Hi (especially for my Grade X students),
Here I give you link in Scribd to open and download Chapter 1 note, about Instruments and Measurement (in case you've lost your hard copy).
Besides that, I also give link for you to open or download the exercise I've given to you before quizzes. This is the link:
You can review and try to do it again at home.
Below are also links for you to download vernier calipers and micrometer applets. The website itself has so many useful things for studying physics. By the way, you have to register first before you do the downloading.
