A good experiment can only have one of this type of variable.
What is the Independent Variable?
This is where you find the atomic mass on a periodic cell. (top, bottom, left, right, middle)
What is at the bottom of a periodic cell?
This type of element usually exists in a gas form. When it does not, it tends to shatter instead of bend and has a dull appearance.
What are non-metals?
This is when a substance contains only one type of atom.
What is an element?
This is the formula for density.
What is mass/volume=density?
Good experiments have many of this type of variable to ensure that the results are accurate.
What are controlled variables?
The atomic number indicates how many of these subatomic particles are in the atom.
What are protons?
This type of element is partially conductive. Otherwise, it has a mix of properties.
What are metalloids?
This substance contains more than one type of atom spread evenly throughout the material. It is often transparent.
What is a solution?
An liquid takes up 5mL of space. When measured, it is equal to 15g. This is an example of this density.
What is 3g/mL?
An example is "If the speed of a skateboard rolling down the hill is greater on steeper hills, then the same skateboard will travel a longer distance in 10 seconds on a steep hill over a less steep hill."
What is a hypothesis?
This is the symbol for the element Carbon.
What is C?
This type of element is often shiny, exists in a solid form in normal temperature conditions, and conducts thermal energy well.
What are metals?
This type of substance will seperate if left alone a long time, creating a layered look in a container.
What is a suspension?
An Oxygen atom has 8 protons. It contains a positive charge. This is the best example of how many electrons it contains.
What is 7 electrons?
A good example will answer the Experimental Question and also inform readers whether or not the hypothesis was supported or unsupported.
What is the conclusion?
You can calculate the quantity of this subatomic particle by subtracting the atomic number from the atomic mass.
What are neutrons?
Volume and Mass are not examples of this category of properties.
What are characteristic properties?
This type of substance contains more than one type of atom and the atoms are chemically bonded.
What is a compound?
This happens to substances that already dissolve easily in water when the temperature increases.
What increases solubility?
If this part of your experiment is not detailed and changes from trial to trial, you risk having inprecise or even inaccurate results.
What is the procedure?
If you have a negatively charged ion, which subatomic particle is greater (protons, neutrons, electrons)?
What are electrons?
This is where you will find noble gases on the periodic table.
What is the right?
This type of substance will not seperate over time. It is possible to seperate atoms through means that do not involve a chemical reaction.
What is a Colloid?
This is how you would measure the volume of an irregularly shaped object, like a scissors.
What is water displacement?
