This is a simple lab, but it has a lot of parts to it, like measuring the outside of your Science building. You might have to alter that part of the assignment to fit your needs. You will also need to copy and paste a map of your school grounds for the last section of the lab. It's a good lab that also involves doing conversions between the different measurements: decimeters to millimeters, etc. Take a look at my PowerPoint on using the Metric Ruler and Meter Stick to help with this lab. 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.
