What is the difference between solute and solvent?
A solute is the substance being dissolved and the solvent is the substance doing the dissolving.

After all of the filtration is done through your filter, can you drink it and why?
No, there are still small particles in it and you can't drink it until the chemicals that make it drinkable are added.
100
What is the hypothesis?
The hypothesis is the statement you create before doing your experiment that states what you think will happen. There is no right or wrong answer.
200
What is the independent variable?
The independent variable is the variable that is changed by the researcher and the researcher observes to see if it has an impact on the dependent variable

Electricity is the______ of electrons, because electrons______or_______ from atom to atom.
Electricity is the flow of electrons, because electrons jump or move from atom to atom.
200
What is a pure substance?
A pure substance is a substance that only has one type of particle or substance in it.

What is the first step to filtration and what happens in it?
The first step to filtration is aeration. In this step you pour water back and forth in between two cups and this allows dirty gases to escape and clean oxygen to enter.
200
What is the purpose?
The purpose is the statement stating the purpose of your experiment.
300
What is the dependent variable?
The dependent variable is the variable that changes as a result of the independent variable.

In a Series circuit, if one light is removed. What will happen?
If one light is removed from a series circuit, all other lights go out.
300
What are the different states of matter?
There are 4 states of matter.
300
What is the second step to filtration and what is happening in this step.
The second step to filtration is coagulation. In this step, alum is being added to the water and this makes the clump together so the particles of mud or dirtiness are heavy and gravity can do its magic.

What is Quantitative data?
The quantitative data is the data that can be measured with numbers.
400
What is the controlled variable?
The controlled variable is the variable that you keep the same.
400
In a parallel circuit, if one light turns off. What will happen?
In a parallel circuit, if one light is removed, all other lights stay on.
400
What is a mixture?
A mixture is a substance containing 2 or more types of particles are substances in the mixture.
400
What is the third step to filtration and what is happening in this step?
The third step to filtration is sedimentation and this is where the clumped particles sink to the bottom of the water. This is done in a time period of about 20 minutes.

What is Qualitative data?
The Qualitative data is the observations not related to quantities or numbers.
500
Who made the law of viscosity?
Isaac Newton created the law of viscosity.

What does the word circuit mean?
The word circuit means pathway or go around.
500
What is the difference between a solution and a mechanical mixture?
A solution is a mixture where you can't see the different particles or substances or can't easily separate them where a mechanical mixture is a mixture where you can easily separate the different particles or substances and see the different particles or substances.
500
What is the fourth step to filtration and what happens during it?
The fourth and final step is filtration. This is where the water moves through the filter you made and water drips through the bottom. It may be clear, but you still can't drink it.
500
What is experimental design?
Experimental design describes the manner in which you test your hypothesis through experimentation.
