PROPERTIES OF AIR

• Takes up space(paper bag)
• Has mass (ballon w/ string)
• Movement (fan)

TEST

• Choose one activity
• Make a prediction
• Test 3x
• Record data
• Describe what happened
• Explain why?

VOCAB

• Air- a mixture of many gases and dust particles,usually clear
• Mass- measurement of resistance
• Movement- change in location or position

AIR PRESSURE TEST

• Bottle + ballon
• Water + notecard
• Run w/ paper

AIR PRESSURE EXPERIMENT

• Choose 1
• Make prediction
• Test 3x
• Record data
• Summarize what happened
• Explain why

VOCAB

• Air pressure- a force, all around us, varies day to day, varies in locations
• Air pressure is also known as barometric pressure

BERNOULLI’S PRINCIPAL

• Increase in velocity will decrease pressure
• How do we know he was correct?

STATIONS

• Move through each station
• Make a prediction
• Test 3x
• Record data
• Describe what happened
• Explain why it happened

WAS BERNOULLI CORRECT?

• Faster moving air has low pressure
• Slower moving air has high pressure
• But what does it have to do with flight?

VOCAB

• Lift- raise to a higher position
• Velocity- the rate of change of position. Both speed and direction.

CAN BERNOULLI’S PRINCIPLE EXPLAIN HOW OBJECTS HEAVIER THAN AIR CAN FLY?

WING ON A STRING

• A piece of paper,paper clips, straws, fishing line, fan
• Follow instructions on handout
• Answer all questions on handout

Explain how air pressure, Bernoulli’s principle, and plane wings
Are related
