Explain the following and what is their title? Theme 3 Prompt 500 Points Explain the following and what is their title? Lift Drag Gravity Thrust

Theme 3 Response 500 Points What is… The Four Forces of Flight Lift – Upward force which acts against the force of gravity Drag – Resistance or friction that acts to slow down an object as it moves through a gas or liquid Thrust – The force that causes an object to move forward Gravity – Downward force which acts against the force of lift. This force increases as the mass of an object increases

If you were to pour water into each flask, what would happen? Theme 5 Prompt 100 Points If you were to pour water into each flask, what would happen?

Theme 5 Response 100 Points What is only a small amount of water will go into flask A because the air cannot get out.

If you try to pull the bag out of the jar, what will happen? Theme 5 Prompt 200 Points If you try to pull the bag out of the jar, what will happen?

Theme 5 Response 200 Points What is the air inside the jar is of lower pressure that the air outside of the jar.

If you blow through the horizontal straw, what will happen? Theme 5 Prompt 300 Points If you blow through the horizontal straw, what will happen?

Theme 5 Response 300 Points What is the higher pressure of the atmosphere pushes down the surface of the water forcing the water up the straw toward the lower pressure.

Theme 5 Prompt 400 Points In a closed contained, have a beaker ¾ full of baking soda and vinegar and light a candle to the left. What will happen over time?

Theme 5 Response 400 Points What is because carbon dioxide is heavier than air it will pour out of the beaker and settle into the bottom of the tray. As the gas spills out of the beaker it will fill the container, cut off the supply of oxygen and put out the flame.

Theme 5 Prompt 500 Points What would happen if you held a hairdryer at the lower end of the ramp and used it to hold the cars up the ramp?

Theme 5 Response 500 Points What is the car with large, flat, square panels has a greater air resistance and the car with a smooth aerodynamic design has less air resistance and requires less power to cut through the air. The aerodynamic car will reach the end of the ramp first.
