Today we finished off the Density lab. We then glued in the Matter Flow Chart (top -->} ) on page 30, the Mass v. Density lab ( { <-- top ) on page 31, the Density lab on pp. 32 (X) and 33 (X). Again, we have a test scheduled for Tuesday December 15, 2020. The Science Test Help tab for this is up and ready for use.
We then move on to discussing more of the physical properties of matter we looked at the size dependent properties:
- Mass - How much matter is present
- Volume - How much space matter takes up
We then looked at the 6 size independent properties:
- Melting point Solid --> liquid
- Boing point Liquid --> gas
- Density How much matter in a given space
- Conductivity Transfer of energy both electricity (transfer of electrons) and heat
- Solubility Can dissolve one substance into another substance (See chocolate milk)
- Magnetism Force that attracts or repels certain metals especially iron
