Scientific Questions
Hypothesis
100
This is the first step in the scientific method
What is "Identify the Problem" or "Ask a question"
100
This is a type of observation that deals with numbers and measurement, like Ms. Rose is 5' 7'' tall.
What is quantitative observation?
100
This is a type of question that does not work well with the scientific method
What is a "Why" question or "Yes or No" question.
100
This is a good hypothesis for this scientific question "How does the temperature of water affect how fast sugar will dissolve"
IF sugar is put into hot water THEN the sugar will dissolve more quickly BECAUSE of the heat or boiling point
200
This is the second step in the scientific method
What is "Form a Hypothesis"
200
This is a type of observation that uses descriptions of qualities. For example-the book was big, blue, and heavy.
What is a qualitative observation?
200
This is the correct way to word a scientific question.
WHAT is the EFFECT of ___________ on _________? OR HOW does __________ AFFECT __________?
200
This is a good hypothesis for this testable question- Which drink causes teeth to rot the fastest: soda, fruit punch, diet soda, water, or orange juice?
If a person drinks liquids like soda or juice more often, then their teeth will rot more quickly than a person who drinks more water. BECAUSE of the high sugar and acid in soda and juice
300
The third step of the scientific method, where you test your prediction through a procedure.
What is an experiment?
300
This is a conclusion you come to based on your observation. For example-the dog is golden, THEREFORE he must be a golden retriever
What is an inference?
300
These are the independent and dependent variables in the scientific question "How does the size of a rubber band affect how far it can be shot"
What is Independent variable-SIZE (or size of rubber band) What is dependent variable-DISTANCE (distance the rubber band will travel)
300
This is a good hypothesis for what scientific question: IF the airplane is smaller THEN it will go faster than the bigger airplane BECAUSE you won’t need as much force behind the smaller airplane
How does the length of a paper airplane affect the distance it travels?
400
What you do after you've performed your experiment and have data (name the step)
What is Step number 4 of the scientific method-Analyze your data?
400
The fish was 13 cm long and weighed 200 grams.
What is a quantitative observation?
400
These are the independent variable and dependent variable in this scientific question- How does the amount of water in a pot affect how fast it boils?
Independent- AMOUNT of water Dependent -SPEED of heating
400
This scientific question "How does the speed you drive affect how much gas you use" called for this hypothesis.
What is "If you drive faster than 45 miles per hour, then you will use more gas, because you use more gas at higher speeds.
500
What you do at the very end of the scientific method, after analyzing your data (last 2 steps)
What is "Draw Conclusions" and "Communicate your results"
500
Ms. Rose wrecked her car, therefore she must have been driving carelessly
What is both an observation and an inference?
500
This is a better, more scientific way to word this question "Why does my mood change when the weather changes?"
How do changes in weather affect a person's mood? or What is the effect of weather change on a person's mood?
500
This is the form a hypothesis is written in.
What is "If____________then______________ because___________."
