States of Matter Slime

1. Eureka! States of Matter: Liquids

Introduction Slime is a substance that has some properties of a solid, and some properties of a liquid. These types of substances are called colloids. Popular colloids include milk, mayonnaise, Jello, and even whipped cream. There are many different types of slime and many different recipes. They also have different names. To make Oobleck, mix water and cornstarch together. We will be making Glurch, or Flubber, which is made with Borax, glue and water-and I call Slime

Materials 40 mL water 20 mL white glue 2 drops food coloring 15 mL Borax (white powder) Small baggie 100 mL beaker 50 mL graduated cylinders 25 mL graduated cylinders

Before you start Be sure that you only put the glue in the beaker that says “glue” AND the water in the graduated cylinder that says “water” It’s important that the graduated cylinder for the borax stays completely dry. (DO NOT WASH OUT AT THE END OF THIS LAB!) Look over all the lab materials/equipment to be sure you know what materials can go into what equipment

Procedure: part 1 1. Clean all materials thoroughly. 2. Measure 20mL glue in a 100 mL beaker. 3. Measure 20mL water in a 50 mL graduated cylinder. 4. Add the water to the glue and mix with a stir rod. 5. Add both to a small baggie. 6. Get 2 drops of food coloring from Mrs G. 7. Seal bag (double check, make sure it is closed).

Procedure: part 1 8. Gently knead bag until thoroughly mixed. - Record observations in row 1 of your data table.

Procedure: part 2 9. Measure 20 mL water in a graduated cylinder pour into the CLEAN 100ml beaker 10. Measure 15 mL borax (white powder) into a 25 ml graduated cylinder (use scoopula). 11. Add the borax to the water and stir until mostly combined. 12. Immediately, add both to the baggie and seal completely.

Procedure: part Mix until there is no liquid - be careful not to break the bag! - Record observations in row 2 of your data table.

Procedure: part 3 WHEN YOU HAVE MADE YOUR SLIME…. 14. CLEAN UP EVERYTHING!!!! When you are done cleaning your desk/station – raise your hand to get a stamp
