1. 6.- CONSOLIDATION AND EXTENDING ACTIVITY. Split yourselves into groups
of two or three people. Try to put the strips into a sensible order.
Solids have a fixed shape and size.
Most solids are crystalline, where the molecules are tightly bound to each other, and
are arranged in specific repeating patterns.
Liquid- The bonds between the molecules in the solid break when it melts. When
heating a solid, its molecules speed up and the increasing vibration eventually breaks
the bonds. Molecules in liquids are touching but can move around.
Solid- Molecules packed so tightly together that they cannot move
anywhere- still vibrate with energy though.
The bubbles in boiling water are bubbles of steam that form at the bottom and rise
to the surface.
Gases can change shape and size. In gases, the molecules are not
connected to each other and can move around freely
However, water and ice are unusual because ice takes up more room than water. This
makes it less dense than water, so it floats
Gas- molecules have lots of space to move around but bump into each other a lot
because they move so fast.
