This lesson incorporates sea surface data collected by NASA satellites. Data for three surface characteristics- height, temperature and speed- are used for several activities. Students examine the differences in speed of currents relative to distance from the Equator. Sea surface data anomalies are charted and further analyzed. In addition, surface current data is presented to examine patterns related to El Niño. Note that this is lesson three of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website that provide science background information, data resources, teacher material, student guides and a lesson matrix.
Students learn about and practice converting between fractions, decimals and percentages. Using …
Students learn about and practice converting between fractions, decimals and percentages. Using a LEGO® MINDSTORMS® NXT robot and a touch sensor, each group inputs a fraction of its choosing. Team members convert this same fraction into a decimal, and then a percentage via hand calculations, and double check their work using the NXT robot. Then they observe the robot moving forward and record that distance. Students learn that the distance moved is a fraction of the full distance, based on the fraction that they input, so if they input ½, the robot moves half of the original distance. From this, students work backwards to compute the full distance. Groups then compete in a game in which they are challenged to move the robot as close as possible to a target distance by inputting a fraction into the NXT bot.

Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. 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 acquire a basic understanding of the science and engineering of space travel as well as a brief history of space exploration. They learn about the scientists and engineers who made space travel possible and briefly examine some famous space missions. Finally, they learn the basics of rocket science (Newton's third law of motion), the main components of rockets and the U.S. space shuttle, and how engineers are involved in creating and launching spacecraft.

Students learn about ultraviolet light in this Moveable Museum unit, where they detect UV rays and then explore ways to block them. The four-page PDF guide includes suggested general background readings for educators, activity notes, step-by-step directions, and information about where to obtain supplies. Students make a bracelet from beads that respond to UV light by changing color, and test it in different light environments.
The Developmental and Reproductive Toxicology and Environmental Teratology Information Center (DART/ ETIC) …
The Developmental and Reproductive Toxicology and Environmental Teratology Information Center (DART/ ETIC) Database is made available by the National Library of Medicine's Toxicology Data Network. The database contains over 100,000 current and earlier literature citations covering teratology and other aspects of developmental and reproductive toxicology. Users may search the database by subject, title words, chemical name, Chemical Abstracts Service Registry Number, and author. The Web site also includes a useful help page and sample record for familiarizing oneself with the database.

The lesson plan, designed for 9th-grade students, focuses on digital citizenship, encompassing online safety, cyberbullying, privacy settings, and phishing. Students learn the importance of responsible digital behavior and practical strategies for staying safe online. They explore the types and impact of cyberbullying, understand the significance of privacy settings, and discover how to protect themselves against phishing attempts. The lesson concludes with students creating personal digital citizenship pledges to guide their online interactions, emphasizing responsible and ethical behavior in the digital world.

This course, Digital ESL, offers a simple, guided path to digital literacy starting with foundation skills training for those less proficient in English. It was designed to maximize hands-on learning opportunities both in and outside the classroom, utilizing students' own smartphone devices. Although originally designed for teaching older adult (age 65+) beginner learners of English, it can be used for teaching common smartphone features to adults of any age!

For most of human history, recording a star meant describing it with words or drawing a picture. The 19th-century invention of photography changed that—only to be revolutionized by digital imaging. This Moveable Museum article, available as a six-page printable PDF file, takes a look at the technology of digital imaging. It discusses how digital images are pictures stored as numbers and explains how computer manipulation can enhance images and reduce distortion. Some suggested resources are provided for further research.

Students discover the mathematical constant phi, the golden ratio, through hands-on activities. They measure dimensions of "natural objects"—a star, a nautilus shell and human hand bones—and calculate ratios of the measured values, which are close to phi. Then students learn a basic definition of a mathematical sequence, specifically the Fibonacci sequence. By taking ratios of successive terms of the sequence, they find numbers close to phi. They solve a squares puzzle that creates an approximate Fibonacci spiral. Finally, the instructor demonstrates the rule of the Fibonacci sequence via a LEGO® MINDSTORMS® NXT robot equipped with a pen. The robot (already created as part of the companion activity, The Fibonacci Sequence & Robots) draws a Fibonacci spiral that is similar to the nautilus shape.
