When you add salt to water and the two substances combined taste salty, the particles are:

• Separated

• Equally Dispersed

• Molecules

• Oily

Oil and water have to be shaken to mix because:

• Oil is LESS dense than water

• oil and water make a solution

• Oil and water do NOT make a solution

• Oil and water do not distribute particles equally when mixed

Joanna put salt, sugar, water, and rocks in a cup. Then she shook the cup. When she finished, Joanna could see the rocks and water but not the sugar or salt. Which statement about the materials in the cup is true?

• The rocks made a solution with the water

• The sugar and salt equally distributed particles in water when mixed but the rocks sink to the bottom of the cup because they are more dense.

• The sugar and salt is no longer in the water

• Joanna spilled all the materials

Why is a solution a special kind of mixture?

• Because it is easily separated

• Because it equally distributes particles amongst each other

• Because it tastes delicious

What are the 3 things that help us determine if a combination of matter is a mixture:

• It can be EASILY separated

• It contains ONLY one substance

• It contains 2 or more substances

• The substances experience a Physical Change

What is a force that attracts or repels objects that are made of magnetic materials?

• Gravity

• Friction

• Mass

• Magnetism
