Silver Plated Bulbs

I have used several different versions of the Silver Mirror or Tollen's Test lab. I am sharing the method that has proven to be the most reliable for me. The solutions should be made fresh, the directions must be followed closely and timing is very important. I like the fact that relatively small amounts of the chemicals are required, but as always you must be vigilant with safety precautions. 

Time required: 

15 minutes of prep time and 20 minutes of class time if you have multiple hoods available for students to use. I only have one hood, so I have another activity for students to complete while two groups rotate through the lab over two 60 minute class periods. 

Types of Chemical Reactions

I expect that most high school chemistry teachers assign some type of laboratory related to types of chemical reactions including synthesis, decomposition, single replacement and double replacement reactions. I have used several published versions, but I am sharing my modifications.

Time required: 

20 minutes prep, 40 minutes laboratory, 15-20 minutes discussion

Energizer Lab

Students proceed through a prior knowledge activity, practice creating and using a voltaic cell and use of a model designed to simulate the particulate level activity within a voltaic cell. The teacher checks for student understanding at specific points as groups work together. A discussion follows to help clarify ideas.

Time required: 

About one 60 minute class period for lab and manipulative procedure.

Trend Setter Lab

Students will proceed through a pre-lab engagement activity, organize element cards based on similarities & trends, discuss trends with the class and then produce a periodic table that includes the trends discussed within the lab. The teacher will check for student understanding at specific points as groups work together.

Time required: 

Two 60 minute class periods for procedure. You may wish to include more time for discussion. The assessment portion can be done as homework.

Periodic Table Project

Students choose a topic and select items to incorporate into a periodic talbe. Students explore trends related to their own topic and relate to the trends on the actual Periodic Table of Elements.

Time required: 

I provide my students 1 and 1/2 weeks to complete this project. Most students do not need this much time. I provide the extra time for those students who do not have adquate internet/computer access.
