1.This step gives an investigation a specific direction or focus
Observation
Question
Hypothesis
Analysis
As researchers begin their study, they must examine what they already know about their topic of investigation. Based on that information, they form a hypothesis. The hypothesis is
a conclusion about what is going to happen in the experiment.
a question about what is going to happen in the experiment.
a guess about what is going to happen in the experiment.
a prediction about what is going to happen in the experiment.
Writing the hypothesis in the “if†and “then†format makes it
Easier to predict
More accurate to analyze
Testable
Hypothetical
If a scientist gathered all the data and information and then based on the data they have, they tell us “what the data indicates†happened. This is
concluding
Predicting
Analyzing
Supposing
When we conduct and experiment, the condition we are investigating, the one thing we want to know about is called the
Question
Hypothesis
Control group
Variable
The group of experimental subjects which is left “natural†or left unchanged is called the
Control group
Experimental group
Hypothetical group
Testable group
The group of experimental subjects which has the one condition changed is the
Control group
Experimental group
Hypothetical group
Testable group
Match each 1:
Metal, Styrofoam
Will different surfaces affect the melting rate of an ice cube?
Materials feel warm or cool to the touch
Wood
The materials tested were at room temperature. Since body temperature was warmer than the room temperature, heat will be lost to the material in direct relationship to its Density. Styrofoam, as the least dense, felt closer to body temperature and didn't lose much heat. However, it was the best insulator and maintained the ice cube the longest.
The material that felt the coolest melted the ice the fastest.
Different counter surfaces
Measurement of melting time
Same sized ice cubes, flat surfaced materials and equal mass
If an ice cube is placed on the surface of each material, then the material that feels warmest will melt the ice cube the fastest.
A) Experimental group (warmer or colder than body temperature)
B) Controlled conditions
C) Question
D) Preliminary observation
E) Data collected
F) Analysis
G) Control (closest to body temperature)
H) Hypothesis
I) Conclusion
J) Variables
List the basic steps of the Scientific Method in order.
plz plz help me this is my study guide 4 a test on monday so plz plz help me i really need it.
