Question:

Does water hold together well or come apart easily?

Learning Tasks:

  1. Do Now– Copy down your homework assignment in your planner. Get out your science notebook and add to the Table of Contents- “Water Investigation-p.38” (Left Side). Head page 38 properly with “Water Investigation-1/9/18.”
  2. Scientists’ Circle- Bring your ISN and share observations. When you squeezed the drop of water out of the dropper, did the water break apart or did it hold together? When you tilted the wax paper, did the drop split apart or stay together? When you were pulling the drop around the wax paper, did the water seem to hold together or come apart easily? When you tried to split your drop, did the drop separate easily? What happened when the two small drops touched?
  3. Demonstration Food coloring in water- What do you observe? What does this tell you about the particles that make up water?
  4. Model– On ISN page 38, draw a model of water on molecular level based on your observations of the investigation and the demonstration. Make a claim about whether water holds together well or comes apart easily. Support your claim with evidence and reasoning. Observe animation of liquid water molecules and adjust model.
