In this activity, students construct adding slide rules, scaled with linear calibrations like ordinary rulers. Students learn to move these scales relative to each other in ways that add and subtract distances, thus calculating sums and differences.... (View More) This is Activity A1 in the "Far Out Math" educator's guide. Lessons within the guide include activities in which students measure, compare quantities as orders of magnitude, use 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, the GLAST mission was renamed Fermi, for the physicist Enrico Fermi. (View Less)
This activity focuses on the question, What do active galaxies look like when viewed from different distances? Students work in small groups to learn about the small angle formula, construct a template, and use it to correctly measure the angular... (View More) size of a person. Students then use the Active Galaxies Poster to measure the angular size of a galaxy. Materials are commonly available or inexpensive items, e.g., scissors, cardboard, construction paper, calculator, protractor, meter stick or measuring tape). Includes background information, glossary, essential questions, extension activities, transfer activities, adaptations for visually-impaired students, and an answer key. This is activity 2 of 3 in the Active Galaxies Educators Guide. (View Less)
Students create a physical model illustrating soil water balance using drinking glasses to represent the soil column, and explain how the model can be used to interpret data and form predictions. Using data from the GLOBE Data Server, they calculate... (View More) the potential evapotranspiration, average monthly temperatures and precipitation for their model. This is a learning activity associated with the GLOBE hydrology investigations and is supported by the Hydrology chapter of the GLOBE Teacher's Guide. (View Less)
Materials Cost: $1 - $5 per group of students
This resource introduces the concept of wind chill, the formula used to measure it and relates it to the causes of hypothermia. A simple experiment using a pie pan, sand, fan and a thermometer demonstrates this concept. The resource is from PUMAS -... (View More) 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.

Learners will measure temperature of two different surfaces; sand and stone; on a sunny day, make a series of temperature measurements, and plot the results. Extensions include experimenting with different materials, using temperature sensors and... (View More) noncontact infrared thermometers. The activity is analogous with remote sensing of thermal properties in the Saturn system measured by Cassini. (View Less)

This activity is about the discovery of water ice on Mars. Learners will record and graph temperature data and use a model of an ice-rich and ice-free surface on Mars to examine how ice content in the martian soil would impact the temperature of a... (View More) Mars microbe after impact. A student information sheet introducing the subject of ice and the search for water on Mars is provided. The activity requires access to a freezer the night before the activity. Note: Find the latest information and updates on Mars missions at the NASA Mars Exploration website (see Related & Supplemental Resources to the right). (View Less)
This is a brief activity about the mathematics of Mars. By playing this matching card game, learners will gain knowledge of Mars mathematical facts and vocabulary. Note: Find the latest information and updates on Mars missions at the NASA Mars... (View More) Exploration website (see Related & Supplemental Resources to the right). (View Less)
In this inquiry investigation, students explore how light hits things of different shape and form. One real world application to this activity is understanding what we actually observe when we see a solar eclipse. Supplies needed for this lesson... (View More) include solid wooden geometric shapes, overhead projector, flashlights, paper, pencils. This investigation is from "Everyday Classroom Tools," a series of lessons focusing on the changing seasons and other aspects of our everyday existence. Each lesson contains information on cognitive development, an introductory inquiry activity, and an inquiry investigation. An introduction to inquiry in education and related educational resources (especially connections to folklore) are provided for educators. Differentiation is provided for K-2, grades 2-4 and grades 4-6. (View Less)
In this inquiry investigation, students conclude that the motion of the Earth is linked to the changes we observe such as the length of the day. Students learn about the reason behind the Earth's time zones. An optional water clock and sand clock... (View More) making activity supports this investigation.

This inquiry activity supports student understanding of the cause of light, heat and shadow, how to measure the passage of time, and how to use rules and other measuring tools. Students make observations using shadows, a meter stick, and a homemade... (View More) sundial.
