The Electron Charge to Mass Ration Lab Report
The purpose of this lab is to recreate a modified version of the experiment that J. J.
Thomson used to discover the electron. The important characteristics of the electr
Physics Lab Report 5 The Electron Charge-To-Mass Ratio Teddy Portney 4/10/07 Lab LK Section A I. Introduction After J.J. Thomson, a British physicist, discovered the electron in 1897, he conducted many experiments over several years. Through these ex
The Electric Field and Electric Potential Lab Report
In this lab, we applied our study of electric fields and electric potential to investigate the
relationship between electric field and electric potential. Th
Physics Lab Report 1 Simple Harmonic Motion Teddy Portney 1/30/07 Lab LK Section A
I. Introduction Simple harmonic motion is a type of oscillation, which is undampened and undriven. It is periodic, represented by equations for displacement, velocity

Standing Waves Lab Report
In this lab, we applied our studies of simple harmonic motion, oscillations, and harmonics
to look at standing waves. Standing waves have a specific frequency that creates a
Physics Lab Report 2 Standing Waves Teddy Portney 2/12/07 Lab LK Section A I. Introduction Standing waves occur in a fixed object with some distinct length. Standing waves are essential to the way music is made. In most non-synthesized stringed instr
Electrical Circuits and Electrical Resistance Lab Report
In this lab, we experimented with the properties of electrical resistance in electrical
circuits. A resistor creates resistance within a circuit by transformi

Magnetic Induction Lab Report
In this lab, we looked at the relationship between the current in a loop of wire and the
magnetic field it produces. Also, we examined the change in voltage due to a change in magn
Chapter 8: Chemical Reactions in Solution
How can you tell that a chemical reaction has taken place?
1. formation of a solid precipitate
2. formation of water
3. formation of a gas
4. transfer of electrons
Molecular Equation: BaCl2 (aq) + Na2SO4 (
Chapter 10: Energy
Change of energy = m x g x h
Potential energy remains constant.
Energy capacity to do work
Heat describers transfer of random motion to one another. movement of energy from
one place to another; goes from high to low by collisio
Chapter 12: Chemical Bonding
What is a chemical bond? bond = force that holds groups of two or more atoms together
and makes them function as a unit.
Electrostatic forces hold atoms together.
Ionic Compound- Ionic substances are formed when an atom that l
Chapter 3: Chemical Foundations
Ionic compounds always start with a metal. Al_
Ionic compounds always have very uniform structures (regular arrangements) because
electrostatic forces have to balance (in terms of distance).
Covalent Bonds: Molecule
Chapter 2: Matter
\Compounds = fixed ratio of atoms
Ionic compounds vs. Molecular compounds
Types of Mixtures
- IMPORTANT: In water, if a substance appears cloudy it is because light is being scattered differently.
