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.

After I rubbed this ballon against my hair, it stuck to the side of my head. Why?
-
The balloon stuck because I don't have enough hair.
No. While much of my hair is gone, I still have enough to do this experiment. -
The balloon stuck because the balloon had the same charge as my hair.
No. Two things with the same electrostatic charge will repel, pushing apart. -
The balloon stuck because the balloon had a different charge from my hair.
Yes. When I rubbed the balloon against my hair, electrons moved from my hair to the balloon. The extra electrons gave the balloon a negative charge, and the missing electrons left my hair with a positive charge. Opposite charges attract, so the balloon stuck to my hair. -
The balloon stuck because my hair was magnetized.
No. Rubbing a balloon against something does not magnetize it. Even if it was magnetized, a magnet would not attract the rubber balloon.

Why does this grasshopper have such small wings?
-
Because this species does not fly.
No. This species of grasshopper does fly. -
Because it has a mutation.
No. This is a normal grasshopper, not a mutant. -
Because it is a cricket, not a grasshopper.
No. This is a grasshopper. -
Because it is not an adult.
Yes! Grasshoppers have incomplete metamorphosis. The immature grasshoppers look similar to adults, but have some differences. The immature stages of the grasshopper has small wings, but the adult stage has large, functional wings.

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.

Which of the following forms of ice commonly occurs in the summer when air temperatures are well above freezing?
A: Hail
B: Snow
C: Frost
D: Freezing rain
Think about it, and when you think you know the answer, then click here.
While other kinds of frozen precipitation can form at high altitudes, in the summer they usually melt long before they reach the ground. Hail is made up of large enough chunks of ice that it usually remains frozen all the way to the ground, even during warm weather.
