Mapping the Bone Field: An Area and Scale Exercise
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.

Ocean Scale Drawing
Students explain how to make pictures larger using a grid system by transferring scales images from 1/2 -1 inch to 6 inches - 1 foot. They create life-size scale drawings of ocean life studied in class using a grid system.

Gridding a Site
Students make observations of effigy mounds and record them in a notebook. In groups, they must determine the scale of measurement and create their own grid to scale part of the Effigy Mounds National Monument. They also practice using...

Are All Asteroids' Surfaces the Same Age?
Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final instructional activity of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating...

Big Fleas Have Little Fleas
A benthic habitat hosts a vast collection of organisms and its structure influences the biodiversity. Middle-school marine biology explorers will discuss how corals impact structure, and therefore diversity, on the ocean floor. They draw...

Objects Race 500
Young scholars explore the concept of "shape affects speed" through a series of experiments. In this physics lesson, students participate in an experiment in which various objects are released on an inclined plane. Speed and distance are...

Heads Up!
Students investigate fossils through reading Digging Up Dinosaurs and the study of a scale triceratops head. In this dinosaur fossil lesson plan, students students each draw a portion of a picture of a dinosaur head....

Arctic Microclimates
Learners identify, measure, and average micro-climatic temperatures in a particular region. They draw a small-scale map of an area to be sampled (classroom, playground, park, backyard) and identify potential locations for...

Are All Asteroids' Surfaces the Same Age?
There are more than 600,000 asteroids in our solar system. Pupils analyze images of two asteroids in order to determine if they are the same age. They count craters for each asteroid and compare numbers.
Curated OER
Big Fleas Have Little Fleas!
Students study seamounts and learn the importance of structures to species. For this ocean explorer lesson, students participate in an activity that teaches them how to modify a seamount so that they are more suitable for...

Necessary Nitrogen
Learners view a video that presents the biogeochemical cycle of nitrogen. They compare types of soils and consider how different fertilizers affect soil composition.
