Consider FIVE types of solids:
Ionic (NaCl)
Metallic (Ca)
Covalent Network (Quartz, SiO2)
Polar Molecular (sugar, C6H12O6)
Non-polar molecule

RECALL THE PHYSICAL PROPERTIES -> hardness, brittleness, the conductivity of electricity and heat, melting and boiling points, solubility in water, etc.

1. Design an experimental procedure to test these properties with the procedures below.
-> the ones I have so far
- ionic solids -> use NaCl and dissolve in water to test the solubility
- conductivity - by putting the solid under two free ends of the wire
-> solubility - using boiling water for all as ionic solids break into ions & conduct electricity
- brittleness - using a hammer or any other form of stress (if brittle, tends to break under stress)
- hardness - using a hydraulic press/Rockwell testing
- melting/boiling point - add heat to a sample after placing in a beaker or test tube to test

SOME OTHER THINGS WE CAN USE (but I'm unsure as to what we can use it for): a thermal camera

2. WRITE A HYPOTHESIS for ONE TYPE of solid with a brief explanation.
-> I'm having some trouble with where to start for this?

3. Design a Table of Observations for your experiments.
-> I'm unsure as to how to do this??

You actually don't need boiling water for the test.

- hardness - using a hydraulic press/Rockwell testing

Even just trying to scratch with a knife will give some info.

Not sure what for. Heat conductivity to some extent perhaps.

It can be really anything, like "harder solids have higher density". Doesn't matter if it is true, you are about to test it to either prove, or disprove.
