Home Revise Science Experiment Lab DVD(DVD)

"Children love to experiment independently. The Concept of Science will become clear only when the students perform experiments themselves. Science Experiment Lab gives the students actual chance to perform those experiments themselves at home due to interactive experiments. Also Interactive Question & Answer format provides a better understanding of science concepts & students can remember & write the answers in Exam.Features :-1) Based on the Textual Syllabus2) Interactive Experiments3) Interactive Question & Answers4) Learner friendly Presentations5) Useful for 5th to 10th std.Benefits:1) Increases positive attitude towards science2) Increases skill proficiency3) Increases independent thinking and decision making4) Increases logic development, perception and creativity"For 8th Std.1.
