Mixtures Day 3

I can explore and recognize that a mixture is created when two materials are combined

Key Concepts

• Mixtures are formed when two or more materials are combined.
• The observable properties of materials may stay the same even when materials are mixed together
• Mixtures can be separated based on the properties of the individual materials.

Fundamental Questions

1. What is a mixture?
2. What happens to the observable properties of various materials when they are mixed together?
3. How can the materials in a mixture be separated?

Station 3: Separate the Mixture

1. Students will use materials on their table to explore and recognize that a solid/solid mixture is being made.
2. Students will then use the materials on the tools table to see if they can easily separate the mixture.
3. In this scenario, students should use the magnets to easily separate the mixture; However, they may try a variety of methods and discuss what properties they are separating them by.

Station 3 Instructions:

Observe the materials at your table. Is it a mixture? Why or why not?

Can you easily separate the material by their physical properties? 

Use the tools to test and separate the material.

Mixtures can be easily separated by their physical properties. What would be a really fast way to separate this mixture?

Write 5 ways to separate the mixture (you do not need to separate the mixture all five ways):

What physical property allows you to separate the mixture fastest?

Some substances were magnetic. What physical property was used to separate them?
