,Cause vs Correlation Correlation describes a relationship between two variables where changes in one
are associated with changes in the other, while causation means that one
variable directly influences the other, causing a change.
Criteria vs Constraints Criteria are the specific things a design or solution must have or do to be
considered successful, while constraints are the limitations or restrictions that
impact the design process and the feasibility of a solution.
Trade-offs Sometimes, you may need to make trade-offs between criteria and constraints,
meaning you might have to accept a slightly lower performance in one area to
achieve a better result in another.
Qualitative Data vs Quantitative Data Qualitative research explores concepts and experiences through non-numerical
data, while quantitative research measures variables and tests theories using
numerical data.
Precision vs Accuracy Accuracy measures how close results are to the true or known value, while
precision measures how close results are to one another.
Drawbacks vs Benefit 'Benefits' and 'drawbacks' are commonly used to describe the positive and
negative aspects of something, respectively.
Calculating an average formula Adding a group of numbers and then dividing by the count of those numbers.
CER The CER writing method, which stands for Claim, Evidence, and Reasoning, is a
structured approach to presenting an argument or explanation.
Design a solution A 'Design Solution' is a method or approach developed through the process of
finding the best possible solution, applying it, improving it, and eventually
replacing it with a better alternative.
Why use a model Models are representations of natural phenomena, used to explain, predict, and
understand the world around us.
Interpolation and extrapolation Interpolation estimates values between known data points, while extrapolation
estimates values beyond the known data.
LSB Regents Testing Strategies When you see the word 'and' in a question, it indicates that this is a two-part
question; you must answer both parts to earn credit.
LS1 - From Molecules to Organisms Includes standards related to structure and function of cells, body systems,
homeostasis, cellular differentiation, photosynthesis, matter cycling, and cellular
respiration.
LS2 - Ecosystems Includes standards related to carrying capacity, group behavior, cycling of matter
and energy flow, energy pyramids, disruptions, and carbon cycling.
LS3 - Heredity Includes standards related to DNA and chromosome function, variations due to
meiosis and mutations, and inheritance and expression of traits.
LS4 - Biological Evolution Includes standards related to evidence for evolution, natural selection,
evolutionary fitness, adaptation, and human activity's impact on biodiversity.
, Science and Engineering Practices (SEPs) Includes practices such as asking questions, developing models, planning
investigations, analyzing data, and engaging in argument from evidence.
Crosscutting Concepts Provide a framework for integration, encourage analytical thinking, and promote
scientific literacy in biology.
Foster Deep Understanding Exploring relationships such as structure and function, energy and matter, and
stability and change helps students gain a deeper comprehension of biological
processes.
Enhance STEM Education Crosscutting Concepts support an integrated approach to STEM education,
encouraging connections between biology, technology, engineering, and
mathematics.
Patterns Examining the structure of DNA to identify recurring sequences that determine
genetic traits, essential for inheritance and diversity in living organisms.
Cause and Effect Investigating how changes in an ecosystem, such as the introduction of an
invasive species, can lead to alterations in population dynamics and biodiversity.
Scale, Proportion, and Quantity Understanding the relative size of cells and organelles within a cell and how
these proportions affect the function of cellular processes.
Systems and System Models Modeling the flow of energy through a food web to illustrate how energy is
transferred between trophic levels in an ecosystem.
Energy and Matter Exploring photosynthesis to understand how energy from the sun is converted
into chemical energy in plants, supporting life throughout an ecosystem.
Structure and Function Investigating how the structure of the human heart supports its function in
pumping blood throughout the body.
Stability and Change Studying homeostasis in living organisms to understand how biological systems
maintain stability despite environmental changes.
Asking Questions and Defining Problems Involves formulating questions that can be investigated scientifically and
identifying problems that can be solved through engineering.
Developing and Using Models Students create and use models to represent and understand phenomena,
systems, or processes, refining them as they gather more data.
Planning and Carrying Out Investigations Involves designing and conducting experiments or observational studies to
collect data about natural or engineered systems.
Analyzing and Interpreting Data Students analyze collected data to identify patterns or trends and interpret what
the data means in the context of their initial questions.
Using Mathematics and Computational Thinking Emphasizes the importance of mathematics and computation in analyzing data,
modeling systems, and solving problems.
