What's the Word?
A testable explanation for an observation.
What is a hypothesis?
A scientist asks, "Does the amount of fertilizer affect plant growth?"
→ What is this called?
Problem
The smallest marked measurement on a ruler or other measuring instrument.
What is small division?
As the amount of studying increases, test scores increase.
Direct
Information gathered using your senses or instruments.
What is an observation?
A scientist records that a plant is tall, green, and healthy-looking.
→ Is this information qualitative or quantitative?
Qualitative
Using a graph to estimate a value between two known data points.
What is interpolate?
As speed increases, the amount of time needed to travel the same distance decreases.
Inverse
The variable that you deliberately change in an experiment.
What is the independent variable?
A scientist records that a plant is 24.5 cm tall.
→ Is this information qualitative or quantitative?
Quantitative
Using a graph to predict a value beyond the known data.
What is extrapolate?
A student changes the amount of water given to plants, but every plant grows exactly 10 cm.
Constant
The variable that you measure or observe.
What is the dependent variable?
A measurement is very close to the true value.
→ Is this accuracy or precision?
Accuracy
A line drawn through data points to show the overall trend.
What is the best fit line?
As temperature increases, the amount of ice remaining decreases.
Inverse
A step-by-step plan for conducting an experiment.
What is the procedure?
Several measurements are very close to one another.
→ Is this accuracy or precision?
Precision
A data point that is unusually far from the others.
What is an outlier?
As exercise time increases, calories burned increase.
