AP by the Sea
June 18 - 21, 2018
University of San Diego, San Diego, CA

Resources:

• Tyler DeWitt--Hydrogen Bonding & Common Mistakes -- This is a video suggested by one of the participants. Tyler has many other videos as well for chemistry.
• Desmos,com -- A free graphing utility online. Alex and her students use this and can plot data and share it with each other in class quickly. The data from the Blue Food Color lab could be plotted and compared before students leave the classroom. I found the following YouTube Video by a physics teacher using the graph for best fit lines helpful for total beginners, like me.
• Flinn's Free Resources -- Flinn has made many videos of demonstrations that are available on their site for free. I'm not sure of a reliable way to find them, but they are there. In addition to chemical demonstrations, there are downloadable .pdf's giving instructions as well. There are great ideas here.
• Ben Ku's Web Site -- I only mentioned Mr. Ku about a hundred times during the APSI. Here is a link to his web site.
• Large Post-It Notes -- Here is the link to popping.com where those huge post-it type notes were purchased. They stuck really nicely to the glass. I have found in my classroom that they don't stick as well to the walls. They stick nicely to a clean white board, however.
• AP Supports 2019 -- Here is the link for the College Board web site describing the new supports that will be available for the 2019-2020 school year. This includes the AP Test Bank, Unit Guides, etc.
• Extreme Glow Nightsticks -- Here is the company where I purchased those bright, short-lived light sticks for the kinetics demonstration. You need to purchase quite a few (100) to get free shipping. Remember, when they quote a price like $8.50 each, they are talking about a bag of 10 nightsticks. Keep them in the refrigerator to make them last longer.
• ReMarkable -- You might have noticed Will's electronic tablet that looks and feels like writing on paper. It is pretty cool, so I am including a link here so I will not forget to check it out.
• ROYGBV Demo Information -- Here is specific information about the demonstration with the theatrical gels (cellophane) which is an analogy for the photoelectric effect.
  Roscolux Rx25 (Lt. Red) -- (this leaks a little)
  Roscolux Rx22 (Deep Amber)
  Roscolux Rx10 (Med. Yellow)
  [Note: I put some of the Med. Yellow behind the Red and Orange windows, too.]
  Roscolux Rx 389 (Chroma Green)
  Roscolux Rx 68 (Sky Blue)
  Roscolux Rx48 (Rose Purple)
  I mentioned that there are sample booklets that contain a small sample (1.75" x 3.25") of each gel from this company. You can find them online by following the link at the beginning of this note. I did a Google search for "Roscolux sample book" and found several sources. The least expensive one ($1.50) is the one I linked above. They also sell sample books with 3" x 6" samples for about $25.
