6th Grade Roach Middle School Science Unit 1 CBA
Terms in this set (44)
Involves making observations, asking well-defined questions, formulating testable hypotheses, and using appropriate equipment and technology.
How to test a hypothesis
test by conducting an experiment
What the experiment is trying to answer.
What do you want to find out?
Cause and Effect statement. If (cause)... statement of what you think will happen.
Prodedure with Variables
Any factor that affects the outcome of your results.
What will we do to test our hypotheses? This should include an explanation of how you use your materials and step-by-step instructions on how you will conduct the investigation.
Observation / Data Collected
What happened in your experiment? Organize your information into some type of table and/or graph.
Analysis / Results
How does the data reflect your hypothesis?
Based on the data collected: What is the answer to the question? Is your hypothesis correct? What do the results mean?
Manipulative Variable / Independent Variable
The factor system being investigated that is DELIBERATELY CHANGED to determine that factor's relationship to the responding variable. (Ex: steps, sunscreen)
Responding Variable / Dependent Variable
The factor of a system being investigated that changes in response to the manipulated variable and is measured. (Ex: light)
Parts or conditions of the experiment that must remain the same.
The untested component to which you compare/measure the success of your experiment. (Ex: no sunscreen)
Size (advantages and limitations of a model)
Model can be smaller or larger than what it is representing.
Scale (advantages and limitations of a model)
Model is created mathematically proportional to the real object (Ex: 5cm on a map = 5km on Earth).
Properties (advantages and limitations of a model)
Color, shape, texture, odor, state, etc.
Materials (advantages and limitations of a model)
What is it (the model) made of?
Should be used in all fields of science to analyze, evaluate, and critique scientific explanations.
Need to include:
A descriptive title.
Lables for X-axis and Y-axis
Units for X & Y axis
Equal intervals between lines
Independent variable on X axis (MIX)
Dependent variable on Y axis (DRY)
Plot dots where value of x-axis and value of y-axis intersect.
Connect dots or draw line of best fit.
Tables and graphs
Should be made from repeated trials and should identify trends and patterns.
Used to represent data that has no order. Data has names not numbers.
Change over TIME or shows trends.
Used to represent continuous data (has a definite order with values in-between). Both asix usually have numbers.
Used to shoe percentages.
Demonstrate the parts that make up a whole.
Can be used to formulate reasonable explanations, communicate results and conclusions supported by the data, and predict trends.
mg, g, kg
The amount of matter that something is made of.
It's value does NOT change with the object's location in the universe.
The amount of space something occupies.
The amount of space something contains.
IMPORTANT-liquids change shape and assume the shape of the container.
Length (metric system)
mm, cm, m, km
degree C (Celsius)
A measure of hot or cold something is.
Amount of ENERGY in an object. the hotter something is, the more energy it has.
Space between 2 things in a straight line
How to collect and record data
Collect and record data using the metric system (International System of Units).
When collecting and recording data, what all numbers need
all numbers need an SI unit
should be used to collect, record and analyze data.
Tool to measure Mass
triple beam balance
Tools to measure Volume
Graduated Cylinder (for accurate measurements)
or Beaker (for ballpark measurements)
Tools to measure Length
ruler or meter stick
Tool to measure Temperature
Preventative safety equipment
is important when doing science. (Be able to identify the safety symbols found in your science notebook).
a scientific discipline
Relate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content.
Types of protective clothing / safety equipment
Closed Toe Shoes
When something (Ex: a block) is put into water, and the water level rises. This is because the block is taking up space, and the water has to move somewhere, and the only place to go is up.
3 types of Scientific Investigations
Descriptive Scientific Investigation
Involves collecting qualitative and/or quantitative data to draw conclusions about a natural or man-made system such as rock formation, animal behavior, clouds, bicycles, and circuits;
Observations are recorded but no comparisons are made and no variables are manipulated.
Comparative Scientific Investigation
Involves collecting data on different organisms/objects/features, or collecting data under different conditions, which cannot be controlled (Ex: time of year, air temperature, location) to make comparison; no variables are manipulated.
Experimental Scientific Investigation
Involves designing a "fair test" in which variables are actively manipulated, controlled, and measured, in an effort to gather evidence to support or not support a casual relationship.
