a simple, active, declarative sentence containing no modifiers or connectives that may be used in making more elaborate sentences.
A sentence kernel is not a sentence fragment.
E.g. NOT a kernel
They seem.
She enjoys.
John
E.g. Is a kernel
Germany surrendered.
Picasso painted.
America rejoiced.
To expand a kernel, students should be provided with question words, in this order
Who
What
When
Where
Why
How
Using just 2 or 3 questions words is sufficient for a sentence kernel to be expanded.

Example
Water boils
What: The boiling point of water is 100 C
When: The boiling point of water depends on the atmospheric pressure, which changes according to elevation

When heated to 100 degrees Celsius, water bubbles and turns into vapour, although at different altitudes the temperature required to make this happen can vary.
