What is the function of the fluffy, white part of the milkweed seed?
- 
It protects the seed from insects.No. Insects could easily eat the seed, even with the fluffy top.
- 
It helps hide the seeds from birds.No. The white fluff actually makes it easier for birds to find the seeds, but the moving air from their wings also helps spread the seeds.
- 
It gathers pollen.No. The seed has already been pollinated before the fluff develops.
- 
It causes the wind to spread the seeds.Yes! The fluffy part of the seed acts like a parachute to let the seeds blow long distances with the wind. This spreads the plant's seeds over a large area.

I wanted to test a new fertilizer, to find the best concentration for my garden. I divided my garden into four sections and put a different amount of fertilizer in each section.
My test results showed that using 10 grams of fertilizer per gallon made the plants grow faster and bigger. To follow proper scientific guidelines, what should I do next?
- 
Apply 10 grams of fertilizer per gallon to all the plants in my garden.No. While that might make my garden grow well, it would not provide more evidence that this was the best mixture of fertilizer
- 
Do the same experiment over again.Yes! Repetition is an important part of the scientific process. If my hypothesis is correct, I should get the same results every time I repeat the experiment.
- 
Do the same experiment, but use a different fertilizer.No. Using a different fertilizer would be testing a different variable. I wanted to find the best concentration of the original fertilizer, so testing a different fertilizer would not help with that.
- 
Publish my results, so that other scientists could replicate my experiment.No. Replication is an important step, but I should repeat my experiment several times to be sure that I get consistent results before I ask other scientists to try replicating it.

This is called Quartzite. It was once sandstone, but heat and pressure changed it by fusing the grains of sand to each other, making it much harder. What kind of rock is it?.
- 
IgneousNo. Igneous rocks formed from magma or lava. That would have melted the sand grains. This is not an igneous rock.
- 
SedimentaryNo. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. When it was sandstone it was a sedimentary rock.
- 
MetamorphicYes!. This quartzite been changed by heat and pressure from a different kind of rock. It is metamorphic.
- 
Quartzite is not a rock.No. Quartzite is a naturally occurring solid that forms large layers in the Earth. Quartzite is a rock.

This baby praying mantis looks very much like its mother, but not exactly. What does that tell us about its life cycle?
- 
It does not undergo metamorphosis.No. While it does look similar to its parents, it lacks wings and other features which it will have as an adult.
- 
It has incomplete metamorphosis.Yes! It has most of the features of an adult, and will gain the final adult features later in its life.
- 
It has complete metamorphosis.No. For complete metamorphosis, the larva looks very different from the parent.
- 
It skipped metamorphosis.No. While it does look similar to its parents, it lacks wings and other features which it will have as an adult.
