Science SRP Flashcards
What are variables?
Variables are factors in an experiment that can change or be controlled.
What is the Independent variable?
The independent variable is the factor that you deliberately change in an experiment to test its effect.
What is the dependent variable?
The dependent variable is the factor that you measure in an experiment as it responds to changes in the independent variable.
What is a reliable test?
A reliable test is one that produces consistent results when repeated under the same conditions
What is a valid test?
A valid test is an experiment that accurately measures what it is intended to measure.
What is LoC?
Law of Conservation
What is the LoC of Energy
Energy cannot be created, nor destroyed; it can only be transferred/transformed
What is a fair test?
A fair test is an experiment where only the independent variable is changed, while all controlled variables are kept the same.
How can we improve reliability?
We can improve reliability by repeating the experiment, using larger samples, and keeping methods consistent.
What is an aim?
An “aim” in an experiment refers to the overall purpose or goal of the investigation.
What is a hypothesis?
A hypothesis is a testable prediction about the expected outcome, using both if and then about variables of the investigation/ experiment.
What is a controlled variable?
Variables that are kept constant throughout an investigation to ensure reliable and consistent results.
What is an equipment list?
A detailed list of all materials and tools needed for the experiment.
What is a risk assessment?
Identifying potential hazards in the experiment and outlining safety precautions.
Do a risk assessment for a glass beaker
Hazards: (answers could include any)
- Cuts from broken glass
- Burns from heated glass
-Skin or eye irritation from spilled substances
Precautions: (Answers could include any)
- Handle with care; place on a stable surface; avoid sudden impacts
- Use heatproof gloves when handling hot beakers
- Use beakers only for appropriate substances; wear safety goggles and gloves
What is a method?
A step-by-step procedure written in PAST TENSE that explains how the experiment was conducted.
What are the results?
The raw data collected from the experiment, usually recorded in tables.
What is data analysis?
Examining the results by calculating averages and identifying trends.
What does CUTLASS stand for?
Crosses, Units, Title, Line of best fit, Axis, Scale, Size.
What is discuss in an SRP?
Analyzing results, explaining trends, discussing errors, and linking findings to scientific concepts.
What is a conclusion in an SRP?
A summary of findings that states whether the hypothesis was supported or rejected.
How do you write a conclusion in an SRP?
Restate the Aim, Summarize the Results: Highlight key trends or patterns found in the data.
State Whether the Hypothesis Was Supported: Clearly say if your results support or contradict your hypothesis. Explain Any Scientific Reasoning: Link findings to relevant scientific concepts.
What axis does the independent and dependent variable go on?
Independent on the X axis, Dependent on the Y axis
How do i format a title for a graph?
Dependent Variable vs Independent Variable
What is a risk assessment?
Identifying potential hazards in the experiment and outlining safety precautions.
What is the risk of a glass beaker?
Can break & Cause cuts
What is the precaution of a glass beaker?
Hold with both hands and place in centre of bench
What is the M in MRS GREN?
Movement
What is the R in MRS GREN that is not reproduction?
Respiration
What is the S in MRS GREN?
Sensitivity
What is the G in MRS GREN?
Growth
What is the R in MRS GREN that is not respiration?
Reproduction
What is the E in MRS GREN?
Excretion
What is the N in MRS GREN?
Nutrition
PUT IT ALL TOGETHER - What are the words for MRS GREN?
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition.
What is accuracy?
How close the measurements are to the true value
What is reliability?
How consistent the results are when the experiment is repeated.
