Science/Strand III
Content Standard 3
All students will investigate and explain how characteristics of living things are passed on through generations; explain why organisms within a species are different from one another; and explain how new traits can be established by changing or manipulating genes. (Heredity)

Science/Strand III/Content Standard 3/Elementary
Benchmark 1
Give evidence that characteristics are passed from parents to young.

Benchmark Clarification

All living things pass on characteristics to their offspring. Common physical characteristics can be used to match the offspring of an organism with its parent. Students will:

  • Identify that a puppy looks like a dog
  • Identify that a kitten looks like a cat
  • Identify that saplings look like trees
  • Identify that seedlings look like plants

Instructional Example

Benchmark Question: What characteristics of living things are passed on through generations?

Focus Question: What physical characteristics are shared between a young living thing and its parent?

Students will each select a plant or animal (encourage no repeats!). Each child then will obtain two pictures of that plant or animal, one as an immature organism and one as a mature organism. Pictures can be provided by the teacher or found on the computer. Students then will mount the pictures on two 3 x 5 cards. The teacher then will divide the class into small groups. Each member will put his or her two picture cards face down on a desk, mixed with the other membersŐ cards. In turn, students will flip one card over and attempt to find its mate. If no match is found after a child has turned up two cards, both cards are turned back over and play progresses to the next student. A student making a match must explain the shared characteristics to keep the matched cards. Play ends when all matches have been made.

Constructing: (SCI.I.1.E.1), (SCI.I.1.E.2), (SCI.I.1.E.5).

Reflecting: (SCI.II.1.E.1), (SCI.II.1.E.3), (SCI.II.1.E.5).

Assessment Example

Students may use one set of the parent/offspring picture cards created for the Instructional Example (SCI.III.3.E.1) or brainstorm a set of parent/offspring organisms to create a Venn diagram. The diagram will illustrate the similarities and differences of the organism pictured on the cards or brainstormed.

(Give students rubric before activity.)
