It is common in the real world to see mathematical examples where the cents sign was used when the dollar sign was supposed to be used. Converting and comparing decimals and fractions can help clear up this misconception. Two real coupons clipped from a Sunday paper coupon section are included in this activity. This resource is from 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.

One particular type of domino game, sometimes called the All Fives Domino game, uses multiples of five in order to score points. It can be the basis for a number of games designed to develop conceptual understanding of multiples of numbers through twelve and provide opportunities to reinforce learning objectives in a fun and competitive manner. This resource is from 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.

In this activity, students use the binary number system to transmit messages. Two flashlights are used to demonstrate how astronomy spacecraft to transmit images and other scientific data to Earth. This activity is part of Unit 4 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.

Students identify the actual colors of objects bathed in monochromatic light and learn how three colors of light can be combined to produce colors ranging from black to white. Students see how space observatories make use of monochromatic filters to collect data on the color of objects in space. The activity is in unit four of the "Space-Based Astronomy" guide that contains background information, worksheets, assessment activities, extensions, and alignment to national education standards.

In this activity, students simulate how light collected from a space object converts into binary data and reconverts into an image of the object. A pencil and paper activity demonstrates how astronomical spacecraft and computers create images of objects in space. This activity is part of Unit 4 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.

This math problem demonstrates the concept of geometric progression, through an example of a million dollar contract between an employee and an employer. Application of the concept of geometric progression to social cause activism is addressed. This resource is from 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.

This movie provides an 18-minute introduction to how NASA is observing our ever-changing planet. On the The Dynamic Earth DVD Web page you can download the video as an iPod or iPhone version, as well as an AppleTV/Full resolution version, and access a glossary and links to related Web sites.

This is an activity about planetary sizes and distances. Learners will construct a scale model of the Earth, Earth’s Moon and Mars in relation to each other using balloons. They will use this model to predict distances and reflect on how scientists use models to construct explanations through the scientific process. The lesson models scientific inquiry using the 5E instructional model and includes teacher notesand vocabulary.

This is a wallsheet that contains 11 activities relating to Mars. Learners could investigate: how far away is Mars, why does Mars have craters, water on Mars, Mars' minerals, how high the mountains are on Mars, and are invited to create a martian calendar and travel guide.

In this demonstration, evidence of the Earth's rotation is observed. A tripod, swiveling desk chair, fishing line and pendulum bob (e.g., fishing weight or plumb bob) are required for the demonstration. This resource is from 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.

This is an activity about the relative sizes of the Earth and the Moon and the distance between them. Learners will inflate a balloon to the approximate size of the moon in relation to a standard globe. They will then hypothesize as to the correct distance between the two and begin to calculate angular size. This is Astronomy Activity 1 in a larger resource, Space Update.

This is a children's science story about gravity (title translated: The World of Copocuqu: Queen Gravity and King Mass). Learners will read about the force of gravity and how it relates to the mass of a body. The story takes place in an asteroid in which all its inhabitants talk in the form of questions or the world of Copoqucu. The story ends with a magic secret (or learning capsule), which reflects in synopsis the science message that the child would take with him or her.

This is an activity about electromagnetism and the Sun. First, learners will do a KWL activity using six vocabulary words. Next, they will build an electromagnet and investigate how it works. Finally, learners will relate the workings of their electromagnet to a Solar Dynamics Observatory magnetogram image of the Sun. Per group of learners, this activity requires materials such as a length of insulated wire, alligator clips, a 2-D-battery holder, two D-batteries, and a nail.

This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion exchange, discuss and research the "softness" and "hardness" of water, and use the periodic table to identify elements and learn their characteristics. Background information, a glossary and more is included. Materials needed for each student group include a 9-volt battery, two electrodes (e.g. copper strips, or two #2 pencils sharpened at both ends), electrical wire and glass beakers or ceramic saucers. This activity is part of the Aquarius Hands-on Laboratory Activities.
