5. To have urate an accurate test results
3. Mass is a measurement of how much matter is in an object and weight is a measurement of how hard gravity is pulling on that object to earth.
1. Becouse it is more accurate than an beaker.
2.You would use the triple beam balence.
3.Mass doesn’t change with gravity but wieght does.
5.So you can submit accurate data for your investigation.
1. graduated cylinder because it is exact
2. triple beam balance
3. mass is the amount of matter
weight is the gravitational pull
1.A graduated cylinder.
2.A triple beam balance.
3.The difference between mass and weight is mass never changes.
1. Would you use the spring balance of a graduated cylinder to measure liquid?
– no because a graduated cylinder is used to find the volume of a liquid, when a spring balance is used to measure weight.
2. Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples?
– I would use a triple beam balance to compare the mass of two minerals because the triple beam balance us used to weigh an object when a thermometer is used to measure the temperature.
3. What is the difference between mass and weight?
– mass is the amount of matter that is in an object and weight is the amount of mass
4. Why is a hypothesis important in performing a scientific experiment.
– because the hypothesis is you estimated guess that you use to base your experiment on.
5. Why is it important to collect accurate data in an investigation?
-so that you can trace your experiment, repeat it, or find your mistakes.
1. Would you use the spring balance of a graduated cylinder to measure liquid? Explain.
2. Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples?
a triple beam balance. idk y u would use a thermometer to measure sumthn when its used 4 c-n how hot it is or how hot sumthn is
3. What is the difference between mass and weight?
mass nevr changes weight can change @ any moment
4. Why is a hypothesis important in performing a scientific experiment.
so evrybdy knows wut u r thinkn wen u do your experiment
5. Why is it important to collect accurate data in an investigation?
so wen u do the samples in the lab or wherevr, u dnt mess up what the scientists are doin in the lab
1. Would you use the spring balance of a graduated cylinder to measure liquid?
2. Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples?
triple beam balance because that measures mass
3. What is the difference between mass and weight?
mass is the amount of matter in an object, weight is the amount of force that gravity has on an object
4. Why is a hypothesis important in performing a scientific experiment.
a hypothesis is important in a scientific experiment because it gives you a lead on to what you are researching
5. Why is it important to collect accurate data in an investigation?
so that you get accurate results
1) You would use a graduated cylinder because they have markings for acurate measurement.
2) You would use a tripple beam balance because they have weights that acurately measure the mass of an object.
3) Mass is the ammount of matter in an object ( this never changes) Weight is the ammount of gravity on an object (this changes where the object is)
1 graduated cylinder because it can actually contain the fluid
2 Triple beam balance because a thermometer measures temperature
mass is the amount of matter in an object, weight is how much gravity effects an object
1. graduated cylinder because it measures liquid percise
2. triple beam balance
5. you want to collect accurate data so if someone did this experiment they would get the same results
1. No, there is no need for a spring balance to measure liquid. The graduated cylinder is what you use to measure the liquid with.
2. Triple Beam Balance
3. A persons mass never changes but in areas with different gravitational pulls could make you weigh more or less.
4. A hypothesis is important in prefroming a scientific experiment because it IS what you are testing. If your hypothesis is to see if cotton obsorbs more than wool then that is basically what you are testing, your whole experiment is to test your hypothesis.
5. It is important to collect accurate data in an investigation because if you data isnt correct then your results wont be correct.
3- The difference between mass and weight is that mass the amount of matter inside an object and weight it the gravitational pull on an object. Mass never changes but weight can.
4- Hypothesis is important because you have to make an idea and prove it right or wrong. Forming one helps you learn.
5- It is impportant to collenct accurate data because something big could depend on your data, and so you won’t mess up your expirement if it depends on this information.
. Would you use the spring balance of a graduated cylinder to measure liquid? Explain.
The Graduated cylinder because it is round and can home liquid while the scale can not.
2. Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples?

4. Why is a hypothesis important in performing a scientific experiment.
It helps yoou find exactly what your looking for by asking a question
5. Why is it important to collect accurate data in an investigation?
because the expermiment would not be correct if the data was messed up
1. Would you use the spring balance of a graduated cylinder to measure liquid? Explain.
you would use a graduted cylinder because it has accurated measurements and you cant measure liquid on a blanace.
2. Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples?
you would use a triple beam balance becasue you measure the temperature with a thermometer.
5. Why is it important to collect accurate data in an investigation?
it is important to collect accurate measurements because if they are not accurate than most likely your answer or outcome will not be correct.
3. mass is the amount of matter something contains. wight is how heavy something is.
4. a hypothesis is important because you have to have a reason to do a expirement.
5. if you dont collect accurate data then the experiment would be useless.

2.triple beam balance
3.mass is the amount of matter in an object wieght is how much it wieghs
4.because it is really an educated guess
5.because if you don’t get all of the data you could miss up in the investigation
1.No, because liquid cnat be measured by weight.
2.triple beam balance
3.Mass is how big something is, weight is how much it weighs
4.So you can guess what the final result will be.
5.Because you dont want to collect wrong information.
1. yes
2. no
3. Mass is a measure of how much matter an object has. Weight is a measure of how strongly gravity pulls on that matter.
4. to find out what your looking for.
5. to have the correct answer.
1) A graduated cylinder because the liquid would not be able to stay on the balance while the graduated cylinder is designed to hold liquids.
2) A triple beam balance because a thermometer is used to measure temperature, but a triple beam balance is used to compare the mass of two objects.
3) Mass is the amount of matter in an object and never changes. Weight is the gravitational pull of an object and varies depending on where you are in the universe.
3.mass measures how big something is and wieght measures how much it weighs
5.so you can know the answer at the end of the investigation
2.triple beam balance

4.you need a question to make an experiment
5.So you know what ur talking bout
1. No it weighs weight or force
2. The thermometer
3. Mass is a measure of how much matter an object has. Weight is a measure of how strongly gravity pulls on the matter.
4. The hypothesis is the statement you are trying prove wrong
5. To do the experiment right and to have the exact date or it could all be messed up
3. Mass is the total amount of matter in an object while weight is the gravitational pull on an object.
4. A hypothesis is important during an experiment because if you hadn’t of asked a question then thought of what the answer could be, you wouldn’t be doing the experiment in the first place. Also you need to start somewhere when experimenting so that you have something to go on.
5. You should collect accurate data because after the experiment is over and you want to see what exactly happened, you won’t have the correct results so you will have to do the experiment again.
1. Grandulated cylinder because a scale is used for measuring wieght, and a grandulated cylinder is used for measuring liquids.
2. A triple beam balance.
3. mass is the amount of matter in an object, and weight is the force of gravitational pull on the earth.
4. because it could be a correct guess of the experiment.
5. because unaccurate data can throw off the experiment
2. To compare the masses of two mineral samples, you would use the triple beam balance. The thermometer measures temperature, sillyy!
3. Mass is the amount of matter in an object. Weight is the amount of gravatational force on an object. Although your weight may change, your mass always stays the same.
4. A hypothesis is important in an experiment so that the scientist can predict his own outcome of the experiment. It helps the scientist get to know the experiment, and it helps him test his knowledge as well.
1. I would use a graduated cylinder for liquid because it has markings for liquid and the spring balance is for weight.
2. I would use a triple beam balance to compare the mass of 2 mineral samples because a thermometer measures temperature not mass.
3. The difference between mass and weight is that weight depends on gravitational force on an object and mass is just a measure of the amount of matter in an object. Also, mass is measured in kilograms and weight is measured in pounds or ounces or newtons.
1. Would you use the spring balance of a graduated cylinder to measure liquid? Explain.
No the spring balances measure the weight not the volume of the liquid.
2. Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples?
A triple beam balance because it measures the mass of items, and a thermometer measures the temperature.
3. What is the difference between mass and weight?
Mass is how much matter is in the object and weight is how much gravitational force is being exerted on the object.
4. Why is a hypothesis important in performing a scientific experiment.
The experiment is the testing of a hypothesis so there would be no experiment wihtout a hypothesis.
5. Why is it important to collect accurate data in an investigation?
Inaccurate data could change the outcome of the experiment and could change your conclusion.
1) Graduated cylinder because the graduated cylinder is made to measure liquids.
2) A triple beam balance because it measures mass.
3) Mass is the amount of matter in an object and weight is the gravitational force on an object.
