Modeling > GradeS 1 and 2

In grades K–2, students begin to build simple models (drawings or physical replicas) to represent objects or phenomena they study in class. They describe in what ways the model is a good representation, and they should be encouraged to explain the difference between the model and and the actual object or phenomenon it represents. Where appropriate, they can also use digital models that closely tie to the work they did within the unit.

Grade 1 Science: Light and Shadows

Students explore how light creates shadows.

• They experiment with making shadows outside with the sun and inside using a flashlight.
• They sketch their experiments, annotating them to create a model of how the light source casts a shadow.
• They repeat their experiment using a graphic web-based model that replicates some of the experiments they did before, but adds additional elements (such as moonlight).

Grade 2 Science: The Effects of Wind and Water Movement on Earth's Landscape

Students investigate how blowing wind and flowing water can move earth materials and change the shape of landforms.

• Students explore various physical models of landscapes.
• Students simulate weather phenomena, such as wind and rain, on their landscapes.
• Teachers reinforce what a model is, and how it represents only a part of the actual phenomenon they’re studying.
