Below are some of the differences between the properties of metals and non-metals

You are going to test three different elements and determine if they are metals, non-metals, or metalloids. You have the following things to use.
  1. Your own eyes and hands
  2. A small hammer you can use to try and break the element
  3. A conductivity meter

Use your answers to the questions above to fill in the blanks of your Evidence.

In this lab we tested three samples. Sample #1 looks_________ . Sample #2 looks__________ . Sample #3 looks__________ . When we hit each sample with a wooden hammer, sample #1 ________________ , sample #2 ___________________ , and sample #3 ________________ . We tested each sample with a conductivity meter. To use the conductivity meter you must turn the switch on and hold each copper electrode to the sample and make sure the two electrodes are not touching each other. When tested sample #1 lit ______________ . When tested sample #2 lit______________________________________ . When tested sample #3 lit__________________ .
Other Answer Choices:

Use your Evidence and the information from the graphics at the bottom of the page to fill in the blanks for the first part of your Reasoning.

The appearance of metals is______________ or shiny. The appearance of non-metals is _________ or not shiny. Sample #1 appears_________ . Sample #2 appears ______________. Sample #3 appears ______________ .

When you hit a metal with a hammer you expect it to____________ , because metals are ______________ . When you hit non-metal with a hammer you expect it to __________ , because non-metals are ____________ . When we hit sample #1 with the hammer, it did__________ , which makes it____________ . When we hit sample #2 with the hammer, it did_______________ , which makes it______________ . When we hit sample #3 with the hammer it did__________ , which makes it____________ .
Other Answer Choices:
not change
lusturous
flatten
brittle
break
malleable
dull

Use your Evidence and the information from the graphics at the bottom of the page to fill in the blanks for the second part of your Reasoning.

When the the lights on the conductivity meter light up it indicates that the material being tested has _________ conductivity. Metals have _________ conductivity, so you would expect the conductivity meter to _____________ when testing a metal. Non-metals have________ conductivity, so you would expect the conductivity meter to_____________ when testing a non-metal. When sample #1 was tested with the conductivity meter______________ lit up, which means it has________ conductivity. When sample #2 was tested with the conductivity meter_________________________________ lit up, which means it has_________ conductivity. When sample #3 was tested with the conductivity meter_______________________ lit up, which means it has_________ conductivity.
Other Answer Choices:
dull
just the red light
lusturous
both the red and green light
good
light up
not light up
bad
no lights

Use your Evidence and the information from the graphics at the bottom of the page to fill in the blanks for the last part of your Reasoning.

Since Sample #1 appears_________, is ____________ when you hit it with a hammer, and has ________ conductivity, it has the characteristics of a __________ . Since Sample #2 appears______________ , is ______________ when you hit it with a hammer, and has _________ conductivity, it has the characteristics of a __________ . Since Sample #3 appears______________ , is____________ when you hit it with a hammer, and has________ conductivity, it has the characteristics of ______________ .
