Big vs. Little - Macro to Micro Lesson 5
It is a long way from nano to macro. Learners examined the scale of measurement from macro to nano in the first four lessons of the five-part series. With the final installment, they review what they learned by classifying objects in one...
Curated OER
Soil Soakers
Students work together to discover the relationship between water holding and drainage characteristics of soils. They record their observations and discuss the results. They examine particle size and pore sizes as well.
Curated OER
Lesson Nine: Size and Scale
Learners investigate scale as it is related to maps. In this map lesson, students read Jack and the Beanstalk by Carol North. Learners then compare the setting in the story to a landscape picture map to help them study scale.
