1 What are you eating? Nanomaterials in food and food packaging. Yvonne Pfluger MSiC 6-12 Educator June, 2014 Conference Inquiry in Action

2 Overview Implementing Inquiry in the classroom/Intro to PlayDecidePlayDecide Logical argument and persuasive scientific writing and communication skills Introduction of discussion topic: Nanotechnology Why is nanotechnology important What is the big deal in applying nanotechnology in foods and food packaging Merging the inquiry process with background knowledge Assessing performance of teacher and students Questions, comments

3 Inquiry Using observation and collected data with manipulated variables.

4 Implementing Inquiry in the classroom How can we use it in our present lessons What benefit is it to our students.

5 Four Level Model of Inquiry 1. Confirmation 2. Structured 3. Guided 4. Open Each level is based on the amount of information provided to the students.

6 Level 1 Confirmation Research question Procedure Results and Conclusions Reflection: Why did this happen?

7 Level 2 Structured Research Question Procedure NO Results and /or conclusions are given to students—they must go through the experiment and use the science process skills to reach the answer Observing Predicting Measuring Classifying Communicating Inferring Experimenting Hypothesizing Interpreting Data Graphing Identifying Variables Controlling variables Formulating models

8 Level 3 Guided Only a problem is supplied to the student. NO procedures; NO knowledge of results.

9 Level 4 Open Students generate own question, methods, and solution!

10 Logical Argument & Persuasive Scientific Writing EXAMPLE Academic Help EXAMPLE Resource Persuade Me in 5 Slides Resource

11 Ethics “Intellectual growth occurs when people are required to exercise high-level thinking…relative to their own stage of development” Erika Lindemann

12 Selected Topic Research ethics : personal, social, conservation Social ethics: rights, justice, utility, care Communication situation: audience, subject, composer, context Relationships entail responsibility Merging the inquiry process with persuasion and ethics

13 Ethical Inventory Questions

14 Ethical Question Star Rhetorical Situations

15 What is Nanotechnology?

16 Characterization, fabrication, or manipulation of structures, devices, or materials with a dimension between 1-100nm in length

17 So What is the Importance of Nanotechnology? Applications Medical therapeutics and diagnostics, energy production, molecular computing, structural materials Research funding $15 billion worldwide Employment ,00 researchers; 6 million by end of decade Global economy impact $3 trillion by 2020
