This lab introduces the procedures for using a Triple Beam Balance. It's a good lab that covers the three different ways of finding the mass of a substance. It also contains Analysis and Conclusion questions at the end of the lab. Take a look at my PowerPoint on how to use and read a Triple Beam Balance. It will help out a lot!! This activity supports Grade Seven California State Science Standard 7A - Select and use appropriate tools and technology (including calculators, computers, balances, spring scales, microscopes, and binoculars) to perform tests, collect data, and display data.
