Britt Gow . STEM specialist teacher. May 2017. What is STEM?. A = Flying a drone?. . B = Testing a ramp?. . C = Building a bridge?. . D = All of the above? . What is STEM?. The acronym stands for Science, Technology, Engineering and Mathematics, but it is more . Up to this point we have learned that static electricity can build up to a point where it results in the discharge of that energy in the form of a spark or lightning strike.. Next we will draw on your prior knowledge (gr. 6) to help learn about currents and circuits. . Essential Questions for Circuits. What are the requirements of a circuit?. What is actually going on in a working circuit?. What variable(s) affect what other variable(s) in a circuit? What law(s) and formulas govern the relationship(s) between these variables?. Electric Current - . Flow of electrons through a material. Electrical Potential – . Similar to potential energy . Remember PE is . llifting. something higher against the force of gravity gives it greater potential to do work, increasing its potential energy.). What we’re now learning:. Series Circuit. A . series circuit . has a single path for the current. Series Circuit. There is only one path for the electrons to flow. This means the . current must flow through all loads. Electromagnetic Force. The current in a circuit is driven by…. Generally, what . is needed for motion to take place?. Consider that electric current is the movement of electrons. what is the tension (pressure) on the current?. 9. th. grade. Electronics Introduction. What is Electricity. What does Electricity mean to you?. Where does it come from, how does it work?. Electricity. It is the many physical quantities and properties associated with electrical charges.. Activator. Essential Question:. How are series and parallel circuits similar and different in how they transfer energy. ?. Standard:. S8P5b. . Demonstrate the advantages and disadvantages of series and parallel circuits and how they transfer energy. Activator. Essential Question:.
