Science Experiments

How about "Density Delight: Exploring the Magic of Mass and Volume"? It's inviting and captures the wonder of discovering how different materials interact in this experiment. Just like painting a happy little tree, this title will surely spark curiosity and joy in your audience.

An organism that must get food by eating other organisms is called a heterotroph. These organisms cannot produce their own food like plants do through photosynthesis, so they rely on consuming other living organisms for energy. Examples of heterotrophs include animals, fungi, and some bacteria.

Purpose means what you are trying to prove by doing that lab or experiment.
For example, if you are doing a test to see if a candle lights without oxygen by placing it under a glass, then your purpose would be something like:
"To prove that a fire needs oxygen for its chemical reaction"

For the purposes of a basic chemistry course, blending food is a physical change since it typically involves only a change in particle size to create a mixture.

There are cases where blending food causes chemical changes, for instance when mixing the ingredients to make muffins. In this case, the baking soda and acid combine to produce carbon dioxide (among other things), and certain protein substances in the flour combine chemically to form gluten.

In the simplest case, however, the blending of food is a physical change.

Paper towels are strong due to their high absorbency and ability to hold together when wet. The fibers used in making paper towels are often longer and more tightly woven than those used in other paper products, giving them increased strength and durability. Additionally, some paper towels are treated with chemicals or additives to enhance their strength and overall performance.

When cornstarch is mixed with vinegar, it makes a cloudy solution. It cannot dissolve in the vinegar, so it creates a liquid that has cornstarch particles floating in it turning the liquid cloudy.

Since you are looking at the proposition that a good balanced breakfast helps concentration then the independent variable is a good balanced breakfast.

However, if your study was simply looking at the relationship between a good balanced breakfast and concentration in school, either variable could be the independent variable. It could be argued that only by concentrating in school would you learn what a good balanced breakfast was.

No. They are two quite different things.

It could be the experimenter, someone else (in a double blind experiment) or nobody.

Sometimes yes, but often that is not considered an independent variable but simply a replication of the same experiment.

It can be but it is equally possible that the experimenter has absolutely no control over the independent variable.

For example, in studying the grades of a class in a school, the pupils' gender may be an independent variable of interest. But the experimenter cannot control that variable.

How many km are there in 600 centimeter?

1. Find a question that cannot be answered because there is insufficient context.

2. Post an answer.

3. Move on to other things.

Four normally.

It could be but need not be.

Time.

Feed, if growth of a living organism.

Three. All nonzero numbers are significant, and any zeros in between significant numbers are significant.

Any variable can be an independent variable: it depends on the context.
