Let
the experiments begin!
Now you're ready to get down to the business of doing your
experiments or making your observations. Take your time.
If you rush through this part of your project, you might
miss an important discovery!
Pay
careful attention to the variables you decided you wanted
to observe. Repeat your experiments as many times as you
can, and when you repeat them, try to keep everything else
in your experiment the same.
If
you change more than one thing, your results may not make
sense. (If you changed your rocket engine, AND the fins,
AND the nose cone, you wouldn't be able to say why it went higher!) next...
