TOPS science question

[sdobis]

I would like to move away from science demonstrations to actual science experiments. I want there to be constants and variables. I want there to be scientific measurements. I want the scientific method. Would TOPS meet this requirement?

 

Any opinions on TOPS? Is there something else I should be looking at?

Following! I want to do these too!

Well, TOPS might be a first very simple, very guided step in that direction. See samples (a page from each TOPS book) from the clickable links in the lower right corner of this page: https://topscience.org/books/pendulums01.html
