Air Pressure Experiment Worksheet

Science experiments lesson 6: Air pressure: the card on a glass · Set 597 · 40 questions

What you do (Air pushes): 1. Fill a plastic glass right to the top with water. 2. Lay the postcard flat on top, covering the rim. 3. Over a sink or bucket, hold the card and turn the glass upside down. 4. Slowly take your hand away from the card and watch.
