numbers
conclusion
was it true or false
inference
conclusion based on evidence
theory
explain
What is an example of quantitative data?
NUMBERS-Data that deals with numbers. Measurement
What is an example of qualitative data?
WORDS-Description- Grass is green
Where does the independent variable & dependent variable go respectively on a graph?
IV- goes on the bottom
What is an example of an independent variable?
Something that we purposely change-
IV: Percentage of fertilizer
DV: The height of the plant
The metric system is based on what multiple(multiply by what base)?
Powers of 10
List some units of the metric system
Distance/Length- Meter
Mass- Grams
Volume- (liquid)- liters
How is length measured in the metric system? What unit?
meter
How is mass measured in the metric system? What unit?
gram
How is volume measured in the metric system? What unit?
liter
How is temperature measured in the metric system? What unit?
Celsius
What tool do you use to measure length?
Ruler or meter stick
What tool do you use to measure mass?
scale
What tool do you use to measure temperature?
thermometer
What are some of the rules during a lab that one should follow?
Wear PPE- goggles, closed toed shoes, gloves, tie hair back
What is an example of an observation? What is an example of inference from that observation?
It is cloudy outside- observation–Inference- It may rain today?
What are the steps to the scientific method?
Make observations
Ask questions
Research
Create hypothesis
Experiment
Collect data
Conclusion
Share data
What is the format for a hypothesis?
IF (IV)
Then the DV
Because
What are the parts of a graph?
Title- DV as a function of IV
IV- labeled with units on the bottom
DV- labeled with units on the side
What is the volume of the rock below?
Measure the water in the graduated cylinder. Then add the rock and measure the liquid.
Then subtract the two measurements for the volume of the rock.
IF it is a square shape you just have to multiply the L x W x H.
