Experiment One: Laboratory Techniques and Measurements Objectives: 1. To apply basic knowledge regarding the measurement of mass‚ length‚ volume‚ temperature‚ and density 2. Learning to identify and use tools provided within the labpaq kit 3. Becoming familiar with common lab tools used in Chemistry Observations: While participating in experiment 1‚ I was able to become familiar with my new lab kit. I observed how to weigh and measure objects as well as record those findings in an organized

dichotomous keys for classification. Procedure: To start the experiment with exercise 1‚ I gathered all of the needed supplies‚ both from around my house and from the lab paq CD. I then began exercise one by printing the images in Figure 5 from my labpaq. I then proceeded to cut out each shark. Next I carefully examined the drawing of shark specimen 1. After examining the shark I went to the Key to the Classification of Sharks by Family chart. There‚ I went through each question‚ answering yes or

Purpose The purpose of this lab experiment is to observe physical and chemical properties of substances which are also known as chemicals. Procedure For this laboratory experiment I followed the detailed procedures outline in the Labpaq manual by P. Jeschofnig‚ LP-0125-CK-01. (Jeschofnig‚ Peter.‚ Ph.D.‚ "Physical and Chemical Properties." General College Chemistry. Englewood‚ CO: Hands on Lab Inc.‚ 0. 65-71. Print.) First‚ I followed all safety measures as outlined therein. After

-Meniscus is a measurement used for measuring liquids‚ for water and most liquids the line with the center of the meniscus reading in the bottom is used. 6. How would you clean the lab after completion? - Items in labpaq are generally used multiple times. Always clean and return un used items to the bag after completing experiment. -Clean used and left over chemicals with paper and place in a garbage or flush down using enough amount of water

let us know the vinegar have reach a point of neutralization once the vinegar turns pink. We can then calculate the concentration of acetic acid in the vinegar. Procedure: Data: Set up the lab: Take a tick text book and place it on top of the labpaq box to use as a titrator holder. Slip the clamp into the textbook by placing the test tube clamp into the middle of the book. The stop cock tip should be 1-2 cm above the beaker. Use the test tube holder to clamp the 10 mL syringe with an affixed

arrangements using several magnification techniques by way of 10x‚ 40x‚100x oil immersion lenses and a light source. The main purpose was to observe the shapes and arrangements of microbial bacteria and yogurt. Procedure The lab involved self-provided and labpaq materials to perform several exercises to obtain the purpose of the lab. The lab began with the proper identification of all components of the microscope and their functions. This allowed for preparation of the objective of being able to view specimens

Identification of Metallic Ions TITLE: LAB 5.1 IDENTIFICATION OF METALLIC IONS PURPOSE: In this lab we are learning how to observe and perform “flame tests”‚ of alkali and alkaline earth metal ions. We will use basic lab equipment provided in our Labpaq‚ and follow all safety precautions in this lab. From reading the discussion and review‚ we understand that the normal configuration of the electrons is called “the ground state”. We understand that they are in stable condition‚ while at their lowest
