In the lessons

In science lessons, «experimental» data comes from your own test; you compare it with your prediction, and keep a fair test by changing only one thing. In news, experimental medicines are being tested before doctors use them widely. In music and art, «experimental» means unusual or daring.

Examples

• The experimental method helps us test ideas fairly. tree →
• The plane is experimental and has never carried passengers. tree →
• Doctors tried an experimental medicine. tree →

• Our experimental group of plants got extra light. tree →

Note

Adjective from «experiment». In science, the «experimental group» gets the change, the «control group» does not. Stress: «ex-PERR-i-MEN-tul».
