This lesson focuses on how materials behave differently as their surface area increases.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity, learners find Xi'an, the archaeological area in China where the Terra Cotta Army was discovered, on a map or globe and look more closely at the relationship of the warrior site to ot

In this activity, learners explore the relative sizes and distances of objects in the solar system.
