  Not at all A Little Mostly Very
Solid materials can be dispersed in the colloidal suspension if their sizes are very small, in the order of ten nanometers.
Surfactants are dispersion agents for objects in liquid that work by adhering to objects and creating a new repulsion between them, raising the energy required for objects to aggregate, and stabilizing the colloid.
Nanometer materials can be synthesized in solution, starting with their atomic ion forms, by controlled oxidation and reduction reactions.
Physics: Magnetic materials are sources of magnetic fields and are subject to forces arising from the magnetic fields of other sources
Physics: Magnetic fields contain energy and act as vector force fields
Chemistry: Describe the dissolving process at the molecular level using the concept of random molecular motion, and define solute and solvent.
Chemistry: Calculate the concentration of a solute in terms of grams per liter, molarity, parts per million and percent composition
Scientific Investigation and Experimentation: Identify possible reasons for inconsistent results, such as sources of error or uncontrolled conditions.

Were there sufficient materials in our supply kit for you to complete this lab with all of your students?
Did the hands-on activity during the Saturday workshop help you successfully conduct the experiment with your students?
Did the UCLA researchers’ presentations and your interaction with them during the workshop help you explain the science and answer all questions asked by your students?
Did the discussions amongst your science teacher colleagues, led by the Teacher Instructor during the Saturday workshop, help make it practical to integrate this experiment into your curriculum and bring the hands-on activity into your classroom?
Overall, how useful were the UCLA Saturday workshop activities in helping you implement this laboratory experiment in your classroom successfully?

* 7. Did any part of the experiment work poorly or cause problems? If so, what could be done differently?

* 8. What content did you emphasize?

* 9. Where does the Magnetic fluids lab fit in your curriculum?
