Look for similarities without expecting an exact copy
Compare an original parent-and-young-plant model, support a claim with visible features, and follow a selected DC Grade 1 NGSS reference.
The DC science standards directory identifies NGSS adoption in December 2013 and links the standards publisher. Use the Publisher NGSS document for the selected performance expectations and their examples and boundaries. This activity selects a Grade 1 expectation. It is one part of a science course, not a complete curriculum.
Compare a bean plant and its young plant
The table is an invented classroom description of a parent bean plant and a young bean plant grown from one of its seeds. Treat it as a practice model. Which features are alike, and which are different? Use the observations to explain why the young plant is similar to its parent without being an exact copy.
Explain the evidence or model
Both descriptions include a green stem and leaves with the same general shape. These visible similarities support the claim that the plants are alike. The parent is taller, has larger leaves, and has flowers; the young plant is shorter and has no flowers yet. Those differences do not make the young plant a completely different kind of plant. A useful response names at least one shared feature and one difference, then connects both to the comparison.
| Feature | Parent plant | Young plant |
|---|---|---|
| Stem | Green | Green |
| Leaf shape | Oval with a pointed end | Oval with a pointed end |
| Leaf size | Larger | Smaller |
| Flowers | Present | Not present yet |
What to check in the explanation
“They are the same because both are plants” is too broad: it does not use the described features. “They cannot be related because one has no flowers” ignores the difference between a young plant and a mature plant. Do not treat the table as proof of why a particular feature differs. The descriptions support a comparison, not a genetic explanation or a claim that every young plant will look exactly like this one.
Plan the next activity
- Read the two descriptions together and identify one feature shown for both plants.
- Sort the observations into alike and different, naming the feature rather than only saying “big” or “small.”
- Help the child make an oral or drawn explanation that includes a similarity and a difference.
Observe another known parent-and-young plant pair through classroom specimens or reliable photographs. Record what can actually be seen before discussing the comparison. Ask the child whether a larger leaf is a different shape or simply a different size. Keep the explanation focused on visible patterns; detailed inheritance mechanisms are beyond this selected Grade 1 activity.

How does Grade 1 connect to DC’s science assessment?
Grade 1 is outside DC’s NGSS summative assessment grades. DC CAPE Next begins in spring 2027 and lists science assessments in Grades 5, 8, and high-school biology. OSSE says the educational standards have not changed. Resources here are independently published practice, not official state assessments or predictions of a state score. Read the official guidance.
Must a young plant look exactly like its parent?
No. A comparison can show shared features and differences. Here, the plants share stem color and general leaf shape but differ in leaf size and flowering stage.
Where should I check the complete science requirements?
Start with the DC science standards directory and the official NGSS references. Read the Grade 1 expectations and their boundaries alongside the school’s curriculum plan. The selected investigation and resources here do not certify complete course coverage. Read the official guidance.
