What is a claim in a CER?
(Answer: A statement that answers the question or problem.)
Name one characteristic of life.
Answer: Made of cells / Reproduction / Use of energy / Growth and development / Respond to stimuli / Homeostasis
What is a unicellular organism?
(Answer: An organism made of one cell.)
What is a variable in an experiment?
(Answer: Something that can change or be changed in an experiment.)
What is the first part of the Cell Theory?
(Answer: All living things are made of cells.)
How does evidence support a claim?
Answer: Evidence provides information or data that supports the claim and shows it is true
Give an example of how living things respond to stimuli.
(Answer: A person pulling their hand away from a hot surface.)
Give an example of a unicellular organism.
(Answer: Amoeba or bacteria.)
What is the control in an experiment, and why is it important?
(Answer: A control is the part that doesn't change. It’s used for comparison.)
What is the second part of the Cell Theory?
(Answer: Cells are the basic unit of life.)
What is reasoning in a CER?
Answer: Reasoning explains why the evidence supports the claim, linking the evidence to scientific concepts
Why is homeostasis important for living organisms?
(Answer: It keeps conditions stable within cells, allowing organisms to survive and function properly.)
What is a multicellular organism?
(Answer: An organism made of many cells.)
What is the difference between qualitative and quantitative data?
(Answer: Qualitative is descriptive, quantitative is numerical.)
What is the third part of the Cell Theory?
(Answer: All cells come from pre-existing cells.)
In an experiment where plants grow faster with more sunlight, what is the claim?
(Answer: Plants grow faster with more sunlight.)
How do living things obtain and use energy?
(Answer: Living things obtain energy through food (or sunlight for plants) and use it to perform life processes like moving, growing, etc.)
Why do multicellular organisms have specialized cells?
(Answer: To perform different functions, making them more complex and efficient.)
Why do scientists use the scientific method?
(Answer: To solve problems or answer questions systematically.)
What does it mean that cells are the basic unit of life?
(Answer: Cells are the smallest structures that can carry out all life functions.)
Give an example of evidence and reasoning from the sunlight and plant growth experiment.
Answer: Evidence: Plants receiving more sunlight grew 10 cm taller. Reasoning: More sunlight increases photosynthesis, leading to faster growth.)
Give an example of a living organism growing and developing.
(Answer: A caterpillar growing and transforming into a butterfly.)
How do unicellular organisms carry out all life functions?
(Answer: They perform all life functions within a single cell.)
What is a hypothesis, and how is it different from a conclusion?
(Answer: A hypothesis is an educated guess; a conclusion summarizes the experiment results.)
What does the Cell Theory tell us about where new cells come from?
(Answer: New cells come from pre-existing cells.)
