This simple exercise demonstrates how Maya numbers are written and how higher place values of numbers are calculated. This activity can also be used in informal education settings with people ages 9 through adult. Includes information for educators,... (View More) Maya numbers and place values chart, and worksheet. Common Core State Standards for Math are identified. (View Less)
In this lesson plan students use temperature data to look at the measures of central tendency. By using mean, median, and mode, students will gain a better understanding about weather patterns from several locales throughout Virginia.
In this activity, students estimate the size of the visible universe in relation to the size of the Milky Way Galaxy. To do so, students will get a sense of scale and will convert from centimeters to kilometers. This is activity one in the "Hidden... (View More) Lives of Galaxies" information and activity booklet that was designed for use with "The Hidden Lives of Galaxies" poster. The booklet includes student worksheets and background information for the teacher. (View Less)
This interactive, online module allows students to discover the velocity needed to escape the Earth's gravitational pull. By completing this activity, students discover how mathematics can be used to find escape velocity. Students may complete this... (View More) activity independently or in small groups. Detailed teacher pages, identified as Teaching Tips on the title page, provide science background information, lesson plan ideas, related resources, and alignment with national education standards. This module is a subsection of "Is a Black Hole Really A Hole?". It is within the online exploration No Escape: The Truth about Black Holes available on the Amazing Space website. (View Less)
In this activity students use their Log Tapes as a reference for ordered pairs, and graph positive numbers as a function of their base-10 logarithms. They extend each plotted point to the vertical axis, thereby generating a logarithmic scale that... (View More) cuts and folds into an improvised slide rule. This is activity E1 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure,compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

This is an activity about the magnetic deflection. Learners will observe and measure the deflection that an iron mass causes in a soda bottle magnetometer and plot the data. The data should show the inverse-square cube law of change in the magnetic... (View More) field. This is the twelfth activity in the guide and requires prior use and construction of a soda bottle magnetometer, as well as a six to ten pound container of iron nails (or an equivalent iron mass).
