Scientific Method vs. Science and Engineering Practices
This step of the scientific process involves asking a testable question, such as how sunlight affects plant growth.
What is forming a scientific question (or problem)?
Id both variables:
Maria tests if adding different amounts of liquid fertilizer to tomato plants makes them grow taller over two weeks.
What is :
Independent Variable: Amount of fertilizer
Dependent Variable: Height of the plants
Collects evidence without changing a variable.
What is Other investigations
Science is study of the _______ world.
What is natural.
All models have this.
What are limitations.
Scientific questions ask this. (#2)
What are questions of how or why?
Id independent and dependent variables:
Marcus builds four paper airplanes out of different types of paper (construction, printer, cardstock, and tissue) to see which design flies the greatest distance.
What is:
Independent Variable: Type of paper
Dependent Variable: Distance flown
Scientists collect observations in a consistent way over time or across locations.
What is systematic observations.
Cannot be answered with evidence alone.
What is thoughtful but not science
Scientists use these reliable sources to gather information. What are they? (#2)
What is text and media
This variable is the single factor that the scientist intentionally changes.
What is Independent variable.
Id independent and dependent variables in the scenerio:
Maya places ice cubes on surface materials like wood, metal, and plastic to measure how long it takes for the ice to melt completely.
What is :
Independent Variable: Surface material
Dependent Variable: Time taken to melt
This involves tracking variables carefully to measure their effect.
What is an experiment.
This best describes scientists?
Scientists can have different strengths and interests.
Comparing data from different investigations helps scientists notice these. (#3)
What are similarities, differences, or possible errors.
This helps scientists represent ideas that may be too large, too small, or too complex to study directly.
What are models.
Id independent and dependent variables:
David wants to know how he can make bubbles last longer before popping he adds different brands of liquid dish soap to water to test it out.
What is
Independent Variable: Brand of dish soap
Dependent Variable: Time before the bubble pops
A planned and organized procedure for observing with senses or measurement tools.
What is systematic observations.
Uses evidence from observations, measurements, or investigations.
What is Science?
A strong explanation uses this to connect a claim to evidence.
What is scientific reasoning.
Two groups conduct the same experiment but get different results. What should they do next?
What is compare methods and data.
Sarah wanted to see how study time affects her quiz score. She studied for 10, 20, 30, and 40 minutes for four separate spelling quizzes.
What is:
Independent Variable: Amount of study time
Dependent Variable: Quiz score
A test or procedure that has controlled conditions.
What is an experiment.
This can improve a test so it is more fair.
What is creativity
Scientist use this to better understand data.
Whats are:
numbers,
calculations,
measurements,
graphs, and
patterns.
