Modeling the Ocean Floor

Students made qualitative (descriptive) and quantitative (measurement) observations and sketched the particle arrangement for "dough" ingredients.

They added fractions to double the recipe, then followed the recipe to make dough.

Students used their dough to make models of the ocean floor.

In the video below students explain their ocean floor model.