4) A hypothesis gets you started so you know what to test.
3. What is the difference between mass and weight? Weight is how much an object weighs based on gravitational pull and is measured in lbs., oz., or N, and mass is the quantity of matter inside an object also measured in kilograms.
4. Why is a hypothesis important in performing a scientific experiment.
Because without a hypothesis then you would have no experiment to test.
5. Why is it important to collect accurate data in an investigation?
Because if you dont collect accurate data then your end results may end up false.
1. No the graduated cylinder measures the liquid.
2. Triple beam balance
3. Weight is the measure of mass in pounds. mass is not a measure but is what makes up matter.
4. The hypothesis is the educated guess or prediction, therefore you must have a hypothesis to conduct an experiment.
5. If you do not collect accurate data than your conclusion and experiment will be wrong.
1. Graduated cylinder because it measures and holds liquid.
2. Tripple beam balance.
3.Mass is a measure of how much matter an object has. Weight is a measure of how strongly gravity pulls on that matter.
4. So if you get it wrong you’ll know why.
5. To get a fair judgement on the situation thats being investigated.
3. mass is measured in grams and weight is the gravitational pull towards earth measured in lbs, kilos, and newtons.
4. Because a hypothesis is what your testing or improving. (ex. Pouring 15 ounces of acid into water will increase the heat index faster than pouring 10 ounces of acid into water)
5.inaccurate data could lead to a faulty experiment for the next tester. could create hazards in the way of performing an expirement.
1. Graduated cylinder, it is open, and can hold liquids. A spring balance measures resistance.
2. Triple beam balance, thermometer is used to measure temperature (the “thermo” in thermometer), while a triple beam balance measures which of two objects has a greater weight.
3. Mass is the amount inside an object, while weight is the amount of force gravity exerts on an object.
1. yes because it would give you an accurate measurement.
2. triple beam balance, you cant measure solids with a thermometer.
3. mass is density, weight depends on the gravitational pull.
4. its your educated guess, it helps you figure out what you need to do differently.
5. if your data isnt accurate you could jeopardize the whole investigation.
1.yes. because it is used for measureing liquids.
2.triple beam balance
3.mass is howmuch your body is and what it is made up of.and weigh is how much something weighs.
4.because you need to make observations to form it and ask questions if you dont understand.
5.to see what the out come is of your obbservation to see if its corect.
1. A graduated cylinder because they are marked for accurate measure of liquid.
2. a triple beam balance
3. mass is the amount of matter in an object, and does not change due to location; weight is the amount of gravity excerted on an object and can change due to location in the universe
3. mass is the volume acopaying a space and weight is how heavy something is.
4. Because it may give you a better understanding from what is going to happen, or questioning.
5.Because if you may not end up with the right answer, or you may get confused.
2.Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples? triple beam balance
4. Why is a hypothesis important in performing a scientific experiment?
So you can test out what you think is going to happen.
5. Why is it important to collect accurate in an investigation?
So you can prove or disaprove your hypothesis and if you don’t get accurate data then you results could be wrong.
3. Mass is the measure of how much weight in an object while weight is the measure of the gravatational pull on an object.
4. A hypothesis is important in performing a scientific experiment because without it you have no expected outcome.
5. It is important to collect accurate data in an investigation because if you record something wrong the whole experiment could change and go wrong.
1. Would you use the spring balance or a graduated cylinder to measure liquid? Explain. You would use a graduated to measure the volume of the liquid. Graduated cylinders measure volume while spring balance measures mass of solids. Graduated cylinders is measured in milliliters while spring scale is measured in grams.
2. Would you use a thermometer or a triple beam balance to compare the mass of two mineral samples?
triple beam balance
3. What is the difference between mass and weight?
Mass is the amount of matter in an object while weight is the amount of gravitational force on an object. So, if you were to travel to the moon your weight would change because the pull of gravity is weaker there than on Earth but, your mass would stay the same because you are still made up of the same amount of matter.
4. Why is a hypothesis important in performing a scientific experiment.
The hypothesis is important because it determines if the experiment is true or false. You have no experiment with no hypothesis.
5. Why is it important to collect accurate data in an investigation?
It is important to collect accurate data in an investigation because it could cause the whole experiment to be false by just making a few of the statements incorrect.
