AP TIP IN
July 9 - 12, 2019
Pike High School, Indianapolis, IN

Resources:

• Tyler DeWitt--Hydrogen Bonding & Common Mistakes -- Tyler has many other videos as well for chemistry. I like his Galvanic Cells video.
• Prof Dave -- Here is another source of lectures for background content.
• Entropic Time -- Here is an amazingly clever video about Entropy that is very well made.
• 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 where he has links to the videos that accompany the Honors and AP curriculum.
• 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.
• 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.
