"Apples to Atoms" is a collection of activities focused on important concepts underlying nanoscience, developed for middle school science and math students. Each of the four chapters (Size and Scale, Measurement, Microscopy, and Surface Area to Volume Ratios) contains a series of linked activities, and readings which provide context for the concepts developed in the activities. Suggested assessment items are also included. The chapters are inter-related, but are designed so they may be taught independently or in any order.

Students investigate the weather from a systems approach, learning how individual parts of a system work together to create a final product. Students learn how a barometer works to measure the Earth's air pressure by building a model out of simple materials. Students analyze the changes in barometer measurements over time and compare those to actual weather conditions. They learn how to use a barometer to understand air pressure and to predict actual weather changes.

This task was developed by high school and postsecondary mathematics and design/pre-construction educators, and validated by content experts in the Common Core State Standards in mathematics and the National Career Clusters Knowledge & Skills Statements. It was developed with the purpose of demonstrating how the Common Core and CTE Knowledge & Skills Statements can be integrated into classroom learning – and to provide classroom teachers with a truly authentic task for either mathematics or CTE courses.

Follow Mary Jane and Eliza as they test and measure the best way to use a moving ball's energy to win at carnival games in this video from DragonflyTV.
Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed if off just the smallest bit. Many of the measurements made while navigating involve angles, and a small error in the angle can translate to a much larger error in position when traveling long distances.

Describes how economic theory is linked to economic evaluation techniques like cost-benefit and cost-effectiveness analysis and to introduce students to many concepts that are specific to economic evaluation. Introduces students to the many varieties of economic evaluation to establish a common terminology. Discusses cost-benefit with a demonstration of how this type of evaluation is most clearly linked to economic theory. Explores other theories and concepts, including cost measurement, benefit valuation, and incremental decision-making. Finally, explores recommendations on performing economic evaluations that are made in the United States with a focus on how these are related to underlying economic theory and other concepts.
This publication offers online resources that connect mathematics to three subject areas: social studies, art, and science. Each section contains lesson plans, problems to solve, and examples of mathematics at work within contexts not usually associated with school mathematics.

This educator's guide was developed with the Cosmic Questions national traveling exhibit. It contains activities relating to the exhibit's theme, our place in space and time-and information about the exhibit. Although the guide complements a museum visit, activities can be used independently from the exhibit.
Data Tool is a data analysis tool for plotting and fitting data from laboratory experiments, simulations, video analysis, or any other data set organized into columns. A click of a checkbox in Data Tool allows the user to change the appearance of plots, see standard statistics for the data set or apply built-in linear, quadratic or cubic fits to the data set. Data Tool also includes a number of standard mathematical functions that can be applied to the data set, allowing for further analysis and extending the range of potential fits to the data.
In this experiment, students measure the area of a dime using methods similar to those used by scientists to measure the size of atoms. When working with atoms, scientists sometimes have to invent new ways of doing simple things. For instance, scientists can't use a ruler to measure the size of an atom's nucleus. This activity shows how ratios can be used to calculate the area covered by an object.
Students investigate the difference between qualitative and quantitative measurements and observations. By describing objects both qualitatively and quantitatively, students learn that both types of information are required for complete descriptions. Students discuss various the characteristics of many objects, demonstrating how engineers use both qualitative and quantitative information in product design.
