Breadboards 4. Raspberry Pi 5. Switches 6. Using batteries 7. What else have you all worked with in regards to circuit design
- 9. WHAT DO YOU ALREADY KNOW? • Take out a sheet of paper and write down one thing that relates to circuit design that you already know!!!
- 10. WHAT WE WILL COVER IN THIS CLASS • The first few weeks will be discussing electromagnetism, electricity, circuit blueprints, how batteries work • Then, we will put all the theory to practical use • Maybe we can solve a problem and apply our knowledge to an environmental problem!!! • There will be quizzes…don’t worry
- 11. THE TAKE AWAY • I don’t want you to leave this class and only be able to light up LED lights • I want you to be able to apply what you have learned and use it!!!!
- 12. A LIL HISTORY Alessandra Volta • Invented the 1st battery • Aided scientists in producing steady flow of electric current • A unit of electric potential was named after him. (the Volt)
- 13. BEN FRANKLIN • Benny was the 1st person that we know of to discover electricity • Up until that time, scientists had mainly known about and experimented with static electricity. • Benjamin Franklin took things a big step ahead. • He came up with the idea that electricity had positive and negative elements and that electricity flowed between these elements. • He also believed that lightning was a form of this flowing electricity.
- 14. HOW DOES ELECTRICITY WORK • Electricity is the flow of electrons around a circuit. • But why do the electrons flow around a circuit? • Can a circuit be made of anything…like a piece of wood? • Metals like copper have what is know as free electrons • What the math is an electron?
- 15. WHAT ARE RESISTORS AND CONDUCTANCE
- 16. HOW DOES ELECTRICITY WORK • Take that same sheet of paper and write down something you learned from this lecture that you did not know before?
