The book titled Exploring Laboratory Experiments in Chemistry Through Pre-lab and Post-lab Activities covers the standard experiments in Physical, Inorganic, Organic and Analytical chemistry, from the undergraduate chemistry laboratory curriculum. Use of pre-lab and post-lab approach in the proposed book would make it different from the routine laboratory manual. Efforts have been made to highlight safety and waste disposal of chemicals. A section on conceptualizing mini projects of 2-3 lab sessions in UG chemistry laboratory settings has also been included. This should help the students to get hands-on experience of the inquiry-based approach to perform experiments. The editors strongly feel that the experimental tasks in the book with pre-lab and post-lab questions and the section on mini projects will be the USP of the book and it would be the first of its kind in the Indian context.

I know this iff off topic but I’m looking into starting my own blog and
was wondering what all is needed to get setup? I’m assuming having a blog like yours
would cost a pretty penny? I’m not very web savvy so I’m nott
100% certain. Any suggestions or advice would be greatly
appreciated. Thanks https://www.horseracingnation.com/user/Shosine

I’ve been surfing online greater than 3 hours these days, yet I never found any attention-grabbing article like
yours. It is lovely value sufficient ffor me. In my opinion, if all site owners and bloggers made god content
as youu did, the net will be a lot more helpful than ever
before. https://linktr.ee/aviatorsgames
