Demonstrate that things can be done to materials to change their physical properties such as cutting, folding, sanding, and melting.
The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.
Chemical vs. Physical Changes: CHEM4KIDS (website) - Physical changes do not change a substance’s chemical makeup. Learn how to distinguish physical and chemical changes.
Melting and Freezing: Science NetLinks (website) - Students explore how melting and freezing impact everyday items as they change form a solid to a liquid or a liquid to a solid.
Materials and Manufacturing: Science NetLinks (website) - Students examine the properties, limitations and durability of various materials, and evaluate which materials would be best for building a model house.
