This is called Pumice. It is formed when magma reaches the surface, and reduced pressure lets gas bubbles escape. When it cools, it has so many trapped air bubbles that it will actually float in water. 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. -
Pumice is not a rock.
No. Pumice is a naturally occurring solid that forms large layers in the Earth. Pumice is a rock.

Baking a cake is an example of:
-
A physical change
Partly right. Some of the changes involved in baking a cake are physical changes. -
A chemical change
Partly right. Some of the changes involved in baking a cake are chemical changes. -
Both
Yes! The process of baking a cake involves many changes. Some, such as water evaporating and sugar melting are physical changes. Others, such as baking powder reacting cause a change in the chemical formulas, indicating a chemical change. For more on this, read Changing How We Look at Changing -
Neither
No. There are many changes involved in baking a cake.

When water freezes, it:
-
Condenses
No. Condensation happens when water vapor changes from a gas to a liquid. -
Contracts
No. Water does not take up less space when it freezes. -
Expands
Yes! Unlike most substances, water expands to take up more space when it freezes. -
Gains mass.
No. Changing from one state to another does not cause a change in mass.

Which part of the food web does this roadrunner belong to?
-
Producer.
No. A producer captures energy from sunlight, and stores it as food. To do that, the organism needs to contain chlorophyll. -
Primary Consumer.
No. Primary consumers eat producers. In spite of what you may have seen in cartoons, roadrunners do not eat plants or bird seed. -
Secondary Consumer
Yes! Secondary consumers eat other consumers. Roadrunners are predators, and eat lizards, snakes, mice, and many other small animals. -
Decomposer
No. Roadrunners may occasionally scavenge freshly killed animals, but they are not decomposers.

Which organ produces bile to digest the fat in this bacon?
-
Liver
Yes! The liver produces bile, which digests fats. -
Gall Bladder
No. The gall bladder stores the bile, but does not produce it. -
Pancreas
No. The pancreas produces insulin to digest sugar. -
Thyroid
No. The thyroid produces several hormones which control growth and metabolism, but it does not produce bile.
