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.

When water freezes into ice, its volume increases. What happens to its mass?
-
It increases.
No. When water freezes, it takes up more space, but the mass stays the same. -
It stays the same.
Yes. When water freezes, it expands to take up more space, but its mass stays the same. Mass is the measure of how much "stuff" is there. Freezing water does not create new water or add more "stuff". It just makes the water take up more space. -
It decreases.
No. The mass stays the same, even when the water freezes. -
Water does not have mass.
No. Everything that is made out of matter has mass.

Which part of your body comes closest to serving the same function as a plant's roots?
-
Mouth
Yes! The main functions for most plant roots is to anchor it in place and to take in water and nutrients from the soil. We do not need anything to anchor us in one place, but we use our mouth to take in water and nutrients. -
Feet
No. A plants roots anchor into in place, keeping it from moving. Your feet do not do that. -
Lungs
No. A plant takes in air through its leaves, not through its roots. -
Skeleton
No. Your skeleton supports your body and protects your organs. In plants, this is done by the cell walls. The cell wall around each cell of a plant make it stiff, supporting stems, leaves, flowers, and other parts of the plant.

When you mix cornstarch and water, you get something that many science sites call Oobleck. Under pressure, it feels like a solid, but when the pressure is removed, it flows like a liquid. What state of matter is it?
Answer:
This is a mixture, made up of particles of solid matter surrounded by a liquid. The mixture is not a single state of matter.
This is an important concept to understand, and it is seen in many things we use every day. A good example is the Egg States video, showing how a mixture of liquid and gas can seem to be a solid.
Before you try to decide if something is solid, liquid, gas, plasma, or some other state of matter, first make sure that it is a pure substance, and not a mixture of different states.
