In this experiential activity, students demonstrate to themselves the effect of the optic disc, or blind spot, inherent to the optic nerve entering the posterior of the eye (bulbus oculi). This resource is from PUMAS - Practical Uses of Math and... (View More) Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications. (View Less)

This interactive, online module allows learners to study the history of the discovery of black holes. Learners may work independently or in small groups to complete the activity. By completing this activity students learn the history of the... (View More) discovery of black holes. This activity is a subsection of the "Is a Black Hole Really A Hole?" within the online exploration "No Escape: The Truth about Black Holes." Detailed teacher pages, identified as Teaching Tips on the title page of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards.

This resource explains how to estimate the global consequence of a person's actions to quantify what it is to "think globally." To lend meaning to the result, it introduces "order-of-magnitude" thinking. Three examples, on the global impact of a... (View More) short drive, a little water and an hour of light, are described.

Scientists use estimates as a check on more precise measurements; estimation is an easy way to quantify early hypotheses that can be tested or checked later in formal analysis. This article describes a number of examples of the use of estimating the... (View More) answers.

This is a poster about Europa. Learners may read informational text or complete the Europa Geology Jigsaw Puzzle to learn about creating a geologic map of the ice on this moon of Jupiter.

This article contains a series of kinesthetic activities, explaining and demonstrating why stars twinkle and what astronomers can do to minimize it. The activities can be used to demonstrate how Earth's atmosphere distorts starlight and how advanced... (View More) telescope technology (adaptive optics) is used to compensate for this distortion.

In the state of Maryland, a local politician once claimed that sea level is rising because there are too many people putting boats on the open ocean. Could that result in a significant sea level rise, perhaps even destroy low-lying nations such as... (View More) Bangladesh? This resource explores the principle of buoyancy, and is part of PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.
