Observation, Inference, and Classification
This is the method where scientists organize observations in a meaningful way by grouping objects with similar characteristics.
What is Classification?
Amount of matter in a substance (number of particles in a substance)
What is Mass?
Picture of a mathematical relationship between two or more factors. It can show a large amount of data in a simple diagram.
What is a graph?
Uses powers of ten to express numbers that would be more difficult to write or read using standard decimal numbers.
What is scientific notation?
A measure of the amount of matter (mass) within a given space (volume)
What is Density?
These events have no pattern to occurrences and are difficult to predict
What are non-cyclic events?
Amount of space an object takes up.
What is volume?
This axis is the horizontal line, independent variable
What is the X- axis?
How fast or slow a change occurs
A rock has a mass of 20 grams and a volume of 5 mL. What is the density of this rock? Show your work.
What is 4.0g/mL
This is when scientists draw conclusions based on observations
What is inference?
In Earth Science, we typically use the this system of measurement
What is the Metric System?
Shows how the dependent variable is changing.
What is the line?
When comparing lines on a graph, the steeper the angle of the line, the rate of change is this.
What is greater?
This is the equation for Density.
What is Density = Mass / Volume?
An observation made with an instrument consisting of a number and unit.
What is measurement?
To determine the volume of an irregularly shaped object, use this method.
What is water displacement method?
This type of graphical relationship, as the independent variable increases, dependent variable increases.
What is direct variable?
This is the calculation for Rate of Change.
What is Change in Value/ Time?
Two factors affect density and one of them is this.
What is Temperature?
What is Pressure?
Information gathered through the use of the five senses (sight, touch, taste, smell, and hearing)
What is observation?
The number of centimeters in 1 meter.
What is 100 cm?
This type of graphical relationship, as the independent variable increases, the dependent variable changes in a predictable pattern.
What is a cyclic relationship?
The age of Earth is 4,600,000,000 years; express this number in scientific notation.
What is 4.6 x 109 years?
Unlike other substances, waters density is highest in this form.
What is liquid?
