Variables/Observation vs. Inference
A conclusion you develop from reasoning.
What is an inference?
In CER, this is a statement that answers the question or problem.
What is a claim?
This organelle is responsible for producing energy (ATP) in the cell through cellular respiration.
What are the mitochondria?
When body temperature rises, the body responds by sweating to cool down. This is an example of what process?
What is homeostasis?
This is the basic unit of DNA, consisting of a phosphate group, a sugar molecule, and a nitrogenous base.
What is a nucleotide?
In a plant growth experiment, the amount of sunlight given to each plant is kept the same. This is an example of what type of variable?
What are constants?
Proteins are made of these building blocks.
What are amino acids?
Unlike animal cells, plant cells can make their own food because they contain this organelle.
What is the chloroplast?
During mitosis, this phase is when chromosomes line up in the middle of the cell.
What is metaphase?
In DNA, adenine (A) always pairs with this nitrogenous base.
What is thymine (T)?
A researcher wants to test if fertilizer affects plant growth. She gives one plant fertilizer and another plant no fertilizer. The plant without fertilizer serves as what?
What is the control group?
This part of CER explains why the evidence supports the claim, often using scientific principles.
What is reasoning?
What are the two main products of photosynthesis?
What are glucose and oxygen?
This body system includes the brain, spinal cord, and nerves and is responsible for sending signals throughout the body.
This process in the carbon cycle involves plants taking in carbon dioxide from the atmosphere and using sunlight to convert it into glucose.
What is photosynthesis?
A scientist is testing how the temperature of water affects how fast sugar dissolves. What is the dependent variable in this experiment?
What is the time it takes for the sugar to dissolve?
Lipids are an important part of cell membranes because they are hydrophobic. What does “hydrophobic” mean?
What is "repels water" or "does not mix with water"?
Which molecule is broken down in cellular respiration to release energy?
What is glucose?
What happens when cells to divide uncontrollably instead of following the normal cell cycle?
What is cancer?
The two types of fermentation.
A student wants to see if listening to music affects how fast they can complete a puzzle. Identify the independent variable, dependent variable, and a possible constant in this experiment.
What are the independent variable (listening to music or not), dependent variable (time to complete the puzzle), and a constant (same puzzle used)?
What are the steps of the scientific method?
What is making an observation, asking a question, forming a hypothesis, testing the hypothesis, data and observations, and analysis and conclusion?
The cell membrane is described as "selectively permeable." What does this mean?
What is "It controls what enters and exits the cell"?
What are the 4 stages of the cell cycle in order and what are the 4 stages of mitosis in order?
What is G1, S, G2, Mitosis? What is prophase, metaphase, anaphase, and telophase?
The cellular respiration chemical equation.
C6H12O6 + O2 >>> CO2 + H2O + ATP
