For the ‘touch and feel’ part, the students can possibly visit an actual laboratory for a short duration. The lab report should include the actual data taken in the lab, not recopied versions. Compounds can be categorized as either ionic or molecular. The voltage on the electroscope is V = Q/C, and may be something like 50 pF, though of course this varies greatly with construction. This is a lab report that is based on couloumb's law. If a charged rod is brought near an electroscope, its leaves will diverge. Electric Charge experiment Part 1 – Introduction In this experiment, you have various types of rods available to you. A simple tool used to detect small electric charges known as an electroscope functions on the basis of conduction. In this section of the lab we used an electroscope, like the one in chapter 16 of our text, to observe electrostatic forces. Thank you. 2. This week, we are doing a static electricity experiment. By studying the terminal velocity of coffee filters with different masses, Enjoy fun science experiments for kids that feature awesome hands-on projects and activities that help bring the exciting world of science to life. conducting pith ball on stand. Pendulum Lab. Slinky Lab. It is a device that is used for detecting whether an object is charged or uncharged. The basic construction consists of an earthed metal box with glass windows, as shown in Figure 3. Touch a charged rubber rod to the top of an electroscope again. LABORATORY III ELECTRIC ENERGY AND CAPACITORS Lab III - 1 Our modern society functions in part because we have learned how to manipulate electrical energy. The battery was 9 volts and is the power supply in the lab. Electrostatic Induction and the Faraday Ice Pail Adapted from 8. An electrostatic generator, or electrostatic machine, is an electromechanical generator that produces static electricity, or electricity at high voltage and low continuous current. Good Lab Report. The Speed of Sound Lab rubbing and when we placed it near the electroscope it made the An electroscope is a scientific instrument used to detect the presence and magnitude of electric charge on a body. Different materials were rubbed on many rods to determine the charge that was produced. Electrostatics* Objectives: This work concerns electric charge, electric forces, flow of charge in response to electric fields, use of an electroscope and charging by induction. How to do the photoelectric effect experiment. The electroscope vane moves away from the support. Electrons are said to carry negative charge, while protons are said to carry positive charge, although these labels are Practice Problems: Coulomb's Law Click here to see the solutions. Description. Box 519 - Prairie View, Texas 77446 This electroscope is great for hands on experience with electrostatic principles in physics classrooms and labs. favorite post this week is from Marci at The Homeschool Scientist who shares with us the steps to Make An Electroscope to Experiment When the electroscope detects static electricity, the foil ball pushes out from the pan. Physics 133 Electroscope • Predict what will happen if a charged rod is brought near an electroscope with an insulator below the top ball. That is, a positive rod will induce the electrons in the scope to migrate to the knob. The questionnaire must be completed and handed in to your Lab TF’s mailbox before 6 PM on February 20.
