Robb Shared "Trial Picmonics" - 25 Picmonics
With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing. Whether you're studying for your classes or getting ready for a big exam, we're here to help.
Trial Picmonics
Plant Growth Experiment
- Independent Variable
- Dependent Variable
- Dependent variable shows the effect of the independent variable
- Control (Constant) Variable
- Other Variables
- Water
- Pot Size

Chromosome and DNA
- DNA is the blueprint for building an organism
- A chromosome is packed with DNA
- Chromosomes exist in pairs
- Humans have 23 chromosome pairs
- Chromosomes are found in the nucleus
1 min
Measurements and Tools
- Volume is measured in millileters (mL) by a Graduated Cylinder
- Mass is measured in grams (g) by a Triple Beam Balance
- Time is measured in seconds (s) and minutes (min) by a Stopwatch
- Distance is measured in millimeters (mm), centimeters (cm), and meters (m) by a Ruler
- Temperature is measured in degrees Celsius by a Thermometer
2 mins
Bias
- Bias is a personal or social perspective
- Bias affects the way people view a situation
- Examples of Bias
- Conflict of interest or funding bias
- Personal Prejudices
- Strong opinions about the hypothesis
- Surprised by findings

Hybrid Punnett Square
- Gregor Mendel
- Two Hybrid Parents Mate
- 3 children have the same phenotype
- 1 child has a different phenotype
1 min
Heredity
- Passing characteristics from parent to offspring
- Those characteristics can be similar to or different from parents
- Half of the genes come from the father
- Half of the genes come from mother
- Recessive characteristics not expressed in either parent can be expressed in a child
- Some phenotypes are more favorable than others in Natural Selection
2 mins
Genotype vs. Phenotype
- Genotype is the genetic makeup
- Genotype is coded in DNA
- Genotype is shown as 2 letters that represent 2 alleles
- Genotype is the code for phenotype
- Phenotype is physical appearance of organism
1 min
Homozygous vs. Heterozygous
- Description of Genotypes
- Homozygous has 2 of the same allele (AA or aa)
- Homozygous dominant is AA
- Homozygous Recessive is aa
- Heterozygous has 2 different alleles (Aa)
2 mins
Dominant vs. Recessive
- Dominant allele dominates over recessive allele
- If both alleles are present the dominant phenotype is expressed
- The recessive phenotype is expressed only with two recessive alleles
- Examples of dominant characteristics are widow's peak, dark hair, and dark eyes
- Examples of recessive characteristics are straight hairline, light hair, and light eyes

Observation and Inference - Blue Hair
- Observations are gathered with the 5 senses
- Observations can be qualitative
- Observations can be quantitative
- Inferences are an explanation for an observation
- Based on previous experiences
- Can vary from person to person
- Can change once more information is gathered
2 mins
Observation and Inference - Green Egg
- Observations are gathered with 5 senses
- Observations can be qualitative
- Observations can be quantitive
- Inferences are an explanation for an observation
- Based on previous experiences
- Can vary from person to person
- Can change once more information is gathered
2 mins
Observation and Inference - Green Stalk
- Observations are gathered with the 5 senses
- Observations can be qualitative
- Observations can be quantitative
- Inferences are an explanation for an observation
- Based on previous experiences
- Can vary from person to person
- Can change once more information is gathered
2 mins
Question and Hypothesis - Height
- Question: Does the independent variable effect the dependent variable
- Hypothesis: Proposed explanation for how the independent variable effects the dependent variable
- Hypothesis must be testable
1 min
Question and Hypothesis - Distance
- Question: Does the independent variable effect the dependent variable?
- Hypothesis: Proposed explanation for how the independent affects the dependent variable
- The hypothesis must be testable
2 mins
Question and Hypothesis - Heat
- Question: Does the independent variable effect the dependent variable?
- Hypothesis: Proposed explanation for how the independent variable effects the dependent variable
- The hypothesis must be testable
2 mins
Validity vs. Reliability
- A valid experiment tests the hypothesis, but may not be reliable
- A reliable experiment is repeatable with consistent results, but may not be valid
- Some experiments are neither valid nor reliable
- An experiment should be valid and reliable for the conclusion to be trustworthy
2 mins
Experimental Group vs. Control Group
- Experimental Group 1 is given a treatment of independent variable
- Experimental Group 2 is given a different treatment of Independent Variable
- Both experimental groups are observed for changes
- The control group is isolated from the independent variable treatments
- Control (Constant) Variables are in each group
2 mins
Cells and the Nucleus
- Cells are the smallest unit of life
- Cells are the building blocks of all life
- The nucleus is the "brain" of the cell
- The nucleus holds DNA
