This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships. This activity demonstrates three search methods for finding information in data: linear searching, binary searching and hashing. It also includes an optional introductory activity as well as a video showing a fun demonstration related to the same content.
Scientists who are working to discover new medicines often use robots to prepare samples of cells, allowing them to test chemicals to identify those that might be used to treat diseases. Students will meet a scientist who works to identify new medicines. She created free software that ''looks'' at images of cells and determines which images show cells that have responded to the potential medicines. Students will learn about how this technology is currently enabling research to identify new antibiotics to treat tuberculosis. Students will complete hands-on activities that demonstrate how new medicines can be discovered using robots and computer software, starring the student as ''the computer.'' In the process, the students learn about experimental design, including positive and negative controls.
10 Lesson mini-maker camp for introductory programming and circuitry on the Raspberry Pi. Students are introduced to basic program structures (while loops, if/elif/else statements) and taught to wire LEDs and sensors then given extensive work time to create a project authentic to their lives that uses their new skills.
The Mangrove Mapping Curricula strives to provide opportunities for students to learn about and explore mangroves and their ecosystems. Through this process it is hoped that students develop and understanding and appreciation for mangroves and the role they play in a healthy environment. Mangroves are group of tropical/subtropical trees that live in salt or sweet (salt/fresh water combination) water coastal environments. They are considered a cornerstone species and play important roles in habitat formation and stabilization of coastal environments.
This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution. Groups of learners (at least 10) repeat a secret message (five to seven similar-sounding words) like the game "Telephone". In this version of the game, however, learners write and then code what they hear, creating a model of a phylogenetic tree and using a species distance matrix. This resource includes background information about phylogenetic trees, maximum parsimony, and matrix theory (see page 6-7 of PDF).
Wireless Networking in the Developing World is a free book about designing, implementing, and maintaining low-cost wireless networks.
This book is a practical guide to designing and building wireless networks in local communities, enhancing lives through improved communication, access to information for educational, social and economic growth. Its primary goal is to help expand access to the Internet and to expand the deployment of community networks where there is currently no infrastructure to enable this to happen. Written by subject matter experts who have vast experience in deploying wireless networks in the field and connecting communities to the global Internet.
You can find the latest edition of the Wireless Networking in the Developing World available on-screen and for download.
