EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

Materials/Methods For unit 7.3 the experiment needed 2 microfuge tubes one labeled "L" for lactose and the other labeled "M" for maltose. The experiment also called for a total of 3 clean plastic pipettes. With one pipette add milk up to the 0.5 line of the lactose tube. With the second clean pipette add maltose solution up to the 0.5 line of the maltose tube. With the third
