Changes in Matter - Looking for Details
The states of solid, liquid and gas are not the only physical properties of matter.
Physical properties include any observations that you can make about a substance using your five senses.
Pretend you are observing a spoonful of salt.
What do you notice?
Salt is solid, hard, white, and made of small grains. All of these observations, including the taste are physical properties. If you look very closely or use a magnifying glass, you will notice that salt grains are small square boxes. These are all physical properties of salt.
- With a partner, play a guessing game using physical properties. Think of an object. Describe the object’s physical properties one at a time. Remember to use the five senses in your descriptions. Your partner should try to guess what the object is using as few clues as possible.
- Some countries do not have root beer. Write a description of the physical properties of root beer for someone who has never tasted it. Include all of the five senses in your descriptions.
