Radio Control Setup
In this section, you will learn the Radio Control subsystem components and make sure
the system is ready for use.
The VEX Radio Control Transmitter is your primary means of human control over the robot
In this lesson, you will learn how to set up a sensor in ROBOTC.
The standard SquareArm design has some weaknesses which can be difficult for a human
operator to work around. One of the worst is that the arm can
In this lesson, you will learn how the buttons on the back of the Vex Transmitter can be
used to send values to the robot.
You already know how the joysticks on the front of the Transmitter work. Lets take a look a

Motor Power Levels
In this lesson, you will modify the existing program to change the motor power level.
This helps you to move your robot more consistently and precisely.
Moving at slower speeds can help your robot to
Programming in ROBOTC
In this lesson, you will learn the basic rules for writing ROBOTC programs.
ROBOTC is a text-based programming language
Commands to the robot are first written as text on the screen. They are then pro
Time and Timers
In this lesson, you will learn how Timers differ from simple wait1Msec commands,
and how ROBOTC handles them.
The rules for the game state that you have only two minutes from the starting signal to control
your robot, a
In this lesson, you will modify the existing sample program code to create a new behavior for
your robot: Moving Forward. Be prepared for the robot to do what you told it to do, not what
you expected it to do!

Evidence from Ionization Energies
Ionization energy is the energy required to remove an electron from
an atom (or ion) in the gas phase, typically measured in kJ/mol.
As atom radii decrease, the attraction between the nuclei and the

Guidelines: Lab Report
Students require a lab book for formal lab reports. Lab books are not binders in which papers
are added/removed, nor do lab books have metal ring bindings. For simplicity, Hilroy

Solution and Molecular Polarity
In the formation of a solution, a solute dissolves in a solvent. Whether or not this process occurs depends
both on the forces of attraction between the solute and solvent, and also on the intern

The shape, orientation and size of the bonding orbitals used by each atom in a molecule will
determine the overall shape of the molecule.
Group Discussion Questions: Atomic Theory
All groups should work on every question. Start with question one and then follow the order given by your
teacher. Questions will be discussed in the last 15 minutes of class time.

Amines are considered to be derivatives of ammonia, NH3.
As displayed in the images below, primary amines arise when one of three hydrogen atoms in ammonia
is replaced by an organic substituent. Secondary amines have two organic substituents bound
