In testing this piece of quartz, I found that it would scratch glass. What property was I testing?
-
Hardness
Yes! Hardness is a substance's resistance to being scratched. With a hardness of 7, quartz is hard enough to scratch glass. -
Cleavage
No. Cleavage is the tendency of a mineral to break along planes of weakness to produce pieces with flat, smooth sides. Cleavage involves breaking, not scratching. -
Fracture
No. Fracture is a property of minerals that do NOT break along planes of weakness to produce flat, smooth sides. This involves breaking, not scratching. -
Streak
No. Streak is a test to see the color of a mineral when it is ground into a powder by scratching it on a porcelain streak plate. For streak, we are powdering the mineral, not scratching another substance.

These flowers are so long and thin that only hummingbirds can get to the nectar. What would be the advantage of only letting certain creatures get the nectar?
-
It makes it more likely that the flower will be pollinated.
Yes! As you can see in the Flowers video, the flower needs a pollinator to carry its pollen to another flower of the same kind. If only hummingbirds can get to the nectar, they are more likely to visit other flowers of the same kind. By doing that, they carry pollen from one flower to another, pollenating them. That makes this a strong advantage for the plant. -
It keeps animals from eating the nectar.
No. The nectar is supposed to be eaten. It serves as a treat to get animals to come to the flower. -
It helps the hummingbirds get more food.
No. While getting more food would be an advantage for the hummingbirds, it would not help the plant. -
There is no advantage.
No. Flowers have specific shapes, colors, and smells for a reason.

When a scientist makes a new discovery, other scientists usually do exactly the same experiment. Why?
-
They want to get part of the credit.
No. While replicating an experiment is very important, the scientists who do it usually don't get much credit for their work unless they discover an error in the original experiment. -
Repetition is part of the scientific process.
No. Repetition is when scientists repeat their own experiment several times, not when other scientists do the same experiment. -
They think they can make changes to improve the experiment.
No. By doing exactly the same experiment, they are not changing anything. Instead, they are replicating the experiment as closely as possible. -
Replication is part of the scientific process.
Yes. By replicating the experiment, other scientists can help verify that the results are accurate. There is always a possibility that there was some unnoticed influence on the original experiment, and replication can help spot that.

I used a Density Column to show that olives are denser than cherry tomatoes. To follow proper scientific procedure, the experiment needs to be checked by repetition and replication. What is the difference between repetition and replication?
-
Repetition means that I do the same experiment again. Replication means that other people do exactly the same experiment again.
Yes! To confirm your results it is important for you to repeat exactly the same experiment again (repetition) and then for other people to do exactly the same experiment again. (replication). If any of the results from repetition or replication are different from your original data, your original results are NOT confirmed, and you need to do more work. -
Repetition means that I do the same experiment again. Replication means that I do the experiment again after correcting errors.
No. Replication is when other people to do exactly the same experiment. -
Repetition means that I do the same experiment again. Replication means that other people try to improve on my experiment.
No. Replication is when other people to do exactly the same experiment. -
Repetition means that I do the experiment again after correcting errors.. Replication means that other people do exactly the same experiment again.
No. Repetition means that I do the same experiment again.

When you break the mineral calcite, it breaks into shapes with flat, smooth sides. This is an example of:
-
Cleavage
Yes! A mineral has cleavage when it breaks to form flat, smooth surfaces. -
Fracture
No. There are different kinds of fractures, but none of them form flat, smooth surfaces. -
Conchoidal
No. A conchoidal fracture is the shell-shaped break that is commonly seen when glass breaks. A conchoidal fracture is not flat.
-
Hardness
No. Hardness tells us how easily a mineral can be scratched, not how it breaks.
