Lesson 1 & 2: ? Research Hyp
What are the steps of the scientific method in order?
1. Question 2. Hypothesis 3. Research 4. Experiment 5. Analysis 6. Conclusion
How many independent variables can you have? Why?
?One (1)
To make sure the independent variable is influencing the dependent variable.
How many trials do you need for good science?
3
What does analysis mean?
A systematic evaluation of data
What is step 1 of the scientific method?
Question
What are relevant sites you can use for research?
internet (trusted websites), books, magazines, articles, informed people (scientists, teachers)
What variable do you change on purpose?
Independent Variable
What system of measurement is used in science?
Metric
What is a visual representation of the data?
A graph!!!!
What is step 2 of the scientific method?
Research
?What information do you need to write down to cite your source?
Name of the website or book, author, title, and date
Which variable is measured at the end?
Dependent Variable
What should you do while conducting an experiment?
(2 things)
Make Observations and Collect data on a chart.
What are three types of graphs?
Line Graph, Bar Graph, Pictograph, or Pie Chart
What is step 3 of the scientific method?
Hypothesis
What is a hypothesis?
An educated guess
What are Control Variables?
Variables that stay the same
What are materials?
A detailed list of supplies needed for the experiment
What should be included in your conclusion?
Purpose of the experiment and what you learned
If your results support or contradict your hypothesis
Possibility for future study and how well your procedures worked
What is step 4 of the scientific method?
Experiment
What must a hypothesis be? (3 things)
?Clear, Brief, Testable
If I design an electromagnet experiment where I change the number of coils to see how many paper clip can be picked up. What are my independent & dependent variables?
Number of coils- independent- that's what I changed on purpose
Number of paperclips picked up-- dependent- that's what changed as a result of changing the number of coils.
What are procedures?
Step by step instructions for how to do the experiment
Which axis is the independent variable graphed on? (the one you change on purpose)
Which axis is the dependent variable graphed on?
X-Axis, independent variable (horizontal axis)
Y-Axis, dependent variable (vertical axis)
What is step 5 of the scientific method
Analysis
Step 6 is conclusion... but you knew that...
