In our bottle flipping challenge experiment, which of the following is constant (something that we kept the same)?

• A. mass and gravity

• B. volume (amount of water)

• C. hand used and hand movement

• D. rate or speed of rotation

In the bottle flipping challenge experiment that we decided to do in our class, which of the following is our control (the material that we use to compare results and to which no independent variable has been applied)?

• A. No control group

• B. the bottle with 0 mL water (no water)

• C. the bottle with 100 mL water

• D. the bottle with 200 mL or 300 mL water

A type of challenge consists of spinning a bottle, partially filled with water, and making it land upright.

• A. ice bucket challenge

• B. bottle flipping challenge

• C. peer pressure challenge

• D. rock, paper, and scissors challenge

When you hold the bottle from the top, the water and center of ____________ rest in the base of the bottle.

• A. angular momentum

• B. gravity

• C. mass and weight

This scientific principle is similar to rotational force, which is a fancy word for how much energy a rotating object has.

• A. Angular momentum

• B. Fluid dynamics

• C. Mass and weight

When the bottle flips or spins, the angular momentum is transferred to the heavier water. The bottle's spin is slowed.

Which scientific principle has caused the bottle flip or spin to slow down?

• A. Angular Momentum

• B. Weight

• C. Rotational force

When water gets to the other side of the bottle, the mass of that other side increases; thus, that shifts (changes) the center of gravity.

Which of the following has caused the shifting of the center of gravity?

• A. the change of mass of one side to another side

• B. the change of rotation

• C. the change of fluid dynamics

A bottle without enough water doesn't have enough mass to remain stable when you drop it. A bottle with too much water is also unstable because the center of gravity is farther from the base. A bottle that's about 1/3 full has just the right amount of mass to keep it stable and make it land upright.

Which of the following explains why the nearly unspinning bottle falls with gravity and lands straight upright?

• A. no water or too little amount of water

• B. too much amount of water

• C. just the right amount of water
