The steps are first, forming and asking a question, second; formulating a hypothesis, experimenting, collecting data, analyzing results, and drawing conclusions.
What are the steps of the Scientific Method?

D=M/V (Density=Mass/Volume)
What is the formula for density?
100
Length x width x height
What is the formula for finding volume of a regular shape?
100
Liquid, Solid, Gas, and Plasma
What are the forms of matter? (There is an extra one)

For mass, we use a triple beam scale, units of grams. Weight is measured generally with a spring scale, and etc. you can find, units of newton. 1 newton=1000 grams.
What do we use to measure mass and weight? Give the units of measurement too. Give a conversion of the unit of mass and the unit of weight.
200
Your question must be testable, measurable, and actually let you learn something through the experiment/ not a useless and odd question. The question comes from your observation- information gathered from the 5 senses.
What are requirement standards of the QUESTION you must make in the Scientific Method?

Density is the measure of the amount of mass in a given volume, and according to how much mass, we can determine things like if it can sink or float and more measurement comparisons.
What is density, and why is it important?
200
Volume is the amount of space that matter in an object occupies, or in an amount of space- how much space matter occupies.
What is volume? Explain in your own words.
200
Matter is anything that has mass and takes up space. Some examples are air, water, crystals, clouds, and wind.
What is MATTER? Give some examples.
200
Mass is the amount of matter in an object, or basically the weight and how much the atoms and molecules are in a form of solid, liquid, gas, or plasma.
What is mass? Explain more in depth.

An observation is information that you know (learned) and have gathered through your 5 senses. Because our 5 senses can detect many things, there are two types of observations- Quantitative and Qualitative. Quantitative and Qualitative Observations are both gathered with your 5 senses (AKA, both necessary and main observations), but one is described with numbers and measurement, and the second one is gathered by smell, feel, touch, look, hear, etc. After you make an observation, identify it, and gather all the info, you can infer what happened- question/hypothesis.
What is an observation, and what types of observations are there? Compare and Contrast the two, and then tell what you do next.
300
Density can be measured with all matter- which includes liquids, gases, and solids. Solids are measured by gram/1cm3, and gases+liquids are with gram/1mL. Since density is the measure of the amount of mass in an object, (mass is measured in grams) so every bit of mass is with 1 cm3 or 1mL.
What are all the standard units of density and why?
300
Water Displacement is a method to find the volume of an irregular object like a rock or a chess piece, where you fill a graduated cylinder with a measurable amount of water and then put the object in, to measure its volume. Subtract that old water amount from the new one to get the volume of the object. It works because 1 mL=1 cm3, and water is basically a big mass of volume, when you add volume, it increases.
What is water displacement, and why does it work?
300
Molecules, atoms, existence.
What consists of matter (liquids, solids, and gas)?

Weight is the measure of the amount of gravitational pull on an object, and is measured in Newtons. 1 N= 1000 grams. Since weight depends on gravity, it can change from place to place as long as the amount of gravity that exists in the place changes. Like the moon for example- it has less gravity than the earth, so on earth, it seems to weigh more than the moon
What is weight, what is it measured in, and why does location matter? Give an example.
400
VARIABLES are any factors that can change during an experiment, so if we identify the variable that is changed, and the variable of the data, we can make a successful experiment that coordinates and responds/answers our question.
Why do we need to identify the independent and dependent variable, and compare/contrast the two.
400
Density is the amount of mass, or grams in an object, and weight is a measure of the gravitational pull on an object. If I have something that is 10000000000 Newtons, it might float because of its mass to make the density of the object to be greater than the density of water to make it float.
What is the difference between density and weight?
400
No, because if we had a bowling ball and a balloon- two objects with about the same amount of volume, the bowling ball has more matter (molecules and atoms) than the balloon.
Are volume and mass going to be the same in every situation?
400
Matter is anything that takes up space and has an amount of atoms/molecules (mass), light and sound don't take up space, and cannot be measured in grams for mass (they don't have matter in them, so no mass).
Why are light and sound NOT matter?
400
Objects with similar sizes and volumes can have different masses because mass is the measure of the amount of matter in an object, and objects with the same size can be made up with different amounts of matter because of the molecules and atoms that make it up. A good example is a bowling ball and a balloon.
Why can objects with similar volumes have different masses? Give 1 example.
500
We use the Scientific Method to let us so that we can have accurate, useful, unique, exciting and new knowledge about the world of science. It also can let us run experiments that will be successful.
Explain the Scientific Method and why we use it.

The difference between mass and density is that density is in a given amount of space (in this case, on unit of an object) it measures the amount of mass in that one little amount of space (1g/1cm3), and mass is how much matter there is in an OBJECT. The similarities of the two is that mass and density are that they are relating to a mass of ONE object.
What is the difference/similarities between density and mass?
500
Volume is not area, since area is for plots of land, plain shapes, and it is a measurement of an amount of a unit in measure. Volume is the measure of how much SPACE an object's matter takes up.
Can volume be area?
500
Matter is the same everywhere, and in this case, this is a cycle of the same material going through different states of molecule grouping to make new states, but still from same thing of material. The difference is simply the state the material and the grouping of the molecules is in.
The water cycle is a cycle of matter. What are the differences and similarities of the matter in water, vapor, and ice?
500
Mass is the amount of matter in an object, units of measure is grams, and it uses a triple beam scale. Weight is the measure of the amount of gravitational force on an object, unit of measure is the Spring scale, and uses newtons. Both mass and weight are dependent on the amount of particles in a given amount of space or object, though.
Compare and contrast weight and mass.
