Which of the following observations is NOT scientifically testable?
- 
Butterflies have pretty wings.Yes! Pretty is an opinion, and can vary from person to person, so it is NOT scientifically testable.
- 
Butterflies have six legs.No. This could be tested by counting the legs of a variety of butterflies.
- 
Butterflies can sting like bees.No. A claim does not have to be true to be testable. Examination of a variety of butterflies would show that they do not have stingers.
- 
Most butterflies drink nectar from flowers.No. This could be tested by observing the feeding habits of butterflies.
Explain more about it.
If I said that butterflies did not have six legs, you could show me physical evidence by counting their legs. After counting the legs, the physical evidence would show that butterflies have six legs.
If I said that I don't think butterfly wings are pretty, you could show me wings that you think are pretty, but I might not agree with your opinion. "Pretty" is not something that we can measure. What is pretty to one person might not be pretty to another, so it is not a testable property.

This is Halite, also known as table salt. It was formed when ancient seas dried up, leaving layers of salt behind. What kind of rock is it?.
- 
IgneousNo. Igneous rocks formed from magma or lava. The Halite was not melted, and is not an igneous rock.
- 
SedimentaryYes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. Halite was deposited in large layers by water, which means that it is a sedimentary rock. Halite is also a mineral, and is one of the few rocks/minerals that we eat.
- 
MetamorphicNo. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. It is not metamorphic.
- 
Halite is not a rock.No. Halite is a naturally occurring solid that forms large layers in the Earth. Halite is a rock.

Are the ocean waves crashing against this rock an example of:
- 
ErosionPartially right! This is an example of erosion. Sand and bits of the rock are being moved by the waves..
- 
WeatheringPartially right! This is an example of weathering too. Weathering is when a rock is broken into smaller pieces. The waves and the sand they carry are slowly grinding away these rocks.
- 
Both erosion and weatheringYes! The rock is being broken into smaller pieces by the waves (weathering), and the pieces are also being carried away by the waves (erosion).
- 
Neither erosion nor weatheringNo. Both weathering and erosion are happening here.

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.
