Remote labs enrich science and engineering education by vastly increasing the scope of experiments that students have access to in the course of their academic careers. As partners, the Center for Educational Computing Initiatives at the Massachusetts Institute of Technology and Northwestern University's Office of STEM Education Partnerships offer the following through The iLAB Network: * Gives science teachers and learners in traditional and online high schools, museums, and informal science education programs the ability to experience the excitement and authenticity of using high-end equipment to investigate the world in the same way that scientists do * Provides new research and learning opportunities for students, allowing them to share and discuss procedures and results * Prepares teachers to integrate iLABs in a range of science courses (including AP courses), encouraging them to go beyond the current paradigm of cookbook science labs with outdated or inappropriate equipment * Allows access by students and other audiences around the world who might not other wise have the resources to purchase and operate costly or delicate lab equipment. http://www.merlot.org/merlot/viewMaterial.htm?id=403853 A simple classroom lab which uses the enzyme Lactase to demonstrate the specificity of enzymes to a substrate (in this case, Lactose). Also, demonstrates how heat can denature enzymes. Glucose test strips are used to test for the presence of this sugar in milk, and a simple sugar solution, before and after lactase has been added. http://www.merlot.org/merlot/viewMaterial.htm?id=706238 An activity that allows students to explore serendipity discoveries http://www.merlot.org/merlot/viewMaterial.htm?id=642473 Interactive Lesson on Charles's Law http://www.merlot.org/merlot/viewMaterial.htm?id=488474 This is a lab that involves creating custom "Lava Lites.״ There is also some background information on Lava lites as well. Suitable for the middle school age group. http://www.merlot.org/merlot/viewMaterial.htm?id=708299 Documento que informa el impacto ambiental entregado por los fertilizantes y pesticidas. http://www.merlot.org/merlot/viewMaterial.htm?id=412703 This is a website that has created worksheets to companion science movies and series such as Bill Nye, Nova, and Eyewitness video. http://www.merlot.org/merlot/viewMaterial.htm?id=548038 This lesson plan is about converting mass to moles. The teacher should make a video or a photostory of a demonstration converting an amount of a substance in grams to moles. For an assessment and an opportunity for students to collaborate the teacher should set up a Google Doc with a couple example conversion problems. http://www.merlot.org/merlot/viewMaterial.htm?id=515552 במשימה זו יחקרו התלמידים את אחד היסודות מתוך הטבלה המחזורית ע״פ קריטריונים. העבודה התבצעה במקור בבלוג שיתופי התלמיד הרצה אודות היסוד אותו הוא חקר בפני הכיתה. התבצעה הערכת עמיתים באמצעות טופס מחוון מקוון. מופיע במדור פעילויות מתוקשבות של פרוייקט כתו״ם. http://www.merlot.org/merlot/viewMaterial.htm?id=515389 הפעילות מיועדת לסיכום וחזרה על המושגים שנלמדו בנושא תכונות החומרים תוך שימוש באתר קל וחומר. התלמידים מפתחים תשבצים מתוקשבים אותם פותרים עמיתים. מופיע במדור פעילויות מתוקשבות של פרוייקט כתו״ם.
