Visualizing with Models
This represents an idea, event, or object to help people better understand it.
What is a model?
This is defined as the distance between two points. For additional points, tell me the units that go with this as well.
What is length and the meter?
Described as a ratio that is equal to one and is used to change one unit to another.
What is a conversion factor?
Described as a visual display of information or data, this is often used by scientists to detect patterns.
What is a graph?
Described as an organized set of investigation procedures, scientists use this as a basis for their exploration of phenomena.
What is the scientific method?
When science is applied to help people it is referred to as this.
What is technology?
This is an exact quantity that people agree to use to compare measurements.
What is a standard?
How long, in centimeters, is a 3,075 mm rope?
What is 307.5 cm?
Name 2 of the common graph types.
What are:
Line graph
Bar graph
Circle graph/Pie Chart
Scientists aim to reduce this, which is what occurs when a scientist's expectations change how the results of an experiment are viewed.
What is bias?
When an object or event is very small and blown-up to better explain it, it is called this type of model.
What is a scaled up model?
Name the three basic units of the Metric System and what each measures.
What is:
meter - length
liter - volume
gram - mass
How long, in kilometers, is 100,000 cm?
What is 1.0 km?
This variable is graphed on the x-axis and is an important factor in scientific experiments.
What is the independent variable?
The standard by which the test results can be compared to is referred to as this.
What is the control/control group?
An explanation of things or events based on knowledge gained from many observations and investigations is called this.
What is a theory?
Described as the mass per unit volume of a material. It's value can be found using the equation D = M/V.
What is density?
What is the volume of a box that is 4 cm x 6 cm x 5 cm?
What is 120 cm3?
Because the points on a line graph are related to each other, we do this.
What are connect the points with a line?
This is a factor that changes as a result of changes in the other variables. It is placed on the y-axis of a graph.
What is the dependent variable?
Describe one of the limitations of Science.
Science cannot answer questions about emotions and/or values.
Science can predict if you like something, but not if others will like something.
Which is longer: A yard or a meter?
What is a meter?
What is the density of an object that weighs 10 g and has a volume of 100 mL?
What is 0.1 g/mL?
This type of graph is used to show how some fixed quantity is broken down into parts with the whole graph representing the total.
What is a circle graph/pie chart?
Name 3 of the 6 steps of the scientific method.
