• biking helmets are shaped to ________ drag.
• the ________ of an object has a large effect on the resistance on it.
• how can big, heavy planes fly? the air gets ______ back by the large fans. air is pushed ____ and ____ while the plane is pushed ____ and ______

Explanation:

These are fill-in-the-blank questions about properties and behaviors of fluids, a topic in physics. Each blank is completed based on core concepts of fluids, states of matter, and fluid dynamics.

Answer:

• Fluids flow, like water.
• Everything we touch is either a solid, liquid, or a gas.
• Liquids and gases are fluids.
• We can move through fluids, like swimming.
• The marbles are like particles of a solid.
• Fluids are less dense (when heated), that's why they rise. Then, they sink when they cool down.
• When a solid passes through a fluid there is drag (friction).
• Biking helmets are shaped to reduce drag.
• The shape/surface area of an object has a large effect on the resistance on it.
• How can big, heavy planes fly? The air gets pushed back by the large fans. Air is pushed down and back while the plane is pushed up and forward.
