This is the density column from the Making a Density Column video. Notice that the olives are floating at the boundary between the water and the corn syrup. What does that tell us?
-
The olives are less dense than the water, and more dense than the corn syrup.
No. If the olives were less dense than the water, they would float on top of the water layer. -
The water is denser than the olives.
No. If the water was denser than the olives, then the olives would float on top of the water layer. -
The corn syrup is less dense than the olives.
No. If the corn syrup was less dense than the olives, the olives would sink all the way to the bottom. -
Olives are denser than water, and less dense than corn syrup.
Yes! Because the olives are denser than water, they sink to the bottom of the water layer. Because they are less dense than corn syrup, the olives float on top of the corn syrup layer.

Why is color not a reliable way to identify minerals?
-
Many minerals occur in several different colors
Yes. This is the mineral quartz. Quartz can be clear, white, black, yellow, purple, and other colors, so its color is not reliable for identification. -
It is difficult to tell the difference between color and luster.
No. Luster tells us how the mineral reflects light, and has nothing to do with its color. -
Some minerals are clear, and don't have any color.
No. Even clear minerals like quartz can be found in different colors due to impurities and imperfections. -
Actually, color is a good way to identify minerals.
No. Color is not a reliable way to identify minerals.

These cells DO NOT have a cell wall. What does that tell us?
-
These are young cells.
No. Even new cells can have a cell wall. -
These are NOT plant cells.
Yes! Plant cells are surrounded by a cell wall, which provides structure and protection. -
These are NOT animal cells.
No. Animal cells do not have a cell wall. -
These are dead cells.
No. Being alive or dead does not change whether a cell has a cell wall or not.

What season is Australia having in this graphic?
-
Spring
No. In the spring, the Earth's axis would not be tilted towards or away from the Sun. -
Summer
Yes! Australia is in the southern hemisphere, which is tilted towards the Sun. That tells us that it is summer there. -
Autumn
No. In the autumn, the Earth's axis would not be tilted towards or away from the Sun. -
Winter
No. Australia is in the southern hemisphere. If it was having winter, then the southern hemisphere would be tilted away from the Sun.

When this cannon fires, cannon and the cannon ball both move, but the cannon ball moves much farther and faster than the cannon. Why?
-
The cannon ball is smaller.
No. While smaller size means a little less air resistance, that is not enough to cause the difference. -
The wheels on the cannon are stuck.
No. Even with the wheels moving freely, the cannon ball will still move much faster and much farther. -
The cannon ball is round.
No. While the round shape means a little less air resistance, that is not enough to cause the difference. -
The cannon ball weighs less.
Yes! According to Newton's Second Law of Motion, the more mass an object has, the less it will be affected by a force. Newton's Third Law of Motion tells us that the cannon and the cannon ball will both be pushed by the same amount of force, but since the cannon is much heavier (more mass), it will not move as fast or as far.If the cannon was made of very light weight plastic, so that it was much ligher (less mass) than the cannon ball, then the cannon would move farther and faster.
