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.

Test #1: Gravel

Q: Who’s in charge?

• 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.
