Today we finished off the the MC Hammer/MJ lab. We took a few minutes to review how to use the periodic table that we took notes on. We then had a simple demonstration about one of the physical traits of metalloids. Some metalloids are semiconductors which mean that they can conduct electricity at high temperatures and do not conduct electricity at low temperatures.
Here is a video on how silicon is a semiconductor.
We then took a few minutes to look at how density is an important physical trait in elements.
Here is a video about density.
Keep in mind we have a test on Friday and students need to study the material for chapter 10 of the textbook for test. I do have a Test help section on my website.
