  1. LIVE INTERACTIVE LEARNING @ YOUR DESKTOP NSDL/NSTA Web Seminar: Small Creatures Under the Microscope—The Exploratorium Tuesday, February 20, 2007 7:00 p.m. to 8:00 p.m. Eastern time

  2. http://nsdl.org http://nsdl.org • Access to real research and experts • Video and digital images to visually enhance your teaching • Dynamic, microscopic views of life under the lens http://exploratorium.edu

  3. Small Creatures Under the Microscope - the Exploratorium http://nsdl.org

  4. Today’s Presenters Dr. Kristina Yu Dr. Sherry Hsi Dr. Karen Kalumuck

  5. Microscope Imaging Station at the Exploratorium http://nsdl.org

  6. The MIS Website - a digital resource for microscopic images http://nsdl.org • Features of the MIS website: • an overview of contents & types of images • About our topics - 3 examples: • zebrafish, sea urchins & stem cells 3.Using images to stimulate inquiry: an example

  7. http://nsdl.org Do you have access to good-quality compound microscopes? Stamp your answer. Elementary & Middle School? High School & Above?

  8. http://nsdl.org Let’s do a poll question! How many students share a microscope when using them in your classroom? • Zero • 1 student per microscope • 2-4 students per microscope • More than 4 students per microscope

  9. www.exploratorium.edu/imaging_station (insert screenshot of homepage here)

  10. www.exploratorium.edu/imaging_station http://nsdl.org Features: Articles about researchers & their work, multimedia related to the story Gallery : A collection of still images and movies highlighting organisms and cells used in biomedical research. Activities: Conversation provoking, image- based activities and Teacher Institute tested activities to be added soon!

  11. It’s Time to Play: Name That Cell! http://nsdl.org 1 2 3

  12. www.exploratorium.edu/imaging_station http://nsdl.org Images & movies available in the gallery

  13. Which of these is the wildtype? Stamp your answer

  14. How often do you use images from the web in your classroom? (0 = never, 5 = occasionally, 10 = the Web is my primary source) Type your answer in the box Elementary & Middle School High School & Above

  15. Zebrafish (Danio rerio) • Commonly found in freshwater aquariums • Widely used in basic & biomedical research • Clear eggs are good for studying developmental processes • Adult fish produce dozens of eggs at a time

  16. Zebrafish development: How long do you think this process takes? http://nsdl.org Write Your Guesses on the Chat

  17. Zebrafish are used to study cardiovascular diseases http://nsdl.org Mutant heart Normal heart *Note: You will need to download the free version of Quick Time to view these movies. Normal heart with green fluorescent protein

  18. Sea urchins Lytechinus pictus • Clear eggs • Can collect sperm & eggs separately to time fertilization • Embryos will develop synchronously

  19. Sea urchin development http://nsdl.org

  20. stem cells http://nsdl.org (Mouse embryonic) Pluripotent mouse stem cells Cardiac myocytes derived from mouse stem cells Neural cells derived from mouse stem cells *Note: You will need to download the free version of Quick Time to view this movie.

  21. Images for Inquiry Human white blood cells Sea urchin embryo Xenopus embryos Mouse embryonic stem cells Zebrafish embryo Amoeba Elodea cells Human red blood cells Human cheek cells Which images are of differentiated cells, that is, specialized for a specific function? What are their functions?

  22. Images for Inquiry Human white blood cells Xenopus embryos Sea urchin embryo Mouse embryonic Stem cells Amoeba Zebrafish embryo Human red blood cells Elodea cells Human cheek cells Which images show cells that are not differentiated? Do you think they will continue to develop and specialize? What might they become?

  23. More topics coming soon! • Xenopus (African clawed frog) as a • model for vertebrate development • Planaria as a model for regenerative • medicine • Neural connectivity in Zebrafish • Cancer & the link to stem cells • Cell cycle and mitosis
