What's Quantitative vs Qualitative data?
Quantitative is observations using measurable or countable data *Always has a number*
Quanlitative is Observations using your 5 senses

Each number represents how many kids have the animals below as their favorite animal. 
What kind of graph is this, what's the purpose of using that graph, and what animal has the least amount of kids with it being there favorite?
It is a Bar graph, it's used for compairing data, and rabbits had the lowest amount of people with that as thier favorite animal.

True or False: Mass and Weight are both constant
False: Mass is constant but weight changes
100
What is the definition of Volume?
The amount of space something takes up
100
What is a defintion of density?
Density is a physical property of matter
200
What's the defination of an Observation?
Gathering information about the world using your senses
200
What kind of Chart is this? What's it's purpose? What was the 2nd biggest country's population percentage?
It's a pie chart, It's used to show parts to a whole, and the 2nd biggest counrty's population percentage is Germnany with 18.75%

How do you measure the mass of a liquid.
First measure the mass of the container. Then add the liquid and measure the mass. Lastly subtract the mass of the container from the mass with the liquid.
200
How do you measure solids that are regular?
Use the formla
200
Densisty is a comparison of how much _____ (_____) there is in a certain amount of ______ (_______)
Density is a comparison of how much matter (mass) there is in a certain amount of space (volume)
300
A Hypothesis has to be a ______ statement? X is a _____ variable? (What is being _____) Y is a ______ variable (How you are ______)
A hypothesis has to be a If... Then... Because statement. X is a independant variable (What is being Changed.) Y is a dependant variable (How you are Measuring.)
300
What is Processed data?
Raw data that has been transformed into useful information
300
How do you measure a irregular solid's mass?
Use a Tripple Beam Balance or a digital balance
300
How do you measure irregular shaped objects?
Water displacement
300
What is the formula for density?
Density = mass ÷ volume
400
What is a control group? Also what is a Experimental group?
A control group is the group that exists under normal circumstances. An experimental group is a group that is being manipulated.
400
What kind of graph is this? What's the purpose of it? What is the lowest temperature it ever reached?
Line graph, it's used to look for changes overtime, and the lowest temperature it ever reached was 43 degrees
400
How do you measure a regular shape solid's mass?
Use a Tripple Beam Balance or a digital balance
400
What is the measurement type of irregular shaped objects?
cm³
400
What is the density measurement?
g cm³
500
What is a contstant? Also what is experimental error?
Constants are variables that must remain the same. Experimental error is human error in an experiment.
500
What does the CER stand for in the CER paragraphs. And what else should you add into your CER paragraph.
C- ___________
E- ___________
R- ___________
C- Claim; answers question
E- Evidence, at least 2-3 pieces of quantitative data
R- reasoning why
The extra thing you add is accepting or refuting your hypothesis
500
What's Mass vs. Weight?
Mass is how much matter an object has and weight is the amount of force exerted on a mass due to grvaitational pull.
500
What do you use for large amounts in volume and what do you use for percise moments?
Large amounts: Beaker
Percise Moments: Gradulated Cylinder
500
What are the rules for Density? Also what is buoyoncy
Water= 1 gcm³
If Density is greater than 1 it will sink
If Density is less than 1 it will float
If Density is 1 it suspends neutral buoynacy (middle)
If mass is less thatn volume= float
If mass is more than volume = sink
Buoyancy means whether something sinks or floats
