Scientific Method
A testable prediction (educated guess)
What is a hypothesis?
Technique using the 5 senses that may lead to asking a question that directs an experiment.
What is an observation?
The amount of matter (stuff) in an object.
What is mass?
Lab equipment used to measure mass.
What is a scale or triple beam balance.
What are three types of graphs?
Line, Bar, Circle (pie chart), Scatter plot, Pictograph
An organized procedure for testing a hypothesis.
What is an investigation or experiment.
Factor that does not change in an experiment.
What is the constant?
The amount of space an object takes up.
What is volume?
Tool used to measure volume of irregularly shaped object.
What is a Graduated cylinder?
Graph that shows how a relationship between two variables changes over time.
What is a line graph?
Explain why the scientific process is not a rigid, linear sequence of steps.
Answers will vary:Science is messy!
Variable that is manipulated during an experiment and plotted on the x-axis of a graph.
What is the independent variable?
A comparison of mass and volume.
What is density?
Technique to find volume of a box or cube.
What is length x width x height?
A visual display of information or data.
What is a graph?
The six major stages of the process of scientific inquiry.
What are: Ask question (problem), Form hypothesis, Design an experiment, Collect and interpret data, Draw conclusions, Communicate to others....Research goes with all parts!
Variable that is measured during an experiment and plotted on the y-axis of a graph.
What is a dependent variable?
Equation to calculate density.
What is mass divided by volume?
How you read a graduated cylinder.
What is "eyeball the meniscus" on a steady, level table?
Graph that is used to show how a whole is broken down into parts.
Circle graph or pie chart
Why is it important to make specific, detailed measurements using SI units in science?
SI units are universal (across countries) and are easier to convert. Making specific, detailed measurements allows your data to be more accurate so your conclusions are as well.
Process that uses investigation and observation to gain knowledge about events in nature.
What is science?
Calculate the density of 5 marshmallows if their mass is 5 grams and their volume is 15 cm3.
What is 0.33 g/cm3
In an investigation you put a beaker of water in the sun and measure the temperature every 10 minutes for 1 hour. What is the dependent variable?
Temperature of the water.
