Lab 6:  Electromagnetic Spectrum

 

 For this lab you will go to the following web page: http://www.glencoe.com/sites/common_assets/science/virtual_labs/CT05/CT05.html

 You may want to print this page for a reference.

When this page opens please read the introduction, objectives and procedures found at the left side of the web page in the scroll down menu.  It is very important that you follow the directions found in the procedure section for this interactive lab to work. Once you complete items 1-7 under the procedure directions (see web page) you can complete the journal questions (number 8).   These questions are listed on the answer sheet below for this lab.  You do not have to enter your answers to the journal questions on the web page, but you must enter your answers on the answer sheet and then post in the Dropbox. The answer sheet is located below. You may want to cut and paste the answer sheet into a word document then type your answers to the questions.  Once you have answered all the questions listed on the answer sheet and you have input your data into the table on the answer sheet (see number 4 on the procedure)  just cut and paste your answer sheet into the Dropbox.  You may also post the answers as an attachment if you wish.
