Supplied materials

  • All measurements and observations below are supplied classroom examples. They are not data from actual learners or a claim about a particular real site.
  • Paper, drawing space or a browser document.
  • Reference card A: linked to parental biological information. Reference card B: linked to supplied growing conditions.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Fur pattern linked to parent records.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Same variety shorter with limited water.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Animal learns a route after practice.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Two plants differ but no background is given.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Supplied gene information affects flower color.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Training changes a response.

Learn the idea

Inherited information comes from parents. Environmental conditions can influence how a trait develops. Learning also changes behavior. Our fictional organism records identify the specific influence.

Inherited means linked to parental biological information. Environmental means linked to supplied growing conditions. Learned means developed through practice in this record. Unresolved means evidence does not distinguish influences.

For inherited, look for the clue “linked to parental biological information.” For environmental, look for “linked to supplied growing conditions.” More than one process can happen in a real situation. Answer about the one described in this question.

  1. Read or listen to the four science words and what each means. Say how the first two differ.
  2. Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
  3. Answer each practice question. Say which clue helped you, then check the explanation.
  4. Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.
Worked example

See the method in action

Worked reference-card problem: a card states “linked to parental biological information”; a second states “linked to supplied growing conditions.” The first fits inherited and the second fits environmental. The reason is the described function or change, not the order of the cards or a favorite name. If their descriptions exchange places, their category labels exchange too. Keep the supplied descriptions attached to the correct case.

Helpful tips
  • Use the feature “linked to parental biological information” to justify inherited; do not sort by the name alone.
  • Distinguish environmental (linked to supplied growing conditions) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: Fur pattern linked to parent records.

inherited

The answer is inherited. In the notes, it means “linked to parental biological information.” Inherited information comes from parents. Environmental conditions can influence how a trait develops. Learning also changes behavior. Our fictional organism records identify the specific influence.

Take it further

Create one new case showing inherited and one showing environmental. Expected: the first explicitly shows “linked to parental biological information”; the second explicitly shows “linked to supplied growing conditions.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.

More practice: try new cases

Choose an answer for each problem. Explain your method on paper, then use the feedback to decide what to revisit.

More practice: try new cases
1. Which scientific label fits the specifically described step or feature? Supplied case: Same variety shorter with limited water.
Need a hint?
  • Look for the described feature: linked to supplied growing conditions.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
2. Which scientific label fits the specifically described step or feature? Supplied case: Animal learns a route after practice.
Need a hint?
  • Look for the described feature: developed through practice in this record.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
