Properties of Matter

A 4th grade class of students are measuring 3 small objects and are instructed to place them in a beaker of water. One of the object sinks, another object floats in the middle, and the last object also floats.  

Which conclusion best describes what the students observed? 

• All three objects are different sizes.

• One object is more dense than the other two.

• The objects are dissolving in the water. 

• Each object is made of a different type of material.

What is Solubility?

• Is the ability to dissolve in liquid.

• Is the amount of space something takes up.​

• The amount of matter in an object.

• Physical properties that can be observed or measured.

What is ​Volume?

• A force of attraction or repulsion.

• Is the amount of space something takes up.​

• The amount of matter in an object.

• A solid, liquid or a gas.

What is a mixture?

• The amount of matter in a object.

• A combination of 2 or more substances that keep their physical properties and can be easily separated. ​

• A combination of 2 or more substances that do not keep their physical properties and can not be easily separated. ​

• The amount of space an object takes up.

Which of the following is a mixture but not a solution?

• Hot tea

• Orange juice

• Fruit salad

• Chocolate milk

Solution is a type of mixture in which the particles of one or more substance dissolves and are not easily separated. One way that solutions are different from mixtures are —

• Solutions have higher temperatures than other mixtures.

• Solutions are a mixture of only two substances while other mixtures can mix 3 or more substances.  

• Solutions have more mass than mixtures. 

• Solutions are not easily separated, while other mixtures are easily separated.
