Steps of Scientific Inquiry
What number step of the Scientific Inquiry Process is make an observation and ask a question?
step 1
Items needed to do the experiment
Materials
What will happen to my weight if I eat too many cookies?
What is the dependent variable?
Weight
I see 5 marbles
Is this an observation or an inference?
Observation
What were the materials needed in the Rescuing Ralph Lab?
Ralph (gummy worm), life saver, boat (cup), toothpicks
What is the second step of the Scientific Inquiry Process?
Form a hypothesis
An educated guess based on your observations that answers your question
Hypothesis
What will happen to my weight if I eat too many cookies?
What is the independent variable?
Number of cookies eaten
I see 5 marbles
Is this a qualitative or quantitative observation?
Quantitative
What are the three branches of science?
Life Science, Physical Science, Earth Science
What is step 3 of the Scientific Inquiry Process?
Conduct the experiment to test your hypothesis
Part of the experiment that changes
Variable
What will happen to my weight if I eat too many cookies?
What is a hypothesis you would form for this question?
(must be in if then format)
If I eat too many cookies, then my weight will increase.
What is an inference you could make after hearing thunder?
Multiple correct options
What are two of the lab rules in class?
Follow written and spoken directions & procedures
Behave like a scientist & use equipment correctly
Work collaboratively with your lab partner(s)
Clean up your lab station & materials
Don’t eat anything without permission
During which step of the Scientific Inquiry Process would you write down the data shows...
Step 4 (record data and results and analyze them)
Summary of the experiment and results
Conclusion
Does the number of strands of spaghetti affect how many pennies the spaghetti can hold before breaking?
What is the independent and dependent variable?
IV - number of strands of spaghetti
DV - number of pennies
Does adding salt to water affect the time it takes water to boil?
Would you record this data using a bar graph or a line graph?
Bar graph
What are the four classroom expectations in class?
Be kind - treat yourself and others with respect
Be safe - follow directions & rules for equipment and in labs
Be responsible - come to class prepared to learn & participate
Try your best - it’s okay to fail, it’s not okay to not try
What are steps 5 and 6 of the Scientific Inquiry Process?
Step 5 - Draw Conclusions
Step 6 - Communicate your findings
The method scientists use to ask and answer questions about the world around them
Scientific Inquiry
If I bake my cookies longer Then the cookies will be flatter
What are the independent and dependent variables based on this hypothesis?
IV - time in oven
DV - height of cookies
Does the number of strands of spaghetti affect how many pennies the spaghetti can hold before breaking?
Would you use a bar graph or line graph to record this data?
Line graph
Name the IV, DV, hypothesis and analysis of the Gum Chewing Lab
IV - type of gum (chewed or not)
DV - weight of gum
hypothesis - I chew gum, then its weight will be (more, less or stay the same)
analysis - the data shows that chewing a piece of gum makes it lighter in weight
