This is such a fun lesson, you get to be Pavlov and your students get to be the dogs!You will need dixie cups, Tang powder or Lemonade powder (to get them salivating) and a bell or other stimulus. They don't need a ton of powder, just about a tablespoon or so, enough to dip their fingers and lick powder each time you ring the bell.I have the lesson timed out on a Word document along with a student page of guided notes that has the clips embedded. I have tested all links as of 3/11/20
