Thinking about how to plan NANO Week
posted by: soudghiri
8th grade standards:
8.1.1 Explain that all matter is composed of particular arrangements of atoms and that there
are approximately one hundred types of atoms (i.e., elements).
8.1.3 Explain how the arrangement of atoms and molecules determines chemical properties
of substances.
8.1.4 Describe the structure of atoms and relate the arrangement of electrons to how atoms interact with other atoms.
8.1.6 Explain that elements and compounds have characteristic properties such as density,
boiling points and melting points that remain unchanged regardless of sample size.
8.1.5 Explain that atoms join together to form molecules and compounds and illustrate with
diagrams the relationship between atoms and compounds and between atoms and
molecules.
Pre NANO
-Discussion of Scale
-scale game (using materials students already know and then using science materials)
-when u do the scale game write smaller to larger on the board
-after you place pictures talk about the scale which can lead into a further discussion of different scale values
-prefixes (nano 10-9, micro 10-6, milli 10-3, 1, centi 10-2, 1 micro 10-6, 1 angstrom = 10-10
-knowing the prefixes and the levels of magnitude
-learning scale in magnitudes of 10 (show a video to see a pictorial representation of scale increasing and decreasing by a factor of 10)
-practice doing conversions of scale from micro to nano using a known conversion
-knowing how to convert a number from micrometers to nanometers and from nanometers to micrometers
-David Pogue “Making Stuff Smaller”
- What is an atom, protons, neutrons, and electrons?
-Understanding of matter and what matter is made of
-physical and chemical properties of matter
-differences in properties of metals, nonmetals, and metalloids
-need to know vocabulary: semiconductors, conductors, insulators,
-history of microscopes
During NANO
DAY 1:
intro to nanotechnology
ways that nanotechnology impacts your life
-ask what are some of the big problems in our world? (clean up nuclear waste in Japan, Global warming0
-what about your health? diseases, cancer, and heart conditions
-How will we solve these problems? Using nanotechnology we will be able to solve these problems
-talk about the research that Natalie, Becky, and Michael do at Notre Dame
-talk about graduate school
DAY 2:
-review the concept of scale (talk about the width of a single strand of hair which is 100,000 nm and a buckyball which is 1 nm)
-review metric system
- Do the folding/cutting paper activity
-Do a form of scale activity using pictures the students are familiar with.
-The Difference Between a Telescope and a Microscope
DAY 3: AFM Topography Laboratory (AFM Ping Pong Ball)
DAY 4: What do you feel is in the mystery box?
DAY 5:
- demos of AFM and STM AND SEM
-graphene, graphite, bucky balls, theramine model
After NANO
-have students complete table where they summarize important information about each microscope, webquest activity, provide a list of websites to describe all the important info
-nanooze magazines
-projects (posters, powerpoint, write a children’s book
