CER
A statement that answers a question
Claim
The set of genes that an organism carries, represented by upper/lowercase letters
Genotype
Used to look at objects on the cellular level
Microscope
The variable that is changed or manipulated
Independent
What will be measured and observed in an experiment.
Dependent Variable
Quantitative or qualitative data/ observations
Evidence
Two of the same form of a gene, with one from the mom and the same one from the dad
Homozygous
The function of muscle tissue
Carry out movement of the body.
Variables that are purposely kept the same throughout the experiment
Constants
It functions as support and protection
Skeletal System
A scientific concept or explanation that links the evidence to the claim
Reasoning
Shows the specific trait ONLY when both parents pass the gene on to their offspring.
Recessive trait
Smooth muscle is found inside many internal organs, such as the stomach and blood vessels is an example.
Involuntary Muscle
Used for comparison
Bar Graph
Muscles under your control
Voluntary
Must support the claim
Evidence
Daily Double (800pts)
Determine the probability of the genotype (yy) using a Punnett Square where you cross two parents that are Yy.
25% or 1 out of 4
Connect muscles to bones
Tendons
What happened in the experiment
Results
Shows its specific trait, even if only one parent passed the gene on to the offspring.
dominant trait
Triple Trouble
Things a scientific explanation must include.
(500 pts for each one you list)
- a claim that answers the question
- evidence from your data
- reasoning that involves a scientific rule or principle that describes why the
Influenced both by its genotype and by the environment.
Phenotype
Getting goosebumps when you are cold is an example.
Response
Double Down (1000 pts)
Label the X and Y axis for this experiment.
Little Johnny threw three different kinds of airplanes (Paper, plastic and foam) and measured how far they flew. He made a bar graph. Tell what label he put on the X axis and what was on the Y axis.
X = Type of Airplane
Y = Distance plane flew
