Hide and Seek with Bones: A Mapping and Scaling Comparison

How do oceanographers make maps under water? Junior explorers discover the technologies and processes involved in creating bathymetric maps in part three of a five-part series designed for fifth- and sixth-grade pupils. The lesson...

Extremely large or extremely small numbers are difficult to comprehend. To help understand the massive scale of the solar system, learners complete two activities. First, they create a model to compares the size of the bodies in the...

Practicing paleontologists map the geologic time scale, simulate the formation of sedimentary rock, and analyze fossil data. Instructions for four activities and five assessment choices are provided for the teacher. This comprehensive...

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Here is an excellent cross-curricular lesson. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...

Students read and use topographical maps. They also use a compass to find bearing to an object on a map and in the classroom. Ask your students how they might travel to somewhere they have never been to befo

Third and fourth graders are introduced to the concept of map scale. Using an illustration, they discuss if it shows the actual size of the object and why scale is used to represent areas. They use some items in the illustration to...

Maps are designed to allow people to travel to a new location without a guide to show the way. They tell us information about areas to which we may or may not have ever been. There are many types of maps available for both recreational...

Learners consider the comparative sizes of the planets in the solar system. In this scale lesson, students select balls of different sizes to represent the planets in the solar system.
