Solids have a definite shape and take up a definite amount of space.
Liquids take up a definite amount of space but take the shape of their container.
Gases have neither a definite shape nor do they take up a definite amount of space. Gases take up the space of the container they are in, but will
escape from a container when it is opened.

Rusting causes the texture and color of a metal to
change. Does that indicate a change to a new material or a change to a different form of the same metal?
(see pages E26-E29)

The color change indicates that a new material has formed.
When oxygen reacts with metal over a period of time, a reaction occurs which
results in the forming of a new compound called oxide.

Decide on a watering schedule and water each plant with exactly the same amount of water on exactly the same days.
Each group of plants will receive a different temperature of water, and those temperatures will need to remain consistent throughout the experiment.

A recess ball is gently set at the top of the slide on the playground. Describe its
motion if no one touches it and there is no wind.

The ball will not move without any force pushing
on it.
![Page 85: Science Objectives—Grade 4 S.4.2.1.4 S.4.2.1.3 S.4.2.1.2 S.4.1.1.1 S.4.4.1.1 S.4.4.1.3 S.4.4.2.3 S.4.4.3.1 S.4.1.1.2 S.4.2.2.1 S.4.2.3.3 S.4.6.1.3 S.4.1.1.3](https://reader036.vdocuments.us/reader036/viewer/2022062422/56649ddf5503460f94ad93b3/html5/thumbnails/85.jpg)
How would you describe the motion of the same
ball if it were given a light push down the slide?
![Page 86: Science Objectives—Grade 4 S.4.2.1.4 S.4.2.1.3 S.4.2.1.2 S.4.1.1.1 S.4.4.1.1 S.4.4.1.3 S.4.4.2.3 S.4.4.3.1 S.4.1.1.2 S.4.2.2.1 S.4.2.3.3 S.4.6.1.3 S.4.1.1.3](https://reader036.vdocuments.us/reader036/viewer/2022062422/56649ddf5503460f94ad93b3/html5/thumbnails/86.jpg)
The ball will roll down the slide when pushed gently, likely
getting faster as it goes down. The ball will continue rolling as it
exits the slide.
![Page 87: Science Objectives—Grade 4 S.4.2.1.4 S.4.2.1.3 S.4.2.1.2 S.4.1.1.1 S.4.4.1.1 S.4.4.1.3 S.4.4.2.3 S.4.4.3.1 S.4.1.1.2 S.4.2.2.1 S.4.2.3.3 S.4.6.1.3 S.4.1.1.3](https://reader036.vdocuments.us/reader036/viewer/2022062422/56649ddf5503460f94ad93b3/html5/thumbnails/87.jpg)
How would the motion of the same ball be different if a
student were to kick it down the slide rather than
push it gently?
![Page 88: Science Objectives—Grade 4 S.4.2.1.4 S.4.2.1.3 S.4.2.1.2 S.4.1.1.1 S.4.4.1.1 S.4.4.1.3 S.4.4.2.3 S.4.4.3.1 S.4.1.1.2 S.4.2.2.1 S.4.2.3.3 S.4.6.1.3 S.4.1.1.3](https://reader036.vdocuments.us/reader036/viewer/2022062422/56649ddf5503460f94ad93b3/html5/thumbnails/88.jpg)
If the ball were kicked, it would also go down the slide, but it may
bounce as it rolls downward. The harder push will cause it to move
faster. The ball will continue rolling as it exits the slide.
![Page 89: Science Objectives—Grade 4 S.4.2.1.4 S.4.2.1.3 S.4.2.1.2 S.4.1.1.1 S.4.4.1.1 S.4.4.1.3 S.4.4.2.3 S.4.4.3.1 S.4.1.1.2 S.4.2.2.1 S.4.2.3.3 S.4.6.1.3 S.4.1.1.3](https://reader036.vdocuments.us/reader036/viewer/2022062422/56649ddf5503460f94ad93b3/html5/thumbnails/89.jpg)
What if a bowling ball were placed at the top of the slide instead of a
recess ball? How would it change the force needed to push the ball down? How would it change the
motion of the ball?
![Page 90: Science Objectives—Grade 4 S.4.2.1.4 S.4.2.1.3 S.4.2.1.2 S.4.1.1.1 S.4.4.1.1 S.4.4.1.3 S.4.4.2.3 S.4.4.3.1 S.4.1.1.2 S.4.2.2.1 S.4.2.3.3 S.4.6.1.3 S.4.1.1.3](https://reader036.vdocuments.us/reader036/viewer/2022062422/56649ddf5503460f94ad93b3/html5/thumbnails/90.jpg)
The bowling ball would need a greater force to get moving. Once it was
moving, the bowling ball would move down the slide speeding up as it
rolled, just as the recess ball did. It would likely stop rolling abruptly once
it exited the slide, however, as it would be harder for an object with
such mass to change direction without an additional force.

If you were to roll two pencils across your

how would the motion of the two pencils differ?

The octagonal pencil would likely roll slower and stop sooner. The round pencil
would roll more freely, perhaps faster, and may
roll right off the desk.

conclude given his data?

conclude that the greater the weight, the fewer times a ball will bounce.
The final trial must have been in error. Kevin might need more trials
before drawing a conclusion.
