Activity
Fill one bowl with warm water, another with cold water, and a third with water at room temperature. First, have the students place the fingers of one hand in the warm water. Wait 60 seconds. Then have them place their fingers in the room temperature water and describe the temperature of the water (feels cool). Then have the students place their fingers of the other hand in the cold water. Wait 60 seconds. Then have them place their fingers in the room temperature water and describe the temperature of the water (feels hot). Remind students that hallucinogens can affect the way we perceive reality.
