AP at the Beach
June 24 - 27, 2019
McBride High School, Long Beach, CA

Resources:

• Drum Head Vibrations -- I just found this nice, short video on YouTube that shows several of the vibrational patterns for a 2-D drum head vibrating in 3-Dimensions.  As the energy of the vibrations gets higher, there are more ways for the drum head to vibrate... just like the electron.
• Abigail Giordano Videos -- This teacher has videos that follow the chapters in both Zumdahl and Brown/Lemay.  Look at the "Playlists" section of her YouTube channel.  She sounds like a pretty traditional lecturer, but if you need a good review of a topic, this seems like a great resource.
• Tyler DeWitt: Galvanic Cells -- In 2018, people shared with me a video from Tyler DeWitt about Mistakes that students make about Hydrogen Bonding.  This year, people said that his Galvanic Cells video is very useful for students.  I like that he is very visual and takes his time as he explains these complicated cells clearly and concisely.
• Ice Sphere Maker -- Here is a pricey aluminum mold that uses the same idea as the "Incredible Ice Melting Block".  Pretty cool... literally... and they only cost $600!
• Flinn's Free Resources -- Flinn has made many videos of demonstrations that are available on their site for free.  See the photo below: Go to the Search Bar and select "Resources" from the pull-down menu and then type in the topic you are interested in.  In addition to videos of 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.
• 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.
