►We can conclude that:
- Some materials are attracted to the magnet (magnetic materials)
- Other materials are not attracted to the magnet (non-magnetic materials)
• Floating and sinking of substances don't depend on their masses.
► What happen to the mass of object if its shape changes?
-The mass will not change (still constant)
► Mass is affected by increasing or decreasing the amount of matter.
