Step 1: Lesson Standards & Learning Goals

NC K-12 Science Supporting Document Grade 2

Dimension 1:

Science and Engineering Practice: Analyze and Interpret Data: Students use observations to describe and analyze patterns of different characteristics in offspring of the same parents (NSTA SEP Matrix).

Dimension 2:

Crosscutting Concepts: Patterns

Dimension 3:

Disciplinary Core Ideas:

LS3.B Individuals of the same kinds of plant or animal are recognizable as similar but can also vary in many ways (A Framework for K-12 Science Education).

Sample Essential Questions

How can we use data to understand the differences and similarities between offspring of the same parents?

Vocabulary

characteristics
different
organism
related
similar
variation

Students will be able to...

Compare observable characteristics of animals and their parents; how they are alike and different.
Illustrate - Finding a specific example or illustration of a concept or principle
Analyzing and Interpreting Data: Use and share pictures, drawings, and/or writings of observations of the appearance of animals and their parents.

Students will know...

Groups of organisms of the same type have similar characteristics as well as characteristics that are different.

Step 2: Assessment

Formative Assessments

Writing Prompts

What is a characteristic? Give an example. (qualities or features of a plant, animal or person; e.g., curly coat on a poodle, tiger stripes, leaf shape, etc.)
What is variation? Give an example. (differences in related organisms)
Is there variation in animals and plants that are related? (Related animals can look very similar to each other, but also have variation in their characteristics and look different.)

Mini Projects and Investigations

Handy Family Tree
Draw the Family
- Option 1: Draw your family and label how you are similar and different.
- Option 2: Draw an animal family and label how they are similar and different.
- Option 3: Draw a plant family and label how they are similar and different. (Ex. corn plant to stalk, spider plants with "babies," pine sapling and tree)

Formative Assessment Examples

Culminating Activity

Compare the sibling puppies. How are they similar and how are they different? Based on the puppies characteristics, draw an image of what you think their parents might look like.
