Organizing Data
Give an example
100
Equipment used in the lab to measure length in millimeters, centimeters, or meters.
What is a ruler?
100
A graduated cylinder would be best to use to get this info about a liquid.
What is volume?
100
This is a possible explanation or answer to a scientific problem that can be tested.
What is a hypothesis.
100
A visual representation of data show how something has changed over a period of time.
What is a line graph?
100
Give an example of something used to give an objects mass
What is triple beam balance or electronic balance
200
The curve at the surface of a liquid where you always take a measurement from.
What is the meniscus?
200
This is a measurement you take to know how much matter is in an object.
What is mass?
200
When an idea is accepted as true because it is supported by repeated evidence this is what the scientific world calls it.
What is a theory?
200
This is where you would put the independent variable on a line graph.
What is the x-axis?
200
Give an example of three things we wear in lab to protect ourselves.
What is lab apron, safety goggles, glove, long-sleeved shirt, long pants, closed toed shoes.
300
The part of the microscope that adjusts the amount of light.
What is the diaphragm?
300
This the proper way to smell a chemical if called for in an experiment.
What is wafted to the nose with your hand?
300
This is the type of data that is measured, as opposed to qualitative data which is descriptive.
What is quantitative?
300
This is how we show data that are parts or percentages of a whole.
What is a pie graph (or circle graph)?
300
Give an example of being accurate.
A scenario where the experimental value that is close to the true value.
400
Before an experiment this is what you want to make sure all equipment is checked for that so that readings will be accurate. For example you want a balance to read 0 grams if there is no object on it.
What is calibrated?
400
Petri dishes, commonly filled with agar and nutrient solutions, are used for this.
What is to grow and observe bacteria cultures
400
These are two factors that would make an experiment LESS scientifically valid. (6 possibilities)
What is uncalibrated equipment, one member in test group, no control group, not controlling all factors, making assumptions, or unable to repeat the experiment.
400
This is the type of trend you see in a graph where the dependent variable increases to a point and then begins to decreases as the independent variable increases.
What is a peaking trend?
400
Give an example of a good question that is answerable by science.
Will vary.
500
Types of gloves you would NOT wear around open flames. (2 answers possible)
What is latex or nitrile?
500
This is the type of microscope I would use if I were highly trained and needed to observe a dead object in black and white with excellent resolution.
What is electron microscope?
500
A scientist entered an experiment with a preference for a specific outcome. This is how we describe his personal opinion in science.
What is biased?
500
This is the type of graph you use with data that has different quantities between different groups and is not continuous.
What is a bar graph?
500
Create a scientifically valid experiment using this scientific problem: "I've heard someone say the length of a goldfish is determined by how large its tank is. Is this really true?
1. Control group - standard fish bowl 2. Experimental group - smaller fish bowl, large fish tank 3. Gather data with a ruler (same type of ruler in same units each measurement) 4. Measure fish at same time intervals 5. Give fish all the same type and amount of food and feed at the same time. 6. Have more than one fish and fishbowl/tank in each size.
