1. Fun With Color and Liquid!

2. Sparkling Water

3. Canola Oil

4. Hydrogen Peroxide

5. White Vinegar

6. Apple Cider Vinegar

7. Blue Agave

8.  The teacher will introduce the activity by having a class- wide discussion about density, viscosity, and food coloring. Has anybody experimented with food coloring before? What do you do after the initial drop to make the coloring spread evenly? What makes a liquid sticky? How does the speed at which a liquid leaves the bottle effect how food coloring will spread when dropped in it? 5 E Model - Engage

9.  Now it’s time to explore!  Allow students to freely explore the materials in front of them. Encourage them to try different combinations of coloring and liquids to see how results might vary.  Possibly mix liquids of different viscosities together to see how it might change things. 5 E Model - Explore

10.  In their science notebooks, students will answer questions about the experiment:  How did the liquids react to the addition of food coloring?  How does the speed at which the liquid comes out of its original container indicate how the food coloring will dissipate?  Categorize the liquids by their viscosity. 5 E Model - Explain

11.  How can the liquids be altered to make the food coloring dissipate faster?  Students will heat and cool the liquids to discover how this effects results.  Any other ideas on how to alter the materials can be explored and explained in the students notebooks. 5 E Model - Elaborate

12.  The teacher can evaluate the students’ understanding by taking a look at their science notebooks. As long as the student displays their findings in a clear and organized way, their evaluation should reflect their effort.  Students with limited English proficiency can describe their findings in any way that works best for them; whether it be drawings or short statements. 5 E Model - Evaluate
