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 magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic fields in nature. This activity requires use of a galvanometer, bar or cow magnet, and wire. This is the fifth lesson in the second session of the Exploring Magnetism teacher guide.
Today, we'll explore the materials electrical engineers work with. We'll look at high-conductors, insulators, and how low-conductivity conductors can be used to generate light and heat.
The study of electricity goes all the way back to antiquity. But, by the time electricity started to become more well known, a few familiar names started to appear. Edison, Galvani, and a few others really changed the way the world worked.
This is an algebra-based introductory course for electricity physics. It is intended to be a comprehensive introductory course in all electricity aspects.
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.
In this activity, students construct an analytical spectroscope and analyze the spectrum produced when various substances are heated or excited with electricity. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.
In this activity, students study the range of colors in a visible light spectrum created from either a glass prism or holographic diffraction grating. This activity is in unit 2 of the "Space-Based Astronomy" guide that contains background information, worksheets, assessment activities, extensions, and alignment to national education standards.
In this activity, a Whiffleå¨ ball containing a battery-operated buzzer is twirled in a circle to demonstrate the Doppler effect.åÊ The demonstration is an illustration of how stellar spectra can be used to measure a star's motion relative to Earth along the line of sight. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.
Using a paper and tape device, students experience how atoms and molecules of gas in Earth‰Ûªs atmosphere absorb electromagnetic energy through resonance. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.
In this activity, students demonstrate the relationship between wave frequency and energy in the electromagnetic spectrum by shaking a rope to identify the relationships. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.
This is an activity about the properties of electromagnets, which is a crucial underpinning for understanding how magnetic fields are generated in nature, in the surface of the Sun, and in the interior of Earth. Learners will create an electromagnet by letting an electric current flow through a wire to generate a magnetic field, which is then detected using a compass. This activity requires a thin insulated wire, pencil, battery, compass and paper clips. This is Activity 2 of the Magnetism and Electromagnetism teachers guide.

This is a lesson that applys occultations to Saturn's Moon Enceladus. Learners will establish whether Saturn‰Ûªs small moon, Enceladus, has an atmosphere, whether that atmosphere is over the entire planet, and what creates Saturn‰Ûªs E-ring. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.
Students learn to apply the principles and concepts associated with energy and the transfer of energy in an engineering context by designing and making musical instruments. They choose from a variety of provided supplies to make instruments capable of producing three different tones. After completing their designs, students explain the energy transfer mechanism in detail and describe how they could make their instruments better.
Demos and activities in this lesson are intended to illustrate the basic concepts of energy science -- work, force, energy, power etc. and the relationships among them. The "lecture" portion of the lesson includes many demonstrations to keep students engaged, yet has high expectations for the students to perform energy related calculations and convert units as required. A homework assignment and quiz are used to reinforce and assess these basic engineering science concepts.
Students search for clues of energy around them. They use what they find to create their own definition of energy. They also relate their energy clues to the engineering products they encounter every day.
The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process.
