2.
Plan and carry out investigations to gather evidence to support an explanation on how heating or cooling can cause a phase change in matter.2.P1U1.2
3.
Obtain, evaluate and communicate information about ways heat energy can cause change in objects or materials.2.P4U1.3

4.
Observe and investigate how wind and water change the shape of the land resulting in a variety of landforms.2.E1U1.4
