Sterngrr, Safety, SRM Flashcards
Scientific Inquiry Steps
Observe, define the problem, form a study question, research the problem, hypothesis, experiment and gather data, analyze results, reflect on findings, communicate on findings
Scientific method def
A logical problem solving technique
What do you do during observation
Use 5 senses, not opinionated, create inferences
What is a hypothesis
A if …, then … statement, problem statement, compares variables
What are the variables
Independent, dependent, and constant
What is the independent variable
The KNOWN
Changes unrelated to other factors-what we make or on purpose
Dependent variable
The UNKNOWN
Changes related to other factors-trying to figure out
Constant
Does NOT change throughout the experiment
Value stays the same
Graph def
Helps visualize numerical data
Bar graphs
Shows comparisons between OBJECTS
Pie graphs
To compare PARTS of a WHOLE
Line Graphs
Show the RELATIONSHIP between OBJECTS
Sterngrr stands for
Synthesis, transport, excretion, regulation, nutrition, growth/development, respiration, reproduction
Amoctooo
Atoms, molecules, organelles, cells, tissues, organ, organ systems, organism
Carsmog
Cells, adaptation, reproduction, stimuli, metabolism, organized, growth
CER
Claim, evidence, reasoning
Synthesis is
How organisms build necessary molecules
Transport is
How organisms move things to cells
Excretion is
How organisms get rid of their waste and maintain homeostasis
Respiration is
Gas exchange; to convert food to energy
Ex plants
Nutrition is
How organisms break down and absorb foods
Growth and development is
Getting larger for periods of rapid and dramatic change for others
Reproduction is
Making more of an organism
Ex: mitosis, asexual/sexual
Regulation is
How organisms control body processes
Homeostasis
Ex: heart rate, sweat, shivering
