Lesson Objectives

  • Students will be able to explain that mixtures are a combination of two or more materials that retain their own properties. They will also be able to identify mixtures.

  • Students will be able to explain that a solution occurs when something is dissolved in a solvent and the two cannot be separated with a filter. They will also be able to identify solutions.


Lesson objectives

Test #1: Gravel

Q: Who’s in charge?

A: The Gravel Genius!

  • Step 1:CAREFULLY measure 50mL of water using the syringe.

  • Step 2: Slowly squirt the water into the cup containing gravel (marked “G”)

  • Step 3: Use the popsicle stick to stir the contents of the cup.

  • Step 4: Write down your observations of what you see in the cup.

  • Step 5: After the water and solid are evenly dispersed, the group leader will pour the contents of the cup through a screen and into an empty plastic cup marked “G”

  • Did the solid separate from the water using the screen?

  • YES: there is no further testing required for that material.

  • NO: Use the filter and funnel to try and separate the two.

  • While the designated group member is taking their turn creating and separating the mixtures, the other two group members will record their observations on the student lab worksheet.

Test #3: Salt

Q: Who’s in charge?

A: The Salt Specialist!

  • Step 1:CAREFULLY measure 50mL of water using the syringe.

  • Step 3: Use the popsicle stick to stir the contents of the cup.

  • Step 4: Write down your observations of what you see in the cup.

  • Step 5: After the water and solid are evenly dispersed, the group leader will pour the contents of the cup through a screen and into an empty plastic cup marked “S”

  • Did the solid separate from the water using the screen?

  • YES: there is no further testing required for that material.

  • NO: Use the filter and funnel to try and separate the two.
