IQWST: How Can I Smell Things From A Distance: Learning Set 3

How did the ammonia molecules get to the paper? Choose all that apply. (TWO) (MS-PS1-4) (PICK 2)

• Some of the ammonia molecules traveled up the side of the container.

• The ammonia molecules condensed and went into the air.

• The ammonia molecules evaporated and went into the air.

• Some of the ammonia molecules move or travel through air.

How is using your model to predict similar to using your model to explain? How is it different? (MS-PS1-4) (PICK 2)

• Both tell about phenomena. Both are backed by evidence. 

• Both tell about phenomena. Evidence is used only when you use your model to explain.

• When you use a model to predict, you are trying to figure out what is going to happen based on what you already know.

• When you use a model to predict, you are trying to figure out what happened.

• When you use a model to explain, it is based on what happened, or based on evidence.

• When you use a model to explain, you are trying to figure out what is going to happen based on what you already know.

What does the temperature of a substance tell about the speed of the particles? Choose all that apply.  (MS-PS1-4) (PICK 2)

• When you heat a substance, the particles in that substance move slower.

• When you heat a substance, the particles in that substance move faster.

• When you cool down a substance, the particles in that substance move faster.

• When you cool down a substance, the particles in that substance move slower.

How does cooling/heating affect the speed of molecules? Choose all that apply.  (MS-PS1-4) (PICK 2)

• When you cool a substance, the speed decreases. 

• When you cool a substance, the speed increases. 

• When you heat a substance, the speed decreases.

• When you heat a substance, the speed increases.

How does cooling/heating affect the number of collisions?  (MS-PS1-4)

• When you cool a substance, the number of collisions increases. When you heat a substance, the number of collisions decreases. 

• When you cool a substance, the number of collisions decreases. When you heat a substance, the number of collisions increases.

• Different temperatures do not affect the number of collisions.

• When heat is added, some of the empty space between the molecules is used up so that the molecules are forced to be closer to together so there are more collisions due to the crowding of molecules.

How does the temperature affect how hard the molecules hit the surface of the balloon?  (MS-PS1-4)

• If the balloon is cooled, then the molecules would not hit the surface of the balloon as hard. If the balloon is heated, then the molecules would hit the surface of the balloon harder.

• If the balloon is heated, then the molecules would not hit the surface of the balloon as hard.  If the balloon is cooled, then the molecules would hit the surface of the balloon harder.

• Different temperatures do not affect how hard the molecules hit the surface of the balloon.

• When the temperature of the balloon is increased, the balloon gets softer so that the collisions do not appear to impact the balloon as much as when the balloon is cooled.
