71+10 New Science Projects (With Online Content on Dropbox)

Do you have a project-assignment fron your physics teacher and do not know where to begin? Or you have to participate in a Science Fairand you wish to surprise everyone with a revolutionary chemistry model? Or you simply wish to experiment with new concepts of physicselectronicsbiology and chemistry? This revised book and the free CD contains 71+10 new projects on Physics Chemistry Biology and Electronics. The purpose of the book and CD is to ensure simple explanations of these 81 Science Projects done by Secondary and Senior Secondary students. This book will be a useful guide in the preparation of project work for students participating in science exhibitions. At the end the book features many additional projects to work upon. Highlights: *Making an automatic Electric Alarm. *Making a Railway Signal. *Making an Astronomical Telescope. *Producing electricity from potatoes. *Making the Morse Code. #v&spublishers Contents: 1.
