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.

Which of these is NOT an arthropod?
-
A: Horsefly
No. Arthropods have an exoskeleton, a segmented body, and jointed legs. Like other insects, horseflies are arthropods. -
B: Fiddler Crab
No. The Fiddler Crab has an exoskeleton, a segmented body, and jointed legs. That tells us that they are arthropods. -
C: Snail
Yes! The body of a snail is not segmented, an does not have any legs, much less jointed legs. It is NOT an arthropod. Instead, it belongs to a group of mollusks called gastropods. -
D: Praying Mantis
No. The Praying Mantis has an exoskeleton, a segmented body, and jointed legs. Like other insects, a Praying Mantis is an arthropod.

Why are trees an important part of the water cycle?
-
Trees need water.
No. While trees do need water, that is not why they are part of the water cycle. -
Transpiration
Yes! In order to get nutrients up to the top of a tree, it has to let water evaporate from its leaves. This process is called transpiration. One tree can put hundreds of gallons of water into the air as water vapor every day. -
Trees help prevent erosion.
No. While trees can help prevent erosion, that is not why they are part of the water cycle. -
Condensation
No. Trees are not a major source of condensation.

This is called Obsidian. It is formed from molten lava that cools so quickly that it forms a natural glass instead of crystals. What kind of rock is it?.
-
Igneous
Yes! Igneous rocks formed from magma or lava. This is an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. This is not a sedimentary rock. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. Instead of being changed, this got hot enough to completely melt, so it is not metamorphic. -
Obsidian is not a rock.
No. Obsidian is a naturally occurring solid that forms large layers in the Earth. Obsidian is a rock.
